How to Learn SEO (Complete Roadmap)


Learning SEO can seem overwhelming. It’s a complex topic, and the industry is rife with misinformation. But with a bit of time, effort, and the right roadmap, it’s something that anyone can learn.

Here’s the roadmap we’ll cover in this guide:

1. Learn SEO fundamentals

If you’re not already familiar with the basics of SEO, this is where you should start. Specifically, you need to understand how search engines work and the four main facets of SEO. Let’s go through these real quick.

How search engines work

Search engines work by finding content and storing it in a big index. They then use complex processes, also known as search algorithms, to rank content from the index when a user performs a search. In other words, when you search for something on Google, you’re not searching the entire web—you’re searching Google’s index.

This means that if Google can’t find and index your content, you can’t rank because you won’t be indexed.

Google builds its index from two main sources:

  1. Sitemaps A sitemap is a file listing all the important pages on your website that you want search engines to index. You can submit your sitemap to Google to tell it that your pages exist.
  2. Links from known webpages – Google already has billions of pages in its index. If you get a link from one of those pages, Google can “follow” the link to discover your page.

Note that Google can discover new pages on your website by “following” links from known pages on your website too.

For example, if Google already has your blog homepage in its index, you can link internally to newly published blog posts from there. Google would be able to “follow” these links to discover newly published posts on your blog.

Keyword research

Keyword research is the process of finding what your customers are searching for. It’s important because you won’t get discovered if people aren’t searching for the keywords you target.

Because Google doesn’t exactly make this information accessible, the best way to find keywords is with a keyword research tool like Ahrefs’ Keywords Explorer. To use it, enter one or a few broad topics related to your industry, hit search, then go to one of the keyword ideas reports. You’ll see the keywords’ monthly search volumes and a few other SEO metrics.

In Keywords Explorer, we also show the “Traffic Potential” metric for each keyword. This estimates how much traffic the current top-ranking page for the keyword gets, which is usually a good indicator of how much traffic you can get by ranking #1.

As pages tend to rank for more than one keyword, “Traffic Potential” usually gives a more accurate estimate of a keyword’s potential than its search volume.

On-page SEO

On-page SEO is where you optimize the content on your page to rank higher on search engines. It revolves heavily around understanding what searchers want and giving it to them—a process known as optimizing for search intent.

For example, if we look at the top results for the keyword “best protein powder,” we see that they’re all blog posts comparing top picks:

Google SERP of "best protein powder"

This tells us that although searchers are in the market for a protein powder, they’re still weighing up their options and aren’t quite ready to buy. As a result, it would be tough to rank an e‑commerce product page for this query. That’s not what searchers want.

Link building

Link building is the process of acquiring backlinks from other websites to your site. It’s important because backlinks are one of Google’s top three ranking factors.

This is probably why there’s a clear correlation between linking websites and organic traffic:

Not all links are created equal, however. Links from relevant and high-quality websites usually move the needle more than links from irrelevant and low-quality websites. In other words, if your site is about Bitcoin, a link from a website about cryptocurrencies will likely positively impact rankings more than one from a website about travel.

Building high-quality links to your website is arguably one of the most challenging aspects of SEO and one of the most in-demand SEO skills.

Technical SEO

Technical SEO ensures that search engines like Google can find, crawl, and index your content. Unless they can do all three of these things, it’s unlikely that your pages will show up in the search results.

Let’s take a look at these three things in more detail.

  1. Find  Google first needs to know that your page exists and where to find it.
  2. Crawl  Google now needs permission to crawl the page. That’s where a computer program downloads the page’s content.
  3. Index Google now needs permission to add your page to its index.

You can solve the first part of the process by ensuring that your page has links from other known pages on your website and is in a sitemap that you’ve submitted to Google.

As for crawling and indexing, you need to ensure that you’re not blocking Google from doing either of these things. This is done using a file called robots.txt (crawling) and a meta tag called meta robots (indexing).

2. Put your knowledge into practice

Here’s an apt quote:

Knowing SEO theory is one thing; applying that knowledge to rank a website is another thing entirely. You’ll learn more about SEO in the trenches than any other way.

Will Critchlow

For example, when I was getting started in SEO, I created a bodybuilding website, as I was interested in the topic at the time. First, I made sure my technical SEO was on point and that Google could find, crawl, and index any content I published. I then did some keyword research to find topics to cover. After that, I began publishing optimized content.

Here’s the first post I published in August 2012:

Excerpt of article about best types of protein powder

Finally, I built some links.

