This is NOT a lame “SEO in 2019” predictions post.

Yes, I’ll cover the most important SEO trends for 2019.

But you’re also going to see strategies that are working right now… and will work even better in 2019.

So if you’re looking to up your SEO game this year, you’ll love this guide.

Chapter 1:RankBrain & UX Signals

RankBrian and User Experience Signals

User experience signals were HUGE this year. And I expect them to be an even more important SEO trend in 2019.

In fact, Google previously announced that RankBrain was their third most important ranking factor:

“In the few months it has been deployed, RankBrain has become the third-most important signal contributing to the result of a search query.”

The question is:

What is RankBrain, exactly? And how can you optimize for it?

Google RankBrain: a Dead-Simple Explanation

RankBrain is a machine learning system that helps Google sort their search results.

That might sound complicated, but it isn’t.

RankBrain simply measures how users interact with the search results…

…and ranks them accordingly.

For example, let’s say you search for “cold brew coffee” in Google.

Cold brew coffee

The #4 result looks especially enticing. So you quickly click on it.

And when you get there…wow! It’s the best darn article about coffee you’ve ever read. So you devour every word.

RankBrain is going to take note…and likely give that #4 result a rankings boost.

Pogo-stick effect

On the other hand, let’s say that you do the same search. But this time, you click on the #1 result without even looking.

But the content is TERRIBLE. So you bounce from the page after a few seconds.

Pogo-stick effect

And you click on the #4 result to find something about coffee that’s actually worth reading.

RankBrain will also notice this. And if enough people quickly bounce from that result, Google will boot it from the #1 spot.

Pogo-stick effect

As you can see, RankBrain focuses on two things:

1. How long someone spends on your page (Dwell Time)
2. The percentage of people that click on your result (Click Through Rate)

Let’s break each of these down.

RankBrain and Dwell Time

Dwell Time=how long a Google searcher spends on your page.

As it turns out, RankBrain pays A LOT of attention to Dwell Time.

In fact, the head of Google Brain in Canada recently confirmed that Google uses Dwell Time as a ranking signal.


He stated that RankBrain measures when:

“someone clicks on a page and stays on that page, when they go back”

Dwell time

And a recent industry study by SearchMetrics supports this statement. They found that the average Dwell Time for a top 10 Google result is 3 minutes and 10 seconds.

If you’ve spent any time digging through your Google Analytics, you know that a 3+ minute Dwell Time is legit.

And it’s no coincidence that pages with awesome Dwell Time tend to rank best. In fact, RankBrain is upranking these pages for that exact reason.

This makes sense if you think about it:

If you spend a long time on a page, you probably like the content on that page.

And if enough people feel the same way, Google will uprank that content to make it easier to find.

If you want to improve your site’s Dwell Time, check out this video:

RankBrain and Organic Click Through Rate (CTR)

Google Engineer Paul Haahr caused a stir in the SEO world when he put up this slide at a conference:

Paul Haahr

This slide basically says:

“RankBrain sometimes ranks pages higher up than they “should” rank.

And if that page gets an above-average CTR, we use that as a sign that the page should get a permanent rankings boost.”

This shouldn’t come as a surprise. After all, if no one clicks on your result, why would Google keep it on the first page?

And if your site is getting clicked on like there’s no tomorrow, why would Google keep it buried in the #9 spot?

If you want a few simple strategies that you can use to boost CTR, check out this infographic that I made with Larry Kim.

Speaking of click through rate…

Chapter 2:Become a CTR Jedi

CTR Jedi

If you want to master SEO in 2019, you need to become a CTR Jedi.

Yes, because of RankBrain.

But also because of:

Google Ads


Google Lists

And most deadly of all… The Featured Snippet:

Google Wiki result

(More on that in Chapter 3)

In fact, one industry study found that organic CTR on mobile search is down 41.4% since 2015.

Mobile Organic .vs. Paid CTR

It’s no secret why: Google is crowding out the organic search results with Answer Boxes, Ads, Carousels, “People also ask” sections, and more.

