16 Step Guide To Completing An SEO Audit [Bonus: SEO Audit Checklist Download]

There’s a whole world of technical SEO that needs tending to for a site to perform and convert at its best. But how do you manage the many, many tasks involved in keeping a site’s SEO healthy? I already covered some of these things in my previous blog post How To Complete A Technical SEO Audit [+ Free Audit Checlist], but I want to focus on the process of conducting an SEO audit in this step-by-step guide.

Maintaining your site doesn’t have to be a daunting undertaking. I like to break up site checkups into manageable tasks that occur throughout the year and annually. To make it even easier, below is a how-to on breaking down all the tasks you need to perform for a kick-ass SEO audit separated into a schedule: monthly, bi-monthly, quarterly, and yearly to keep it organized.

Get your calendars handy, download the SEO Audit Checklist, and let’s dive in!


Monthly Checkups: Schedule These Once A Month

To set yourself up for SEO success, there are a couple of tasks that need frequent attention. Keeping these elements up to date can be the difference between your site’s new pages being indexed by Google or being completely overlooked. (Google has to index your site to rank it.) 

Perform these checkups once a month if you are adding content regularly.

1. Review Sitemaps and Update if Necessary

Updating and resubmitting your sitemap when you make changes to your site is key to a healthy search presence. While it’s not guaranteed to rank you any faster, there’s no harm in being certain Google has the right version of your site on file to index.

Review your sitemap monthly, generate an updated version if applicable, and re-submit it to search engines via Google Search Console

To keep an eye on your indexation rates for anomalies, review your sitemap in Search Console along with doing a “site:randomurl.com” search in Google. The numbers should be about the same between Search Console and Google’s index.

Here are detailed instructions for submitting an updated sitemap to Google Search Console.

2. Review 404 Errors and Schedule Fixes if Necessary

While 404 pages do not directly harm your site’s SEO, trust and usability do, as they are major factors in your users’ experience. If your site has 404s, trust and UX can tank. 

A 404 error (meaning a webpage on your site cannot be found) can send users away from your site, increasing bounce rate and decreasing your site’s trustworthiness. Fortunately, 404s are often just the result of a broken link or a bad redirect. 

To keep search engines and users happy, run a monthly crawl in Search Console to locate errors and fix them. You may also want to set up a custom 404 page so if a user does land on a 404 page, they can be redirected somewhere relevant. The folks at Creative Bloq put together a nice blog post full of examples of great 404 pages, so check those out.

3. Review Accelerated Mobile Pages (AMP)

Accelerated Mobile Pages (AMP) are web pages designed according to an open-source specification. AMP HTML is a subset of HTML for authoring content pages such as news articles in a way that guarantees certain baseline performance characteristics. AMP HTML documents can be uploaded to a web server and served just like any other HTML document; no special configuration for the server is necessary. These are lightweight pages designed to load quickly on mobile devices, which is a characteristic you need in 2021 and beyond. 

Updating your code to AMP HTML may include things like:

  • Replace image references with images sized to the viewer’s viewport.
  • Inline images that are visible above the fold.
  • Inline CSS variables.
  • Preload extended components.
  • Minify HTML and CSS

These updates will provide performance benefits, allowing them to be served quickly in Google search results. For more information regarding how this directly affects your Google results, read and follow the Google guidelines.

To monitor how your AMP pages are performing, head over to Search Console again. You can access the report under the Search Analytics where it shows the search appearance filter.


The AMP Status report will help you monitor your AMP status, as well as diagnose and correct any errors in your AMP pages. You’ll see a chart of AMP pages successfully indexed as well as pages with AMP-specific errors. Update your top landing pages today and see how much growth you gain.

Bi-Monthly Checkups: Schedule These About Every 8 Weeks

Completing these checkups consistently will help account for any SEO loose ends you may accidentally create as you update and maintain your site. These tasks, though just as important as your monthly checkups, can be performed every other month.

1. Review Structured Data

Not every site utilizes “rich snippets” (the result of structured data) and that’s ok. There are many types of sites where they are not appropriate (see Google’s list). 

Those that are on that list (anything that gets reviews, really) should be using these to enhance their clickthrough rates and rankability. Rich results can be particularly eye-catching next to non-rich results. These snippets can manifest as the average star rating of a business, photos for a recipe, customer product reviews, or an author bio, just to name a few. 

They make search results easier to skim, and if they contain the information the user is looking for, they’re more likely to be clicked. 

In fact, having a page appear with rich snippets in SERPs can improve clickthrough rates of 20-30%, according to Moz. Every other month, head to Search Console to find Structured Data and check your metrics for structured data numbers and performance. Keep an eye out for decreases and errors, and implement fixes where needed.

2. Test Site Speed

Site speed isn’t just an important element of technical SEO. Poor page load speed will send users running from your site to a competitor. Good page load speed leads to higher user satisfaction with higher engagement rates and more links—all signals that Google pays attention to. Take advantage of Google’s PageSpeed Insights to check your site’s speed on both mobile and desktop during an SEO audit.

