You’ll then access an actionable, comprehensive list of on-page or sitewide SEO elements to add or improve, such as keyword density, links, and technical bits like XML sitemaps or Robots.txt files.

The SERP overlay feature reveals important data for the entire SERP and for individual results. Like keyword difficulty (how hard it is to rank in the top 10 results for that keyword), which appears directly under the search bar. And backlinks (the total number links to that page from other domains).

You can unlock even more data if you connect SEOquake to your Semrush account. 

For example, you can review Authority Scores (a measure of how high-quality a website or webpage is), average pages per visit, and average visit duration. 

From SEOquake toolbar, you can click on “SEMrush rank” to pull up Semrush and find more relevant information.

The extension lets you check the status of various technical elements.

These include elements like schema and redirect chains, which are important to monitor for the technical optimization of a website. 

There’s also an export feature for many of the same elements, such as links, which is useful for checking your internal linking strategy or ensuring external links are do-follow—which are more valuable for SEO. 

The extension includes seven distinct tabs dedicated to different helpful data points, including: 

  • Overview tab, which includes items like the title tag, meta description, URL, meta robots, and Google core web vitals.

  • Status tab, which shows status codes for web pages. Some of the most common status codes include 200 (OK), 404 (not found), or 502 (bad gateway). If the status code of a website shows you an error, you know something is wrong with the page, server, or something else.
  • Images tab, which breaks down images on a page into two groups: those with alt text and those without. It’s important to include alt text to make images more accessible for users and search engines alike.

Why do they matter?

Because they help audiences all around the world access the content that’s most appropriate for them. Meaning they matter a lot for international SEO best practices. 

For example, if you create alternative versions of your English-language blog in Spanish and Portuguese, you can use hreflang tags to ensure readers in Argentina and Brazil are served content in their languages.

Hreflang Tag Checker helps with these types of workflows. It works by crawling a site or page’s language attributes and hreflang architecture—making it significantly easier to audit your site’s suitability for success in all your target languages, fast.

10. SEO META in 1 Click

The Images tab is useful for flagging any images on the page with missing alt text. While the links tab compiles all of the links on the page into one list for quick reference.

Finally, the Tools tab links out various third-party tools where you can check things like mobile-friendliness, page speed, or CSS elements. 

This matters because pages with bad mobile-friendliness or page speed scores—or misfiring CSS elements—could degrade user experience.

11. View Rendered Source

View Rendered Source lets you quickly check the difference between a page’s source code and the rendered (i.e., constructed) version in a browser. 

From an SEO and web development perspective, this is useful for both debugging issues and making improvements to elements that impact page speed or the way search engines interpret your page.

Remember: technical SEOs and web developers often need to understand the way a browser renders pages. Poor rendering can have an impact on both User Experience and search engine visibility. 

View Rendered Source does this by illustrating the way a browser renders a page’s source HTML into a Document Object Model (DOM). It also shows any modifications caused by JavaScript.

Because of this, View Rendered Source is a handy tool for developers or technical SEOs working on sites powered by JavaScript frameworks, such as:

  • Angular
  • ReactJS
  • Vue.JS

  • Keyword competitiveness score
