The screen shot is something i watched in a video tutorial but i cant replicate it on a PC. Basically fro SEO purposes I want to investigate the HTTP status of chosen urls. I can see there is a curl -I -L www. thing going on but is this:
Command Prompt on a PC
& secondly nothing seams to work
Any insights welcome
Windows has completely different commands than Linux. You will need to figure out what the equivalent of curl is in windows if there even is one. The Windows command line/bash is not nearly as useful or easy to understand as the *nix one. In short it is much easier to develop on *nix platforms except for .NET. You could also try the powershell on windows which might be a little more user friendly.
From an SEO perspective this is OK because its simply pointing the non secure to the secure? Or is it a problem. I read that 301 can be problematic because they slow down sites and can confuse bots (so i read)
I also use this https://tools.pingdom.com/ as sometimes even if you have a page correctly returning (200) you might have missing files or linked files that return other codes and this will show problems in the waterfall.
The Google Search Engine tool can only be verified by uploading a verification HTML page or inserting supplied verification script into a web page header. Once verified the owner can invite others to read-only share results but they are not able to change any parameters.
You can also check the http_response_code here for http, http://www, Https and Https:/:www to ensure the .htaccess script is set correctly:
