SEO investigate HTTP server responses

in SEO

As of 2014, there are plenty of tools that allow observing HTTP traffic from and to your browser. As a default, nowadays browsers come with an integrated Developer Tool offering that – among many things – offers a visual interface for such tests. Why is valuable investigating the HTTP connections? From an SEO standpoint, this investigation proves to be helpful while debugging Ajax problems and Flash apps connectivity issues. Similarly, it may be necessary to investigate the cause of a redirection chain, or the HTTP response returned when users hit a resource. It is not a surprise (not anymore) the fact that many sites – although very expensive – have many underestimated technical issues simply because coders have no clue of what the web and the Internet foundations are.

The “diff” in SEO: how to use the *nix command

in SEO

When it comes to debug a web site, no matter what the reason could be (e.g. hacked web site or just to check what changes have been done), another useful command offered by the *nix is the Diff command. In a nutshell, the diff command is typically used to show the changes between one version of a file and a former version of the same file.  I don’t want to enter into minutia explaining every sort of option this command line tool offers, rather be extremely practical and help you to get the most from your comparison process. The only prerequisite is you to have the file locally saved somewhere, preferably in the same path so to avoid twisting along the command line and the file path.