And to stand out in the SERPs, your result needs to scream “click on me!”… or else it’ll be ignored.

This video will help you boost your CTR using what I call “The Click Magnet Method”:

Chapter 3:Rank Content In The Featured Snippet

Rank content in the Featured Snippet

According to SEMrush, 11.3% of all search results now have a Featured Snippet.

And yes: Featured Snippets are stealing A LOT of clicks from the #1 spot.

(As I like to say: “#0 is the new #1”)

The question is:

How do you get your content to appear in the Featured Snippet?

Well, that’s what this chapter is all about.


First, find Featured Snippet opportunities

Your first step is to find:

  1. Keywords that you already rank for
  2. Keywords that have a Featured Snippet

Why is it important to focus on keywords that you rank for already?

99.58% of all Featured Snippets are from pages that rank on the first page for that term.

So if you don’t already rank in the top 10, you have no chance of getting in the Featured Snippet spot.

How do you find Featured Snippet Opportunities?

Ahrefs “Organic Keywords” report.

It shows you keywords that you rank for… that have a Featured Snippet:

Ahrefs – Keywords you rank for

2,416 keywords? Looks like I have some work to do 🙂


Next, create “Snippet Bait”

“Snippet Bait” is a 40-60 word block of content specifically designed to rank in the Featured Snippet spot.

Why 40-60 words?

Well, SEMrush analyzed nearly 7 million Featured Snippets. And they found that the most Featured Snippets are 40-60 words long.

Most featured snippets are 40 to 60 words long

For example:

I wrote short Snippet Bait definitions for every page of The YouTube Marketing Hub.

YouTube Hub – Channel Keywords

And these helped my content rank in the Featured Snippet spot for lots of definition keywords.

HubSpot takes Snippet Bait to another level.

They add little boxes to their posts that actually look like Featured Snippets:

HubSpot – Featured Snippet


Finally, format your content for other types of Featured Snippets

Snippet Bait works best for so-called “Paragraph Snippets”.

Here’s an example:

Paragraph snippet

Even though paragraph snippets are by far the most common type of Featured Snippet

Type of Featured Snippet

they’re not the only one.

If you want to rank in List Snippets…

Use H2 or H3 subheaders for every item on your list.

List snippets h3

Google will pull those subheaders from your content… and include them in the Featured Snippet:

Featured Snippet content

If you want to rank in Table Snippets…

You need to create a table that Google can easily pull data from.

For example, the content from this Table Snippet…

Table snippet SERPs

…is pulled directly from a well-formatted table.

Table snippet – Source site

So yeah, I’m just getting my feet wet with Featured Snippets.

But it’s going to be a big focus of mine in 2019.

And now it’s time for…

Chapter 4:Comprehensive, In-Depth
Content Wins

In-Depth Content

In the old days, Google would analyze your page’s HTML to see how many times you used a specific keyword.

In other words, they focused 100% on your page’s content. So the Google spider would visit your page to check if your keyword appeared in your:

  • Title tag
  • URL
  • Image ALT text
  • Description tag
  • H1 tag

Traditional page-level ranking factors

To be fair, they still look at traditional on-page SEO stuff. But today’s Google is MUCH smarter than it used to be.

So instead of only measuring content, they now focus on context.

What do I mean?

Remember: Google’s #1 job is to show their user the BEST result. And in most cases, the “best” result isn’t a piece of keyword-stuffed content.

Instead, the best pages cover an entire topic in-depth.

With in-depth content, a Google searcher gets everything they need in one place (one stop shopping).

In fact, our ranking factors study found that in-depth content tends to rank best in Google.

Content topic authority

How To Write Comprehensive, In-Depth Content

So: how can you write the type of in-depth content that Google wants to see?

First, publish content that’s at least 2,000 words. That way, you can cover everything a Google searcher needs to know about that topic.

