Hey all, So for the past few months i have been setting up and running several case studies to help understand Google and because it is part of my job. For all that would be interested i have a website that has been ranking well and doing out it has a good diverse range of backlinks all whitehat around 500-1000 links in all, its a smallish site nothing massive. about a 3 months ago i was ranked #10 for the term 'UK Fitness Blog' i decided to try a case study and see what blog rolls would do for a site. I got a blog roll link off of a fitness independent blog with a DA of 29 and a PR of 2. After the link went live my rank dropped to #21 this was a day or two later. I left it there for 1 month to see if anything would balance out but all that happened was it jumped around #20-30 then just sat on #21 i then contacted the owner and got removed from the blog roll and it took a while but i am now at #9 i have received some natural links from people from then which would explain the #10-#9. Now i decided when i started this that i wanted to try and do the same thing but on another site so i ask someone i know if they could do it at the same time as a test we both carried out this audit at the same time making the same changes, his blogroll was from another domain that was i belive DA 41 and PR 3 he had the same results for his keyword (different niche) was ranked #11 and had been there for a few months, after the link the ranking dropped down to #18 and bounced around that number. This case study has shown me that blog rolls and sitewide links don't seem to do anything for a website apart from harm it, i would like to know other peoples experience with this to see if there is any different results. Thanks, Hope this helped some people. Killix.
