The best SEO audit tools for website crawls, keyword research, and more.
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
- 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.
Our picks for the best SEO audit tools
Below is a list of our favorite SEO tools, including the ones we use for extracting some of the most fundamental data for our Visibility Audit. We’ve listed them alphabetically, noting the current costs (as of December 2020) and the areas of SEO listed above that each tool will help address. In some cases, such as page load speed, we found that different tools can give you a different view of the problem, so using more than one is vital to really understanding your website’s performance. Please note, this is not an exhaustive list; but we’ll keep it up to date as we discover new SEO audit tools that we use and love. We hope the tools on this list helps you gain a better understanding of your website’s performance. Happy Auditing!
