SEO Tools

SEO tools of SEO Deutschland

SEO tools require all those who have ambitions in the SEO field or want to try their hand at SEO. Even specialists like us, appreciate the help of some SEO tools!

Many of these SEO tools are available as extensions for the browser (usually Firefox), while others can be accessed and used on a URL.

Despite my own positive experience, I do not want to put any of my recommended SEO tools above other freely available tools. For one, there are so many different tools that I can not even know every one. And on the other hand, I believe that every SEO has its own experience with SEO tools and that one gets very used to the operation of the tool and the form of the result presentation over time.

Header Checker

Search engine optimization finds its application already at the first exchange of information between server and client (browser). The header checker gives you information about the issued HTTP status code of your domain. Essentially, it is only about the forwarding of the subdomain “www“.

The well-known “www” is basically just a subdomain. Similarly, one could also use “iii” or “mmm“. The average Internet user got used to the spelling of a URL, with “www” at the beginning. That’s why every traffic-endeavoring site operator must also be able to access his domain via the subdomain in addition to the actual

In addition, Google treats subdomains as separate domains. In order not to run the risk that your site will be punished because of “duplicated content”, an HTTP status code 301 should be issued. The HTTP status code 302 (moved temporarily) should be avoided as far as possible.
