SEOquake is a browser plugin that can assist users in SEO (Search Engine Optimization). The plugin shows users different SEO metrics and analysis values for the websites they visit, thereby offering them the opportunity to evaluate the SEO performance of their own or other websites.

Some of the metrics that SEOquake can display include the number of links that point to a website, the domain authority (a measure of the quality and trustworthiness of a domain), the PageRank (a ranking system from Google that assesses the relevance of a page to a particular query), and many others.

SEOquake is particularly useful for webmasters and SEO experts who want to monitor and improve the SEO performance of websites. The plugin provides users with a wealth of information and analysis values that can help them understand the strengths and weaknesses of websites and make appropriate optimizations.
