What are SEO Auditing Tools

SEO auditing and monitoring tools let you check and maintain your on-page SEO standards. Affiliate marketers, with their dependence on Google search and SEO, should closely monitor their sites health with these free tools.

The tools range from website-based performance analyzing tools — to pc&mac applications that will do a complete site crawl and technical analysis. We did not include paid tools like Ahref or SEMrush – they also have some analysis tools for doing site audits. Nor did we include tools like WooRank which requires a credit card for the trial (though WooRank is a great tool). There are lots of tools in this area. We looked at scores and these came out as our favorites.

So if you are an affiliate or blogger looking for a free SEO checker or a free SEO report read on!

These are free tools – some people just can’t justify $1,200 a year for premium tools. Budgeting-wise $99/mo here, $79/mo there can really add up quickly. That money may be better spent on content or outreach.

Why Audit?

Auditing is your way of testing your site for compliance and quality with Googles standards as well as industry best practices.

Google is essentially auditing on every crawl. Your new articles are ranked based on performance and on-page quality.

What Matters for SEO

It all matters.

Somethings uncovered in an audit likely matter more than others. Heavily weighted on-page optimization items include; performance, mobile support, links and more. Here’s a really great infographic that will help understand weighting factors.

These tools are great for finding technical SEO issues. They will crawl your entire website, check each page and post for tags, meta descriptions, attributes etc. Some will also help with keywords and report backlinks and internal linking and structure.

These are the most widely used general purpose audit tools.

Screaming Frog SEO Spider

This does a very thorough audit and provides its findings. It will show the usual tag status but also a backlink profile and Moz score.


Lipperhey also adds keywords and competition to its auditing and analysis tool. It does a very deep scan of your site and will take a few minutes. It reports all status code issues and meta descriptions as you would expect. One Interesting feature was the link distance. It is good to know if your content is orphaned from the navigation menus. They provide the usual analysis plus an SEO overview. Pages are ordered by importance to the site and their SEO “health” — nice feature.

 Neil Patel SEO Analyzer

Neil Patel is hard to ignore given his success. His SEO tool provides SEO score, Speed Score, Backlinks and Pages Indexed. You can get much more information from something like Lipperhey but a visit to Neil Patel’s sie is always a worthwhile trip.


SEOmator had the usual reporting on structure, header tags and meta description, 404’s etc. But one interesting analysis was Content Quality. It reported the content by page length and checked for duplicate content.

Varvy’s SEO Overview Tool

free online SEO audit tool, One thing that Vavry identified, that other tools did not, was a lack of inter-page navigation for some parts of the tested website.

A good datapoint overlooked by others.

2 — Site Speed and Mobile Responsiveness

The performance tools are all about your site speed and mobile experience. Google seems to be putting more and more focus on site performance. You really should be loading in under 2-3 seconds. Mobile is a continued priority. You also should benchmark the site at Google PagesSpeed Insights as discussed below. Best to ignore any scores and focus on things suggested that you can fix.

GT Metrix

GT Metrix is one of the go-to sources for testing your site’s performance. It tests similar items to Google PageSpeed though often different results.

The waterfall feature helps you see where you have delays in your site loading.
