Best SEO Audit Tools To Boost Your Website’s Performance

Site audits are serious business and should not be taken lightly. Day in and day out, you need to put in a lot of effort, which takes time and energy. A careful eye is required as the auditor must review numerous pages. 

Several products have recently entered the market, simplifying the tasks of SEO auditors significantly. Performing manual checks on every web page is not labor-intensive for auditors. There are hundreds of websites out there that offer audit tools to help you find the issues on your site. Using website SEO audit tools is an excellent first step, but more is needed to find and fix bugs in your infrastructure. It would help if you supplemented a professional auditing team to get results that pass muster.

In SEO, what exactly does “ranking” refer to? 

Seo, or search engine optimization, is a method used to raise a website’s visibility in search engines. Let’s be honest, though; that word has been replaced by Google in modern parlance. Your content’s rankings are based on how well you’ve optimized it (SERPs). If you optimize your website for a specific phrase, it will appear at the top of Google search results for that term, above sponsored results, featured snippets, and answer boxes.

Factors To Consider Before Choosing An SEO Audit Tool

  1. Crawlability

Search engines can’t index a site’s content if they encounter errors, broken links, or improper redirects at every turn. Take some basic precautions to guarantee that the bots will have unrestricted access and can crawl your site without any problems. 

  • Verify that all URLs are complete with a 200 OK status. 
  • Make sure canonical URLs are correctly set. 
  • Make sure every URL can be easily indexed. 
  • Verify that there are no broken links in the cited resource list. 
  • Check that every page loads correctly. 
  • Check to see that each page loads quickly enough. 
  • Verify that all URLs listed in the XML sitemap are valid and can be accessed without problems. 
  • Verify that every redirected URL succeeds in reaching its intended destination. 

Easy enough? On the other hand, crawlability may seem like a piece of cake, especially for larger sites. It’s essential to take extra care to avoid these frequent aches and pains that can hinder crawling: 

  • internal links that are either subpar or nonfunctional 
  • site architecture that isn’t optimized for search engines 
  • Problems with the server 
  • redirections that loop 
  • Invalid JavaScript 
  • inconsistencies in the script 
  • If you run through this checklist first, your technical SEO site audit should go more smoothly from here on out.
  1. Indexability

Getting the site crawlable by search engines is priority number one. However, things will return to square one if they cannot accurately index the content they crawl. 

You can make sure the content is easily indexed by fixing the problems that could prevent indexing in the first place: 

  • 500 server-side errors 
  • There were 5xx server errors, so the server refused all URL requests. 
  • Misuse of nofollow tags 
  • replacing CSS-based site navigation with JavaScript 
  • repair of critical broken pages after a hacking attack
  • standard error pages
  1. Rankability

To rise in the search engine results pages (SERPs), you need to have high-quality content optimized with ranking factors that are more powerful than your competitors. 

While Google has disclosed using over 200 ranking factors when evaluating the content, the most important ranking factors for technical SEO are content and links. When these two peak performance, there is little else to worry about. 

Content analysis, keyword optimization (or lack thereof), and how user-friendly and effective the site structure is should ideally be examined during the audit. How thoroughly this is reviewed will depend on the scope of the project.

  1. Page Speed

Since 2010, Google has used page speed as a ranking signal for desktop searches; in 2018, the search engine giant began giving equal weight to mobile page speed. Nobody likes to wait for pages to load, whether on a desktop computer or a mobile device. 

This is why conducting speed tests on your pages during the audit and periodically afterward can help you catch potential sluggishness issues before they become performance issues. This is where Google’s PageSpeed Insights come in. 

  • GTMetrix
  • Lighthouse 

Put URLs through your preferred page speed testing tool thrice to ensure rapid loading times. 

  • Consider the results of each of the three scores. 
  • To find the average page speed, run all three tests.
  1. User Experience

Even though the user experience isn’t typically used as a ranking signal, it can significantly impact sales. Sites with a brilliant, user-targeted color scheme, compelling calls to action, and a cohesive design are more likely to convert visitors than sites with dull, disjointed designs. 

Equally important is uniformity. Your website will only succeed if it provides a superior mobile experience but a subpar desktop one. You can get a good idea of how user-friendly the client’s website is by checking out Google Analytics metrics like bounce rate and average time on page. 

In addition, heatmap tools like Crazy Egg, Mouseflow, Lucky Orange, and can provide invaluable insight into the behavior of the site’s intended audience as they interact with the site’s content.

  1. On-Page Optimization

Though higher positions in search results for less-competitive keywords can be attained relatively quickly, doing so for more competitive keywords requires more time and work. Does the site use standard on-page optimization strategies? 

For best results, check that the technical SEO audit covers some fundamentals of on-page optimization. 

  • the use of relevant keywords in headings, page titles, and meta descriptions (H1, H2, H3, etc.) 
  • to keep up with relevant searches, at least enough content 
  • References to other reputable online resources 
  • to relevant internal pages 
  • performance enhancements in the source code

SEO is getting more competitive, but all the tools available to site owners make it easier to ensure you do everything to optimize your site. Test out some of the tools in this guide to see what works for you. Many provide the same features and can even be used together. But everyone has preferences for design and workflow, so you may find some to be a better fit.


Are SEO Audit Tools Worth it?

SEO audit tools help you analyze important SEO factors to ensure the best possible rankings for your site. Many factors impact SEO, and SEO audit tools help you check them more efficiently. Some of the most common factors analyzed by a good SEO audit tool include:

  • Track crawlability to make sure that Google can find your pages.
  • Analyze metadata and page titles
  • Check for broken links
  • Find duplicate content
  • Ensure pages aren’t blocked by robots.txt
  • In addition to reviewing your site, SEO audit tools quantify what they find, making it easier for you to understand the overall health of your site.

Plus, the best website audit tools integrate with other crucial platforms like Google Analytics, and you can automate and schedule your crawls in advance.

What is the difference between manual and automated SEO tools? 

SEO audit tools are not the only way to check your website’s SEO health. Many site owners choose to conduct a manual SEO audit, and SEO professionals typically do these with an extensive understanding of all the necessary SEO factors.

While Automated SEO audits can be done much faster than manual audits, the latter has several benefits. With a manual SEO audit, an SEO professional will check many of the same elements in an automated audit, plus factors that software can’t test.

For example, an SEO professional can review how human users experience a web page. User experience will ultimately affect how well users engage with your pages, and thus it impacts your search rankings.

What kind of information can an SEO audit tool provide?

An SEO audit tool can provide a wide range of information, including metadata analysis, content analysis, keyword analysis, backlink analysis, site speed analysis, mobile-friendliness analysis, and more.

Are SEO audit tools expensive?

The cost of SEO audit tools can vary widely, from free tools like Google Search Console to premium tools like Ahrefs and SEMrush, which can cost hundreds of dollars monthly. Evaluating your needs and budget before choosing an SEO audit tool is important.

How often should I run an SEO audit on my website?

The frequency of SEO audits can vary depending on your website’s size and complexity, as well as your resources and goals. In general, it’s a good idea to run an SEO audit at least once per quarter, but some websites may benefit from more frequent audits.

Can I perform an SEO audit without an SEO audit tool?

While an SEO audit tool can save you time and provide more comprehensive insights, it’s possible to perform an SEO audit manually. This may involve reviewing your website’s metadata, content, and backlinks, analyzing your competitor’s websites, and conducting keyword research.