3. Check Title Tags

Title tags are one of the most important SEO elements on your site—and also one of the easiest to optimize. Check that each of your title tags is optimized for its page’s appropriate keyword, and make sure there are no missing, duplicate, too-long, too-short, or non-informative title tags. 

Keep in mind that the maximum character count before the title gets cut off in SERPs is ~67. Additionally, be sure to avoid the once-standard title tag formula (primary keyword + secondary keyword + brand name). Instead, include the page’s primary keyword, but make the title more compelling to read from a user’s perspective (rather than a search engine’s).

4. Check Meta Descriptions

Like title tags, meta descriptions are another piece of metadata that should always be optimized. A good meta description will not just be valuable to search engines, but will also contain useful information and good copy to draw the user in. 

Google will only show ~155 characters in SERPs (though it will index more), so make sure the necessary user-friendly copy is short enough to appear in full in the results. Make sure all of your pages have meta descriptions that are unique, the right length, informative, and contain your target keyword for that page. I recommend using the keyword exactly as it appears in your keyword research tool (rather than a variation of that keyword).

5. Check H1s

A strong H1 is a critical on-page ranking factor. It guides the user’s eye, orients them on the page, and tells both users and search engines what the page is about. Just like its other metadata counterparts, H1s should be keyword-optimized, unique, and informative.

6. Check Alt Tags

This out-of-sight page element should never be out-of-mind. The text of your alt tags offers another opportunity to tell search engines, as well as visually impaired users, what your site is all about. It also increases your potential to rank in Google Image Search. 

As with other pieces of metadata, make sure each alt tag is unique, optimized for a target keyword, and descriptive.

7. Spot-Check Site Content

Careful as you may be when crafting content for your site, there’s always room for improvement. It’s always a good idea to rerun a site crawl using Screaming Frog and make sure you don’t have any duplicate pages, your word count is healthy, and that your meta is in place. 

Also, run a site:mydomain.com search in Google to make sure your content is being indexed. Check your site to make sure all your content is serving a purpose, well-optimized, and error-free.

Quarterly Checkups: Schedule These Once Every 3 Months

Your quarterly checkups will help you take a look at the bigger picture on a regular basis. You’re doing more than just focusing on fixing individual factors—you’re evaluating the overall performance of your site, reviewing its health, and adjusting your strategy as you go.

1. Assess Keyword Targets

This is an excellent opportunity to measure the success of your SEO strategy. Are you gaining ground on the keyword targets you’ve chosen, or should you think about re-optimizing? Check-in with your go-to tools (AdWords, Ahrefs, Search Console, etc.) to view your targets’ most recent search volume and competition.

2. Run “Links To Your Site” Report in Search Console to Check for Bad Links

A quarterly check for bad links helps ensure that Google has nothing to penalize you for in the way of low-quality or spammy-looking links. Whether the links are remnants of a bygone backlinking strategy or come from someone else, you’ll need all your links to be squeaky clean to keep your SEO healthy. Run a checkup in Search Console every 3 months to remove the links that need removing, and to disavow those that can’t be removed.

3. Look at Historical Site Performance to See How Current Performance Compares to Past Performance

Reviewing long-term site performance can be tricky. Use Google Analytics to take a quarterly look at your site’s performance during the current quarter, the past 12 months, and for all time. You’ll want to be on the lookout for anomalies in your traffic and conversions, whether those anomalies be spikes or dips. Keep in mind that a decrease isn’t always bad, and an increase isn’t always good—it’s all about context. When you find a particularly interesting piece of data, dig into your timeline and your channels to find its cause.


4. Review Robots.txt

Your robots.txt file resides in the root of your website’s folder and communicates a certain number of guidelines to search engine crawlers. You’ll need to check it to make sure crawlers are reaching what you want them to and ignoring what you don’t. You can include your sitemap in your robots.txt—just make sure you don’t disallow the sitemap. Test your robots.txt for errors using Search Console.

5. Check on All Items Covered in Monthly and Bi-Monthly Checkups

The title says it all, make the rounds on everything covered above as a part of your quarterly checkup. From 404s to alt tags, leave no SEO audit stone unturned.

Yearly Checkups: Schedule These Once A Year

Finally, your annual checkup allows you to take your strategy assessment to the next level. These once-a-year tasks are more intensive, but can also yield an enormous payoff when applied correctly.

1. Content Audit

Running a yearly content audit on your site will give you a bird’s-eye view of your site’s content, allowing you to see the best and worst-performing content from a variety of angles. 

Define your KPIs, use a crawler(s) to pull all the data you need, and start sorting. As you analyze your content, you’ll be able to spot opportunities and make educated decisions about what to do with each piece of content.

For each URL on your site, decide whether you will apply one of the following actions: a) Improve, b) Leave as-is, c) Consolidate, or d) Remove. I give you the free template to download in this handy swipe file below!


2. Information Architecture (IA) Review

Review your IA at least once a year to ensure that users and search engines alike can effectively find their way around your site. An IA that’s good for crawlers will be efficient when it comes to click depth, horizontal breadth, internal linking, keyword optimization across levels, and URL structure. An IA that’s good for users will take into account things like intuitive navigation and ease of use.
