Typical Lazy PHP Programmer

That’s me, write a program and it works, don’t bother initializing variables, etc. That was until I moved to a new host that had display errors turned off. It is pretty much impossible to debug without errors being displayed so I went rummaging around for ways around this and found the following code:

Return of Pages Indexed and Link Quality Tool

A popular tool on the old Eixir site was the pages indexed and link quality tool. When we changed sites we lost those tools but we have now recreated them with some more bells and whistles at http://www.semreportsonline.com/

This site is still in beta (or even alpha) but I wanted to open it up for people to play with and give feedback.

Main features:

  • Link quality assessment including graphs and history functionality
  • Pages indexed across all 3 major engines.
  • Ranking reports including capability to go back in time and compare ranking reports including how the top 30 looked at the time.
