I noticed a strange ranking drop in google. I checked a site for a particular keyword phrase and it was ranked in the first page - 10th position. I was using a link to this page as signature in a popular forum and was replying to a few queries.
After a couple of answers in the forum, the page dropped to second page (13th position).The forum page was indexed by then. Google usually indexes this forum very quickly.
I tried the same to another page (a different site) and I noticed a similar fall. This page was in 10th position for a particular keyword phrase. After adding the links, the page immediately dropped to 2nd page (11th position).
The only difference in the second instance was i didn't use the keyword phrase to link back.
Has anyone noticed this phenomenon before? Very strange.Why does google do this? So does a page dance before it settles down, after a link back to it?
