Whatever you're doing, whether it's analyzing a new client's site or analyzing marketing prospects, you can use one of the many free SEO tools. Below is a list of what I think are the best programs and extensions that will make your SEO report or presentation even clearer and more informative.

1. Check Server Response Status Tool

free seo redirect checker

Provides data on server response status of the given URL, by delivering all technical details of the request like the HTTP headers and redirect chains catching both 302 and 301 redirect codes. 301 Redirection is used to provide permanent redirection from irrelevant domain address or a URL address of a separate page to the current address of the relevant content. Redirects may be required in case of a global migration of the site to another domain, or technical changes in the website's routing system, removal of pages, change in internal and outbound linking. One of the options for using of the permanent redirects - redirection from multiple CCTLDs to one main domain. Proper redirects allow you to move content without any losses of your relevant organic traffic, keep and even increase the previous search engine rankings.

2. Check Page Resources Request Flow

free SEO page load waterfall checker

Delivers details of the page resources request flow during initial page load. The tool provides 100% details of the page load requests run by the new Googlebot Evergreen environment by executing Chrome browser engine server-side.
Current resource load checker tool extracts the most important information about each request triggered during the page load, such as server response status code, response headers and the size of the requested resources. For most sites, page load process involves dozens of external resources, and most of the loading time is spent on various HTTP requests for images, JavaScript files and style files. AJAX may help, but speeding up or removing those HTTP requests may be much more helpful, although there is no common approach on how to achieve it. Reduce the size of HTTP requests. Often cookies are set for the entire domain, or even for all subdomains, which means that they will be sent by the browser even when you request every single picture from your site. This can turn a 400-byte response with a picture into 1000 bytes or more, depending on the added cookie headers.

3. Parse Source and Rendered HTML Head Elements

HTML Parser tool extracts the two versions of the HTML < Head > section: from the source HTML document and from the rendered DOM (i.e. Browser Elements section).

This free SEO tool helps to identify whether there is different information provided for the same HTML elements in both code versions that may confuse the search engines. Document Object Model (DOM) is a collection of nodes or pieces of information organized in a hierarchy. This hierarchy allows the developer to move through the tree in search of the desired information. Structure analysis usually requires that a complete document be loaded and the hierarchy be built before work begins. Because DOM is based on a hierarchy of information it is called tree-based or object-based.
