Mayday: how Google May update will affect your long tail rankings

In an online forum, webmaster discussed their experience with Google latest ranking algorithm update that has been given the name Mayday. If your website gets fewer visitors from Google, the update could be the reason for that.

What exactly has happened?

Many webmasters have seen a huge drop in traffic from Google for keyword phrases that are three or more keywords long (so called "long tail keywords").

Some webmasters have lost 90% of their traffic from Google because they cannot be found anymore for the long keyword phrases.

The ranking drop did not happen to spammers. Among the affected websites was a 13 year old site with a Google PageRank of 7 and 400,000 backlinks.

Why did it happen?

It seems that this is not a penalty but a change in Google's ranking algorithm. Google might now be able to index longer keyword phrases more accurately. There's a new Google patent that deals with this topic.

Identifying phrases requires a lot of computing power and a lot of memory. A webmaster explained it in the discussion:

"For example, on the assumption that any five words could constitute a phrase, and that a large corpus would have at least 200,000 unique terms, there would be approximately 3.2.times.10.sup.26 possible phrases.

Clearly more than any existing system could store or otherwise programmatically manipulate."

It seems that Google guessed the best pages for long keyword phrases until recently based on other signals and keywords on the indexed pages.

The new Google patent indicates that Google now has the computing power to index longer keyword phrases on web pages instead of guessing them.

Do you have to change your web pages now?

If you experienced a decline in traffic to your website from Google you might have to change your web pages. For example, if you want to be found for "personal injury lawyer london" then these words should appear in that order on your website.

If you use other variations such as "london lawyer personal injury" then you'll probably get listings for that variation but not for other word combinations.
