Basic SEO checklist

Let’s begin with the SEO best practices that you should employ before doing anything else.

Note that these things are unlikely to have a direct effect on rankings. They’re just the basics that every website owner should have in the bag.

1. Install Yoast SEO

Yoast SEO is a free SEO plugin for WordPress and a few other CMS’. It’s useful for creating sitemaps, optimizing meta tags, and much more.

2 yoast seo wordpress

In short, it makes the technical stuff less daunting.

If you’re not using WordPress or any other CMS’ supported by Yoast, then head over to Google and search for the best SEO plugin for your CMS.

2. Create a sitemap

Sitemaps tell search engines where to find the content on your site so they can easily crawl and index your pages.

Here’s what the sitemap looks like for our blog:

3 xml sitemap

You can usually find yours at

How do you create one?

If you’re a WordPress user, use Yoast. If not, Google a generator for your CMS.

3. Create a robots.txt file

Robots.txt is a plain text file that tells search engines where they can and can’t go on your site.

It’s always good practice to have a robots.txt file, but if you need to prevent search engines from crawling pages or sections of your site, it’s a must.  For example, if you run an ecommerce store, you might not want them to crawl and index your cart page.

4 robots txt

You can check if you already have a robots.txt file by going to If you see a plain text file, then you’re good to go. If you see anything else, search Google for “robots.txt generator” and create one. Web Design Company

4. Install Google Analytics

Google Analytics is a free tool from Google. It lets you see how many people visit your site and how they interact with it.

5 google analytics

To install it, sign up and paste the supplied tracking code into your website.

Read this guide (or watch this video for non-WordPress users) if you’re unsure how to do that.

5. Set up Google Search Console

Google Search Console lets you track search performance and see which keywords you rank for.

It will also keep you in the loop about on-site improvements you can make.

SIDENOTE. It’s also worth signing up for Bing Webmaster Tools, which is essentially Bing’s equivalent of Google Search Console.

Keyword research checklist

Keyword research is perhaps the most crucial piece of the SEO puzzle.

After all, if you don’t know what keywords people are searching for, how can you optimize your content for search engines?

Follow these checklist items to get off on the right foot.

1. Find a primary keyword to target

Each page on your website should target one main primary keyword.

That’s what we do with all posts on the Ahrefs blog.

12 Actionable SEO Tips → “SEO tips”

29 Best Free SEO Tools (Tried & Tested) → “free SEO tools”

Long-Tail Keywords: The ‘Secret’ to Getting TONS of Search Traffic → “long tail keywords”

You can find keywords using Google Keyword Planner or Ahrefs’ Keywords Explorer. Just type in a ‘seed’ keyword and check one of the keyword ideas reports.

For example, if we check the phrase-match report for “link building” in Keywords Explorer, we get over 5,000 keywords containing that phrase complete with SEO metrics like Keyword Difficulty and monthly search volume.

2. Assess ‘search intent’

Search intent is the reason behind a searcher’s query. If your page doesn’t align with this, then your chances of ranking will be slim to none.

To assess search intent, just check the top-ranking pages for the three C’s:

Content type: Are they mainly blog posts, product pages, landing pages, or product category pages?

Content format: Are they mainly lists, how-to guides, tutorials, opinion pieces, comparisons, reviews, or something else?

Content angle: Is there a dominant unique selling proposition used by the top-ranking pages? (e.g., for beginners, in 2020, etc.)

Let’s do this for “SEO checklist.”

Right away, we see that there’s only one type of page ranking and that’s blog posts. There are no product pages, landing pages, or anything else.

8 seo checklist serp content type

As for the content format, they’re all lists. There are no how-to’s, opinion pieces, tutorials, or step-by-step guides.

And the content angle seems to be freshness as almost all of the titles mention the year.

10 seo checklist serp content format

To stand the best chance of ranking for this keyword, we should create a list-style blog post and keep it updated year after year. And that’s what we did.

3. Research what people want to know

Let’s say that someone searches for “SEO keywords.” You can see from analyzing search intent that people are looking for a definition of the term, but what other questions do they have? And what other information should you include in your content?