In fact, our ranking factors study found that longer content (like ultimate guides and long-form blog posts) outranked short articles in Google:

Content total word count

Publish Authoritative Evergreen Content

Earlier this year BuzzSumo analyzed 100 million articles.

BuzzSumo – 100,000,000 articles

What did they find?

First, the bad news:

  • The average blog post gets a grand total of FOUR total social media shares
  • Facebook traffic is down 50% since 2015
  • 70% of all online content gets ZERO backlinks
  • Pageviews are down across the board:Average post shares

Now for the good news:

Certain TYPES of content are killing it right now.

As BuzzSumo founder Steve Rayon concluded from his research:

Lucky for me, that’s exactly the kind of content that I publish at Backlinko.

And it works GREAT.

For example…

Earlier this year I noticed that lots of digital marketing blogs were publishing content about mobile optimization.

Digital marketing blogs

These posts were OK.

But I didn’t see anything that you’d call “authoritative evergreen content”.

So I decided to create just that.

The result?

Mobile SEO: The Definitive Guide.

Mobile SEO: The Definitive Guide

I published this post in March.

Since then that post has racked up 2,630 social shares:

Mobile SEO Guide – Social shares

And backlinks from 1.7k domains:

Mobile SEO Guide – Backlinks

Add LSI Keywords to Your Content

Once you’ve put the finishing touches on your 2,000-word monster, add LSI keywords to it.

LSI keywords are words and phrases that are strongly associated with your page’s topic.

For example, let’s say that you just published an article about The Paleo Diet.

LSI keywords would be terms like:

  • Nutrition
  • Caveman
  • Weight loss
  • Recipes
  • Grains

And when Google sees these LSI keywords on your page, they think: “Awesome! This page obviously covers this topic really well.”

How do you actually do LSI keyword research? Here are three simple strategies:

First, use a nifty free tool called LSI Graph.

LSI Graph

Just enter your target keyword into the tool, and it’ll show you a bunch of LSI keywords that are associated with that term:

LSI Graph – Results

Add any of these that make sense to your content.

Second, use good ol’ Google. Just search for your target keyword. Then check out the “Searches related to…” section at the bottom of the search results.

Related searches

The words in bold here are LSI keywords.

Finally, you can hack the Google Keyword Planner for LSI keyword ideas. Here’s how:

Pop your keyword into the Google Keyword Planner. And click “Get Started”.

Keyword Planner

Then, scan the results. Many of these are LSI keywords.

Keyword planner results

Just like with the other strategies I showed you, sprinkle LSI keywords from the Google Keyword Planner into your content.

Chapter 5:Optimize for Google’s Mobile-First Index

Google Mobile-first Index

A few months ago, millions of people got “Mobile-first indexing enabled” messages.

Which means: Google now considers the mobile version of your site the “real” version. And this is the case even if someone searches from a desktop.

This move makes sense. Today, 60% of Google searches are from a mobile device. And mobile searches are growing fast.

Even though Google’s Mobile-first index isn’t live for everybody yet, it’s rolling out as we speak. So whether you got the heads up from Google yet or not, it’s time to get ready.

How to Optimize for Google’s Mobile-First Index: 3 Simple Steps


Make Your Content Consistent Across Desktop and Mobile

You know how sometimes people hide content on the mobile version of their page?

Here’s an example:

Consistent content

Well, that’s a BIG problem with the Mobile-first Index.

That’s because Google considers the mobile version of your page the “true” version.

Google – Mobile-first search model

Which means that hidden content is 100% ignored by Big G.

Yes, even though Google has said that tabs, accordions and other features that hide content on mobile is OK…

Google Webmasters – Hidden content

one recent industry study found that “hidden content appears to be devalued in mobile-first index.”:

Hidden content is devalued

For example, when you visit this post on the Backlinko blog from an iPhone, you get the same high-quality content that desktop users get 🙂

Ultimate SEO Audit

As you can see, there’s nothing hidden behind buttons, menus, or expandable sections.


