Up until circa early Feb my serps in 5 search engines were approximately the same. And they remained the same with the exception of Google where many pages started to drop down the rankings from Feb onwards.
They are now popping back up again.
I only monitor page one results.
I decided to check TWO websites only; and this is what I found:
Of 9 pages in total examined at random, 7 had identical positions in Google and Yahoo; and of the remaining two pages, one page was one position adrift, and the other 4 positions.
IS THIS ALL AN INCREDIBLE COINCIDENCE?
Or does it signify another major algo change by Google,retreating perhaps to their pre Feb algo, or something similar?
What are you experiencing with your sites?