Google’s “People Also Ask” box gives some insight into this:

11 people also ask

For more ideas, take three of the top-ranking pages and paste them into Ahrefs’ Content Gap tool. This will show you the keywords that one or more of the pages rank for.

12 content gap

It’s then just a case of eyeballing the results for keywords that might represent subtopics. In our case, that might be “keyword examples,” “how to search a page for keywords,” and “how to use keywords for SEO.”

12 content gap results

4. Assess your chances of ranking in Google

While no keyword is impossible to rank for in the long-term, some are darn near impossible in the short-to-medium term.

You can get a sense of keyword difficulty by looking at Ahrefs’ Keyword Difficulty score.

13 keyword difficulty

But don’t rely on that entirely. Check the results yourself for things that may indicate a hard keyword to crack like:

Lots of websites linking to the top-ranking pages

Lots of pages with high URL Ratings

Big brands in the top 10.

You can use Ahrefs’ SEO Toolbar to add all of that data to the search results.

14 ahrefs seo toolbar serp

Found a challenging keyword? Consider pursuing something easier in the short-term. You should always target keywords within your wheelhouse.

On-page SEO checklist

Keyword research = DONE.

Your next job is to optimize the actual content on your page, AKA, on-page SEO.

Let’s do it!

1. Use short, descriptive URLs

According to our study of over two million URLs, those with shorter URLs rank better.

15 characters in URL

SIDENOTE. Keep in mind that this is a correlation study. Correlation ≠ causation. 

But don’t sacrifice descriptiveness for length. Your URLs should offer insight into what the user should expect when they click through to the page.

The easiest way to do that is to set your target keyword as the URL.


This URL makes it clear what to expect from this page: a list of free SEO tools.

2. Write a compelling title tag and description

Most people tell you to add your target keyword to your title tag and meta description.

Is that bad advice? Not at all. - Web Design Services

It’s good practice, but don’t sweat it if it doesn’t make sense.

Most pages ranking on the front page of Google don’t have an exact-match keyword in their title tag. That’s according to our study of 2M keywords.

16 keyword in title

The same is true for meta descriptions.

17 keyword in meta description

Your primary goal shouldn’t be to shoehorn keywords into such places. Instead, work to craft an enticing title and description that will increase CTR and bring more traffic to your website.

3. Use one H1 on your page

Google’s John Mueller stated that it’s okay to use as many H1 tags as you want on your pages.

But we think it’s still good practice to use just one.

That’s because H1’s are typically used as a wrapper for the title of the page, and a page can only have one title.

But what about keywords? Should you include your target keyword in there?

According to our study of 2M keywords, around 85% of top-ranking pages don’t have their keyword in the H1 tag.

18 keywords in headline

That said, there are two important reasons to include your keyword here:

Scannability. Having your keyword in the H1 helps to reinforce to the reader that they’re in the right place. It makes it clear that your content tackles the topic they most-likely Googled before arriving on your page.

Link framing. People will often link to your page using the title. Including your keyword in the H1 will increase your chances of receiving links with your target keyword in the anchor text.


Find all the pages on your site with multiple H1’s using Ahrefs’ Site Audit.

4. Link to relevant internal and external resources

Web pages that link out to high-DR resources rank higher than those that don’t.

19 external links

IMPORTANT: That is the result of a correlation study. It doesn’t imply causation.

You should, therefore, not be afraid to link out to other web pages. Just make sure you link to relevant, high-quality stuff.

Internal links are also important. Whenever you publish something new, make an effort to add them from other relevant pages.

You can find these by searching for "topic"

For example, if we wanted to find relevant places from which to link to this article, we could search for “SEO checklist”

5. Optimize your images with descriptive alt text

Most top-ranking pages don’t have their target keywords in any of their alt attributes.

20 alt text

So alt tags aren’t particularly important then, right?

Not so fast. Remember that the point of alt text is to give the reader some context should the image fail to load (or if the visitor is using a screen reader).

For that reason, you should make sure alt tags are descriptive. This will often result in the natural inclusion of your target keywords.