Move From m. to Responsive Design

Do you have a mobile “M.” version of your site? Google recommends switching over to responsive design.

So do I.


Make Sure Your Site Kicks Butt On Mobile

I see lots of sites that technically work on a phone or tablet. But they’re a huge pain to actually use (or have a super slow mobile page speed).

Like I mentioned in Chapter 1, RankBrain closely measures how Google users interact with your site.

And if people have a hard time using your site with their phone, they’re going to hit their “back” button without thinking twice.

How do you know if your site is legit mobile friendly?

I recommend checking out the nifty Mobile-Friendly Test tool from Google. Just enter a URL into it, and the tool will let you know if your site is mobile-friendly:

Mobile-Friendly Test

They’ll even hook you up with recommendations that you can use to up your mobile game.

Mobile-friendly Test – Results

You can also check out the Mobile Usability report in the Google Search Console:

Google Search Console – Mobile Usability Report

It lets you know about pages on your site that aren’t mobile-friendly… and how to fix them:

Google Search Console – Mobile issue: Content wider than screen

Chapter 6:Go All-In With Video (Or Get
Left Behind)

Video SEO 2019

Online video is EXPLODING right now.

In fact, according to Cisco, online video will make up 80% of all online traffic by 2021.


And that may still not satisfy the world’s demand for video.

Despite the fact that there are more videos out there than ever, HubSpot states that 43% of people want to see MORE video content.

In short:

If video isn’t part of your digital marketing plans this year, you’re missing out. Here’s how to take advantage of video’s SEO benefits this year.

Tap Into YouTube

YouTube is already the world’s 2nd largest search engine.

(In fact, according to a study by JumpShot and Moz founder Rand Fishkin, YouTube’s search engine is 2x more popular than Bing)

Search engine popularity

And like any online video platform, it’s growing fast (The Huffington Post reports that the amount of time that people spend on YouTube is up 60% compared to last year).

In short, more and more people are searching for stuff on YouTube… and skipping Google altogether.

So if you want to get more traffic from SEO in 2019, I recommend creating and optimizing content specifically for YouTube.

It’s a search engine that’s too big to ignore.

The best part? Most marketers are too lazy to make videos. So it’s pretty easy to get your videos seen (assuming you know what you’re doing).

For example, my channel has 25 total videos. And those 25 videos generate over 200k views per month.

Videos generate over 200,000 monthly views

(And as you might expect, a good chunk of those viewers turn into website visitors, leads and customers).

It gets better: when you publish SEO-optimized YouTube videos, you’ll own more Google real estate.

Why? Well, for starters: 55% of all Google search results contain at least one video.

Google Search with video

(And almost all of those videos are from YouTube).

Here’s an example of what I mean:

YouTube SEO

And considering that Google owns YouTube, expect even MORE YouTube videos in the search results in 2019.

In fact, Google has started to blend YouTube results into Google Image search:

Video results

And use massive “Video Featured Snippets” to answer people’s questions:

Video Featured Snippet

Embed Video Content Into Text-Based Blog Posts

If people want to see more video, why not give it to them?

That’s why I recommend embedding video content into your blog posts. In my experience, this can give you a serious dwell time boost.

Here’s an example of this in action:

Embed video content

Chapter 7:Optimize for Voice Search

Voice Search

Is voice search “the next big thing” in SEO? It certainly looks like it.

For example, check out these eyebrow-raising facts:

  • 41% of adults perform at least one voice search every day (source)
  • Voice searches performed in Google are up 35x since 2008 (source)
  • 20% of all searches on mobile are voice searches (source)

Knowing that, smart SEOs are starting to optimize some of their content for voice search.

Including me 🙂

How to Optimize for Voice Search

In early 2018 we conducted the largest voice search SEO study to date.

Voice Search SEO

Here’s what we found:


First, your content needs to rank high in the search results.

We found that Google tended to source voice search answers from content that ranked in the top 3 search results:

Voice answers tend to come from the top three results


Next, it helps A LOT if your content appears in a Featured Snippet, like this:

Google’s algorithm has already put together a convenient little snippet.

