You can use it to check whether a specific page meets the relevant criteria for a good ranking on Google and other search engines. You will receive a clear list of the problems found and the optimization potential of your site in terms of meta information, page quality, page and heading structure, external and internal links, and much more. This allows you to perform an in-depth SEO analysis for each page of your site.

Keyword Checker

The Keyword Checker analyzes how well your page is optimized for a specific keyword or combination of keywords. You can use the Keyword Checker to optimize your website for the keywords that are most relevant to your business and thus achieve a better ranking in search engines. Optimizing for keywords and topics is one of the most important tasks when optimizing your website. Not only will the search engines reward you with better rankings, but your visitors will also have a much easier time finding the information they are looking for.

Backlink Checker

Backlinks are still one of the most important factors for a good search engine ranking. Seobility's free Backlink Checker gives you a detailed overview of your website's backlinks, either for a specific subpage or for your entire domain. You can also use this tool to analyze the backlinks of your competitors to get ideas for your own link building.

Redirect Checker

The free Redirect Checker verifies that your website redirects correctly to a uniform URL version (with or without "www" in the URL, or to "http" vs. "https"). If there are errors here, this can lead to duplicate content problems on your site, which can have a negative impact on your search engine rankings. The tool also generates the necessary code for Apache and NGINX servers to set up correct redirects.

SERP Snippet Generator

Analyze any URL with Seobility's free SERP Snippet Generator to find out how it appears in Google's search results. If your meta title or meta description exceeds the recommended length in pixels, you will receive a warning here. You can adjust and optimize both elements directly in the tool until they reach the recommended length to achieve an optimal display of your website in the search results.

The TF*IDF tool helps you optimize your text content for search engines. It checks which important terms are frequently used on the top-ranking pages for your target keyword. Based on this, you will receive recommendations on which terms you should use more or less frequently in your texts in order to achieve an optimal term weighting according to the TF*IDF formula. With the integrated text editor, you can edit your content directly in the tool and watch how the recommendations are automatically updated!