Here’s one of the links I built with a guest post (it’s still live today… 10 years later!):

Excerpt of article about motivating yourself to go to the gym

This website ended up doing quite well, which validated that the SEO theory I’d learned made sense. However, I made some mistakes too. For example, I distinctly recall the rankings for a page tanking after randomly deciding to rewrite the copy. This taught me a valuable lesson that I didn’t learn elsewhere: If it ain’t broke, don’t fix it! 

3. Deepen your SEO knowledge

It’s impossible to learn absolutely everything about every facet of SEO. The topic is just too broad. So now that you’ve spent some time in the trenches and learned which aspects of SEO you enjoy, it’s time to niche down and deepen your knowledge in one area.

This is known as becoming a t‑shaped SEO.

T-shaped SEO

Being a t‑shaped SEO means that you have a broad knowledge of all things SEO but excel in one particular area. The area you choose to specialize in should be one that you’re best at and most enjoy.

For me, this is link building—which is why I’ve written much of our content about this topic.

Here are a few more examples of t‑shaped SEOs:

Notice how Marie Haynes’ specialty is hyperspecific? Instead of choosing one broad facet of SEO (e.g., keyword research or link building), she decided to specialize in the niche area of Google penalty recovery. As a result, there’s probably no SEO on the planet that knows more about this topic than Marie.

Going hyperspecific like this is a good idea if you’re learning SEO to become an in-demand SEO expert. But if you’re looking to rank websites, it’s probably better to keep things slightly broader and stick with one of the four main facets of SEO.

Either way, you should always test what you learn on your website. This is where true learning happens.

4. Keep your finger on the pulse

Despite what many people say, the fundamentals of SEO barely change. But small things are constantly changing. There are Google updates multiple times a year, changes to how search engines handle aspects of technical SEO, smart folks coming up with new tactics, etc.

With this in mind, while you shouldn’t spend all day every day reading SEO news, it’s important to keep your finger on the pulse.

Here are a few ways to do that:

Attend SEO conferences and meetups

SEO is a big industry with big conferences. For example, BrightonSEO attracts more than 4,000 attendees. There are numerous smaller meetups too, which you can find on, such as this one in my hometown. These are all places where like-minded people doing SEO share insights and tactics, so there’s a lot to learn from getting involved.

Listen to SEO podcasts

Podcasters often interview smart SEOs about their successes, failures, and experiences, making podcasts a great way to keep your finger on the pulse while on the go. For example, in this episode of the Authority Hacker podcast, link building extraordinaire Bibi shares her creative approach to link outreach emails.

Join SEO Facebook groups

Facebook has an active community of SEOs who are always willing to answer questions and offer advice should you need it. In fact, our Facebook group, Ahrefs Insider, has almost 17K members and is very active.

Join SEO Slack communities

If you’d prefer not to be distracted by Facebook, consider joining an SEO Slack community. Some are free, whereas others charge a monthly subscription. Traffic Think Tank (TTT) is a good choice if you’re open to paid communities.

Read SEO blogs

… Like the one you’re reading, where we often publish unique ideas, processes, and studies. For example, when Google switched to relying less on title tags to generate SERP titles, we studied almost a million pages and published the results for the community.

Watch SEO YouTube videos

… Like our YouTube channel, where we publish similar content to our blog.

Official sources

Google publishes official algorithm updates and announcements on the Search Console Blog and hosts weekly “office hours” hangouts on its YouTube channel. You can also follow Google search representatives like John Mueller and Gary Illyes on Twitter.

Read SEO news

Search Engine Roundtable describes itself as the pulse of search marketing and publishes daily updates on everything search. Search Engine Land and Search Engine Journal also frequently publish news.

5. Teach others what you know (optional)

Look back at the roadmap, and you’ll see a recommendation to share what you learn with others.

Learn SEO flowchart

This may seem counterintuitive, given that you want to learn more about SEO, but I find that teaching others helps me retain and assimilate knowledge. I think it’s because it forces me to articulate things, which often leads me to conclude that I don’t know as much as I thought I knew.

While you can do this publicly on a blog or YouTube channel, you can also do it semi-privately (in groups and communities) or privately (direct messages, face-to-face).

If you’re thick-skinned enough, doing it publicly often provides an extra line of defense against misinformation because people are usually kind enough to call you out when you get things wrong.

For example, here’s Bill Slawski pointing out an inaccurate claim in one of my articles on Twitter:

Bill's tweet about Google not ranking pages on the basis of content accuracy

This leads me to an important point…

Don’t try to teach others SEO unless one of these things is true:

  • You’ve thoroughly researched and understood what you’re teaching.
  • You’re teaching something based on personal experience and testing (and you’ve made that fact clear).

The last thing you want to do is…
