All of these updates can help you improve overall SEO performance and generate positive results.

Screaming Frog SEO Spider

Screaming Frog SEO Spider isn’t the same as the other SEO auditing tools that we review here. This tool isn’t based on the cloud and comes with an installable variant, which can be installed on your system.

After it is installed, the tool runs through your website, extracts all on-site data, and analyzes the results on a real-time basis. During the crawling process, the tool finds out all SEO discrepancies in real-time and prompts you into action.

All digital marketers and SEO auditors can use the Screaming Frog tool to improve their SEO results and scrape away irregularities in the form of broken links, blocked URLs, redirects and poor meta’s.

Google Search Console

Google Search Console might sound new to you, but it is the same as Google Webmaster Tools. Google Search Console is a renamed version of the Webmaster and offers the same performance that SEO experts had come to experience from it.

The Search Console by Google is fairly reliable since it comes from the horse’s mouth and can help give you directions laid down by Google itself.

The Webmaster comes with refined capabilities and can help you go back in time to find data from almost 15 months ago and audit it for you.

Once you perform an audit, you can run across the section for insights on the platform and get an idea of the accessibility issues, along with indexation problems faced by most SEO users.

Google Search Console can also go beyond the ordinary to help provide you with details on HTML, broken links, quality issues, HTML and a lot more.

Features of Google Search Console

Google Search Console comes with a number of features that help differentiate it from other tools. These features include:

  • Google Search Control can help test, track and monitor all of your AMP pages.
  • The search console by Google can help crawl your pages and identify any shortcomings present across them.
  • Google’s Search Console can point out all failed attempts at indexing and other pages with multiple errors on them.
  • The console comes with a unique tool for analyzing your keywords and assessing their performance.

The website comes with a Rank Tracker for tracking your rank and related data, a Content Explorer for exploring flaws in the content, a Keyword Explorer for finding out flaws within your keyword, a Site Explorer for auditing your site and a final Site SEO audit tool.

The Site SEO audit tool is the most comprehensive of all plans offered by Ahrefs and is basically where you can get the best results possible. The site auditing tool gives you clear directions on what is required for clearing the external pages on your website, including CSS and JavaScript resources.

The tool can also highlight articles with a low word count and those missing social tags, so that page-specific performance issues are solved appropriately.

Ahrefs Features

Ahrefs is very similar to SEMrush in the features that it brings. Some of the core competencies and features include:

  • Crawls through both desktop and mobile versions of your site to give you a unique experience.

GTmetrix is different from all of the previous tools we have discussed in this article because it is more of a testing tool than a crawler to run through your web pages.

The tool can look over all of your web pages and give you the insights you need into the technicalities and operations of your website.

The tester by GTmetrix does take a few initial seconds to get running, after which it will give you actionable insights into the size of your pages, the loading speeds of different pages, and how it ranks across different parameters, including image scaling and caching.

The testing tool by GTmetrix can help give you insights into 25 different factors related to SEO. Website owners and SEO experts can utilize these factors to find out problems within their website and how the problems are negatively impacting the website’s performance.

GTmetrix Key Features

GTmetrix is different from the other best SEO audit tools in this article because it primarily operates as a testing tool. The key features of this tool include:

  • The different metrics are displayed in an actionable format to help you find areas where you can improve.
  • Loading issues are highlighted and minimized.
  • The web performance of your pages is replicated on over a dozen devices to see usability across devices.
  • The platform uses graphs and charts to display information.
  • User experience is highlighted.
  • All web pages are gauged through Google’s Lighthouse
  • Page performance is recorded from 20 plus diverse locations.

You can get over 50 on-demand tests on GTmetrix. Increasing this limit to 150 or plus would require a minimal monthly payment.

SE Ranking

SE Ranking comes within the same category as Ahrefs and SEMrush, as it provides a full blend of SEO tools and services. The tool is heavily focused on-page analysis, website auditing, keyword auditing and link tracking.

SE Ranking crawls through each link on your website to give you an indication of user experience and assess your website for SERP, image optimization and headers.

Features of SE Ranking

Some of the features of SE Ranking include:

  • Can gauge all your web pages
  • Identifies all SEO errors based on your defined metrics
  • Offers tips on how to solve issues with SEO
  • Analyzes all internal links
  • Compares different SEO and website audits to help track your progress

SE Ranking comes with a basic plan of $31 per month, with rates for premium plans going upwards.

Almost all of the tools we have discussed and featured in this list come with their own tools and unique attributes. These attributes define them and separate them from the rest. As an SEO expert or a growing business, you should harness the potential of multiple tools at one time.

Combining multiple tools together will help you achieve better SEO results and audits. Almost all of the tools mentioned here do come with a free version as well, which will help you test them without paying anything upfront.