Alt text is also helpful for ranking in Google Images.

6. Add schema markup for rich snippets

Schema markup helps search engines to understand your content better. But it can also dramatically affect how your page shows up in the SERPs.

Here’s a page with schema markup that currently ranks for “pizza dough recipe:”

21 rich snippets

Here’s what it would look without schema markup:

22 no rich snippets

Do you see the difference?

Schema markup can increase click-through rates and bring more traffic to your website.

It’s not that technical to implement either. Use Google’s markup helper or this Schema markup generator to do it with ease.

Content checklist

Picking a topic with high search traffic potential and doing some basic on-page SEO is important, but all your efforts will be in vain if your content isn’t up to scratch.

Follow these quick tips to level-up your content.

1. Write a winning intro

Fail to convince readers that your page offers what they want within a few seconds, and they’ll hit that back button faster than you can say “dwell time.”

This is known as “pogo-sticking.”

Your best defense against this is a compelling intro.

Good introductions should do three things:

Resonate with the reader;

Build trust;

Promise a solution to the user’s problem.

But is “pogo-sticking” even a Google ranking factor?

Here’s what Google’s John Mueller had to say on the matter:

We try not to use signals like that [pogo-sticking] when it comes to search.

John Mueller

John Mueller, Webmaster Trends Analyst Google

Interesting. But even if it’s not a direct ranking factor, there’s one other reason that a compelling intro is still important for SEO:

Nobody is going to link to your content without reading it in the first place.

So, to attract links, the reader first has to be engaged enough to read your content.

That’s why your introduction is arguably the most critical part of your page.

2. Focus on readability

Nobody wants to read a big wall of text.

That’s why you should always break up your content with subheadings, images, quotes—anything that will keep the reader glued to the page.

You’ll notice that we do that a lot on the Ahrefs blog.

We even use images in our intros to create the illusion that we’re getting stuck straight in, rather than wasting our readers’ time with a lengthy intro.

3. Use short sentences and paragraphs

50% of the US population read below an 8th-grade reading level.

US adult reading levels

So unless you want to alienate half of the population, don’t overcomplicate things.

That means using short sentences and paragraphs. Also:

Avoid unnecessary jargon;

Use simple words instead of complex ones;

Remove excruciatingly unnecessary adverbs.

4. Create the best piece of content on the topic

How do you create the best content on a given subject when it’s so subjective?

Answer: E‑A-T.

E‑A-T stands for Expertise/Authoritativeness/Trustworthiness. That is what Google claims to be looking at in their official search quality evaluator guidelines.

Here’s a more in-depth look at the three critical attributes of E‑A-T, taken from those same guidelines:

The expertise of the creator of the MC*.

The authoritativeness of the creator of the MC, the MC itself, and the website.

The trustworthiness of the creator of the MC, the MC itself, and the website.

* MC stands for main content. 

Learn more about these guidelines in section 3.1 here.

Technical SEO checklist

It’s not uncommon for technical SEO issues to hold a website back from ranking as high as it deserves.

The problem: Most people think technical SEO is daunting and complicated. - Web Development CompanyThe good news: It doesn’t have to be.

You can learn how to do a full SEO audit in this post (or in the video below).

SEO Increase Search Visibility

However, as this post isn’t solely focussed on technical SEO, what follows are a few common and easily solvable technical SEO issues.

1. Fix crawl errors

Crawl errors mean that Google is having trouble viewing the content on your site.

If they can’t view it, they won’t rank it. It’s as simple as that. That’s why you should fix these issues as soon as possible.

You can find crawl errors in Google Search Console > Coverage.

2. Make sure your site loads fast

Page speed has been a ranking factor on desktop since 2010, and on mobile since 2018.

It’s easy to see why. It’s frustrating to click on a search result and have to wait for it to load. That’s why the probability of a bounce increases with page speed.

25 bounce rate stats

You can use tools like PageSpeed Insights and GTMetrix to see how fast your web page loads.

