SEO success is difficult in the current competitive online market, so how do you get ahead? Doing regular SEO audits of your site can give you a proven edge over competing websites.

What Is SEO Audit Software?

An SEO audit is the analysis of your website based on several factors that search engines find crucial. Successful SEO audit tools dive into three main areas to identify issues and opportunities and give you suggested fixes. Please note that most of these platforms are comprehensive SEO suites, but the purpose of this article focuses only on their auditing functionality. You may also be interested in our overall review of SEO software and their offerings as a whole.

  1. Technical infrastructure – comprises how your webpage is setup as far as title, headings, paragraphs, links, images, video, type of code (HTML version) used to generate the page, etc.
  2. On-page analysis – elements that can be optimized on the webpage itself – typically relates to the technical infrastructure above, i.e. use of headings, image alt tags (an “alternative” accessibility feature to describe the image for those that are unable to visually see it), etc.
  3. Off-page elements – anything that is not within the control of the webpage itself, but influences the page from the outside. This can include social media, backlinks from other sites, mentions of your brand name, etc.

We chose SEMrush as the best SEO audit software for its all-in-one suite of auditing toolsWe are active users of the Site Audit feature in SEMrush. It does an excellent job of finding on and off-page issues including broken link checking, duplicate content warnings, content length suggestions and finding slow loading pages. In the audit portal, SEMrush highlights major errors that need to be addressed immediately and allows smaller concerns to hide in the background. Fortunately these are easy to navigate to.

Ahrefs Review

#2

Visit Website

Ahrefs has a strong reputation for its off-page SEO auditing, but it also has one of the most potent site crawlers on the market to identify and resolve technical and on-page issues.

The site audit interface is similar to SEMrush. Major issues like missing headers or meta descriptions are flagged clearly and then the user can drill down to less important issues like image errors.

Pros

Cons

  • Integrates with Ahrefs backlink index, which is the largest the industry
  • 100+ pre-configured SEO issues
  • Recurring crawls can be scheduled
  • Data Explorer allows you to create custom filters based on many different parameters
  • Takes time to learn
  • Does not find AMP implementation issues

Pricing

Ahrefs offers a 7-day trial for $7 for its Lite and Standard plans. You can save 20% off the following prices if you pay annually.

Screaming Frog Review

#3

Visit Website

Unlike SEMrush and Ahrefs, both of which are web-based solutions, Screaming Frog is software that runs on your computer. Screaming Frog’s SEO Spider is arguably the best tool on the market for technical SEO audits. SEO Spider is a robust, flexible site crawler that gives you the ability to analyze in real-time a massive variety of technical and on-page SEO data for sites of all sizes.

Where Screaming Frog differs from the other tools mentioned is instead of a visual Site Audit portal, it simply provides all of your site data in one massive spreadsheet. So everything you can imagine – Titles, Metas, Headings, Inlinks, Outlinks and more, are all right there at your fingertips. This spreadsheet is not for the faint of heart and is better to be analyzed by an experienced SEO advisor.

Pros

Cons

  • Free SEO Spider version
  • Configure for multiple data sets
  • Get all of your site’s data in minutes
  • Ability to collect data from the HTML of a web page using CSS Path, XPath or regex
  • Annual site license is limited to one computer
  • Cap of 500 URL crawls with the free version
  • Recurring crawls cannot be scheduled
  • Not web-based and software uses a lot of memory/hardware resources

Pricing

UK-based Screaming Frog offers a free version of SEO Spider, capped at 500 URL crawls.

  • £149.00 (approx. $216) for 1 annual license

SEO Tools That Take You Far Beyond Auditing

If you are already using SEMrush or Ahrefs for other SEO purposes such as Backlink Analysis, Keyword Rankings, or Keyword Research, we believe they are similar enough that you can just stick with what you currently use. If you are not using either service and are looking for the most economical Site Audit solution (since both tools start at $99 a month), Screaming Frog is an excellent value at £149 a year.

SEO auditing software is essential to improving your site’s overall performance, but many SEO tools on the market go above and beyond auditing analysis.

Be sure to read our best SEO tools article, where we review more than a dozen top-rated SEO software options. Some tools specialize in specific SEO areas, while others provide a more comprehensive suite of SEO analysis tools.
