The best SEO audit tools

A few of our favorite things: the best SEO audit tools

Whether you are preparing to redesign your website, or wondering how to improve the quality and quantity of its traffic and leads, an SEO audit is, hands down, the best mechanism for understanding its true effectiveness. You’ll be able to tell what pages are your shining stars—bringing in the most engaged visitors—and pinpoint problem areas that you can address to boost performance even more.

No one SEO tool does it all

An SEO audit, though, can mean different things to different people, including your web developers, digital marketers, and SEOs. At Pure Visibility, we found there was no one audit product on the market that gave us the complete picture we were looking for, so we developed a method we call a Visibility Audit. Think of it as a super-charged SEO audit service that analyzes a company’s digital visibility across the internet, with the website at its core.

Through our process of developing our Visibility Audit, we worked with dozens of online SEO tools to find the right combination of data points we needed to perform our analysis. Some of the tools we had already used for years, while others we discovered while looking for more efficient ways to get the job done. Either way, it was hard to choose from such a robust field of SEO applications, both paid and free.

Fortunately, these tools are readily available to anyone, and almost all are web-based applications, many with freemium pricing models. Each one can help you understand a piece of the inner workings of your website, but to really figure out what’s going on, you need to find the right combination for your needs. When analyzing any website’s performance, we recommend the following seven areas as the minimum to be evaluated:

  • Keyword rankings
  • Traffic (volume and behavior)
  • On-page SEO
  • Backlinks
  • Mobile-friendliness
  • Page load speed
  • Technical SEO (crawlability, indexability, and code issues)

Depending on your market, business model, and goals, you may hone in on different aspects to weigh more heavily than others. But, we have found that leaving any one area out entirely can lead to a fairly significant gap in your understanding of your website’s performance.

The best of the best: Our top 4 SEO audit tools

If we had to pick the SEO audit tools that we could not live without, we’d choose the following because of the sheer quality of data they provide. None is a one-size-fits all tool, but each is invaluable to gaining the level of understanding we need to perform our SEO audits.

  • Ahrefs – Logo for Ahrefs backlink audit toolOur favorite for reviewing broken backlinks and overall domain profile. Also great for performing keyword research, with alert options for keywords and brand mentions. This tool offers valuable insights on a page-by-page level so you can improve your own performance while also scrutinizing the competition.
  • Screaming Frog SEO SpiderLogo for Screaming Frog website crawler toolA desktop-based software, ScreamingFrog is the industry standard when it comes to website crawling. Offers a thorough analysis of SEO elements—its page-by page review is second-to-none, and the level of detail provided is especially helpful for identifying opportunities to improve on-page optimization.
  • Google Search ConsoleLogo for Google Search ConsoleThe best big-picture overview of your website pages in terms of indexation issues, organic performance metrics (impressions, clicks, click-through-rate), and sitemap issues. Other tools may be better for deep-dives into specific issues, but GSC gives you insight into overall patterns and opportunities and, best of all, comes straight from Google itself.
  • SEMrush –  Logo for SEMRush audit toolBest for evaluating a website’s domain history, including keyword rankings and estimated organic traffic, layered on top of known Google algorithm updates. This allows you to gain insight into how certain updates may have affected your visibility. SEMrush also allows you to not only perform in-depth site audits, but also track and compare progress so you can evaluate how changes to your site improve its performance over time.