However, these tools can only check one page at a time. To check all your pages, crawl your site with Ahrefs’ Site Audit. You’ll see slow pages flagged in the Performance report.

As a general rule, try to keep the load time below one second.

3. Fix outbound broken links

Broken links are bad for user experience, which is something that Google cares deeply about. That’s why they adjusted their algorithm to go after sites with too many distracting ads a few years ago.

To find broken links on your site, use Ahrefs’ free broken link checker.

4. Make sure your site is mobile-friendly

Most searches take place on mobile devices, so having a mobile-friendly website is more important than ever.

Check whether your site needs work with Google’s Mobile-Friendly Test tool.

5. Switch to HTTPs

HTTPS is a confirmed lightweight ranking factor.

If you’re not using HTTPS in 2020, then it’s probably time to make the switch.

Potential ranking boosts aside, HTTPs will protect your visitors’ data. This is especially important if you have any contact forms on your site. If you’re asking for passwords or payment information, then it’s not just important, it’s an absolute must.

SIDENOTE. You can get a free SSL certification from Lets Encrypt. 

6. Fix duplicate content issues

Duplicate content is exact or near-duplicate content that appears on the web in more than one place.

It’s a common ecommerce SEO issue thanks to faceted navigation. That alone can cause hundreds of duplicate content issues because of URL parameters.

You can find duplicate content issues with Ahrefs’ Site Audit.

Run a crawl, go to Duplicate content report, then hit the “Issues” tab.

30 duplicate content

Fix these by canonicalizing the affected URLs where necessary.

Link building checklist

Link building is perhaps the most challenging SEO task.

That’s because not everything is within your control. You’re often reliant on other people giving you links as a result of your outreach efforts.

So here are a few tried and tested link building tactics you can use:

1. Replicate your competitor’s links

Your competitors’ likely have at least some backlinks.

Believe it or not, that’s a good thing. If a website links to your competitor, chances are it’d make sense for them to link to you too.

Conclusion: You can build links to your site by replicating your competitors’ links.

How? There are many different ways. However, one quick win is to find sites that link to multiple competitors as the chance of them also linking to you is high.

You can do that with Ahrefs’ Link Intersect tool. Just enter a few of your competitors in the top section, then your site at the bottom.

31 link intersect

Hit “Show link opportunities” and look for any that might be easy to replicate, such as those from guest posts, link roundups, forums, directories, etc.

32 link intersect results

2. Monitor and reclaim any lost links

Diamonds are forever. Links aren’t.

Want proof? Just check the Lost Links report in Ahrefs’ Site Explorer for any website. You’ll see the loss of many links in recent months.

Here are the lost links to Ahrefs’ Blog over the past seven days:

33 lost backlinks

Links disappear like this for all kinds of reasons. Sometimes they’re gone for good. Other times it’s possible to reclaim them.

What are the easiest ones to reclaim?

Links marked as “noindex” in Ahrefs.

34 noindex lost link

Most of the time, these are lost because the site owner accidentally noindexed their website. Web Development Company India, So you can reclaim them easily by reaching out and letting them know about their possible mistake.

3. Pursue unlinked mentions

People will sometimes mention your brand without linking to you. These are known as unlinked mentions.

Here’s an example of one:

35 unlinked mention

You can see that even though they mention Ahrefs, they don’t link back to us.

Now, wouldn’t it be cool if you could convert unlinked mentions for your brand to linked mentions?

It would, and you can. Just reach out to the authors and request that they “make the text clickable.” Because they’re already familiar with your brand, there’s a high chance that they’ll happily make that change for you.

However, the question remains: How do you find unlinked brand mentions in the first place?

Everything is explained in the guide below.

Recommended reading: A Simple Guide to Turning (Unlinked) Brand Mentions into Links

4. Let the right people know about your content

People can’t link to content if they don’t know it exists.

That’s why you should make a conscious effort to tell people—the right people—about your content. But who are the “right” people?

They have two attributes:

They are likely to be interested in your content;

They have the power to link to you.

These people are known as the “linkerati.”

You can let them know about your content by performing blogger outreach. - Web Development Company India