So it makes sense that they would use that snippet in their voice search results.

In fact, our data revealed that 4 out of 10 voice search results come directly from a Featured Snippet.

4 in 10 voice search results come from a Featured Snippet


Finally, include a question (and answer) in your content.

The vast majority of voice searches are question based (“How do I do a pullup?” or “Who starred in Shawshank Redemption”?).

When that happens, Google usually picks a page that contains a) the question and b) the answer.

For example:

When I search for:

Google Voice Search

I get this answer:

Google voice search results

And when I go to the actual page, I see that the content includes my question and a short answer:

How do weather satellites work?

Just what Google’s voice search algorithm wants to see.

In fact, that’s one of the main reasons that FAQ pages are GREAT for voice search SEO:

FAQ pages are great for voice search SEO

Chapter 8:Don’t Forget: Content and Links
Are Key

Content and links

Even with all of the important SEO trends that I’ve covered in this guide, SEO in 2019 is still all about content and links.

Without amazing content, you’ll never get links.

And without link building, you won’t crack the first page.

Also, if you’re not on Google’s first page, RankBrain, Voice Search and the Mobile-first algorithm won’t matter.

Those only come into play once you already rank on page 1.

In fact, Google recently came out and said that content and links are their #1 and #2 ranking factors:

Google top ranking factors

And when we analyzed 1 million Google search results, we found that the number of sites linking to a page correlated with rankings more than anything else.

Number of referring domains

In short, quality content and links will still be the foundation of SEO in 2019.

And once you have a handle on that, it’s time to optimize your site for the new SEO trends that I outlined in this guide.

Bonus chapter:Quick Tips for SEO in 2019

SEO Tips for 2019

In this chapter I’ll show you a few quick win tactics that will work especially well in 2019.

Improve Your Site’s E-A-T

On August 1st, Google rolled out a new “core update” to their algorithm.

August 2018 – Google update tweet

This update was a biggie.

(In fact, it’s the biggest change I’ve seen in the SERPs since Penguin in 2012).

There are 2 really interesting things about this update.

Thing #1: This update HAMMERED certain sites in the health niche.

Here’s an example:

Health niche site traffic drop

So even though this was a “broad” and “core” algorithm update, health sites really felt the heat.

In fact, one small survey found that 41.5% of sites hit by this update were in the health niche:

Verticals affected by Google medic update

(Compared to only 5.9% in the tech space. And 3.5% of sites in the travel niche).

Thing #2: Google updated their Quality Rater Guidelines right before this update.

On July 20th Google released their new Quality Rater Guidelines.

Google quality rater guidelines

This document was pretty much the same as last year… with one major change:

A focus on E-A-T.

(Expertise, Authoritativeness, and Trustworthiness)

EAT section of guidelines

To be clear:

E-A-T has been a part of the guidelines for years.

But there was a new emphasis on E-A-T this year.

(Probably to train their raters for this update).

Here’s how to bump up your site’s E-A-T.

First, be an expert (or hire one).

If you hire random freelancers to write your content, you’re in trouble.

That’s because Google wants to feature content written by experts.

Google Guidelines – Hire experts

This is tough to fake.

In fact, Google might be using a form of Google Authorship to figure out whether or not an author is an expert in that space.

Google may be using a form of Google Authorship

Next, be transparent.

Google probably focuses on off-site signals to figure out your site’s E-A-T.

That said:

The rater guidelines spend a lot of time on evaluating the site itself.

For example, the guidelines point out that:

This means having:

  • Thorough about page
  • Easy to find contact page
  • References and external links to sources
  • Privacy policy and terms of service

Create Visual Content (Especially “Embeddable Images”)

Just like video, visual content is growing fast.

In fact, a recent poll found that 37% of marketers stated that visual marketing was the most important form of content for their business.

And thanks to social media sites like Pinterest and Instagram, visual content should continue to see growth in 2019.

How can you take advantage of this trend?

Create more visual content… especially “Embeddable Images”.

In my experience, “Embeddable Images” can do just as well as a fancy infographic…if not better.

(Embeddable Images are images that are easy for other sites to embed into their content. When they do, they’ll usually link back to you).

For example, here’s a simple visual that I included in one of my guides:

RankBrain visual

It’s nice…but pretty simple.

Even so, people LOVE embedding this image in their content:

Visual included in a guide

And because of that, that single Embeddable Image has generated a handful of high-quality backlinks to my site.

Publish Unique Data

Bloggers and journalists LOVE unique data.

And if you can hook them up with a stat, a survey, or an industry study, they’ll throw links at your feet like rose petals.

For example, last year we published this study of YouTube ranking factors:

YouTube ranking factors

This content contains lots of data that people can cite (like the fact that the average video on the first page of YouTube is nearly 15 minutes).

And cite they do! This page has racked up backlinks from over 340 different domains in a little over a year:

YouTube Ranking Factors – Results

And brought in a boatload of search traffic.

Encourage Comments on Your Site

Do blog comments help your rankings?

The answer seems to be: “YES!”.

In fact, Google stated that community (blog comments) can help “a lot” with rankings.

Encourage comments

And last year Google said that “Comments are better on-site for engagement signals for SEO than moving to social.”

In other words, Google wants to see that you have an active community on your site. And they’re likely to pay even more attention to this ranking signal in 2019.

Prune Zombie Pages

This is one of the few SEO techniques that seems to ALWAYS work.

I’ll explain…

Every site has pages that provide zero value.

(aka “Zombie Pages”)

Zombie pages

To be clear:

A handful of Zombie Pages is no big deal.

But when you have hundreds or thousands of Zombie Pages?

It can drag down your entire site’s SEO.

For example:

Joe Robinson is a Backlinko reader that runs the digital marketing agency, Kazu.

And Joe noticed that one of his clients had 76 thin, low-quality articles on their site:

Kazu – Client – Old content

So he consolidated some of these articles into in-depth guides…

Kazu – Client – New improved content

…and deleted or forwarded the rest.

What happened next?

His client’s organic traffic increased by 16.23% in 30 days:

Kazu – Client – Traffic increase

And traffic continued to climb as Google removed Zombie Pages from their index.

Traffic increase after removing zombie pages

Joe isn’t alone.

Alan Boyd emailed me a cool little case study last week.

Alan’s client is a tour company out of Palm Beach Florida.

Alan – Water sports client

And he quickly noticed that this site had 50 service pages that all said pretty much the same thing:

Alan client – Duplicated service pages

So he combined the content from those 50 pages into 4 category pages:

Alan client – Category page solution

And that single tactic increased their search traffic by 36.9%:

Alan client – Traffic increase

Here’s one more quick example to really drive this home.

Bart runs the web design SaaS company called Readz.


Back in the day, Bart would publish content just for the sake of publishing content.

And this bloated his site with low-quality posts, like this one:

Readz – Low quality content

Then, earlier this year? He deleted/consolidated 45 low-quality blog posts.

At first, his traffic dipped.

But as the algorithm kicked in, his organic traffic rapidly shot up by 32%:

Readz – Organic traffic increase

Pretty cool.

Go On Podcasts

Podcasts are one of my all-time favorite ways to build links.

It’s like guest posting… without all the BS. Just show up, provide value, and you get a sweet backlink:

Podcasts for SEO

And podcasting’s popularity is growing like a beanstalk. In fact, 67 million Americans listen to at least one podcast per month (that’s up 14% vs. last year).

That means that there will be even MORE opportunities for you to get links from podcasts in 2019.


So that’s how I’m preparing for SEO in 2019.

Now I want to turn it over to you: Which of the steps from today’s guide are you going to implement first?

Are you going to optimize your content for dwell time? Or work on making your site more mobile-friendly?
