Hi,
this post is a bit OT, but the conclusion is about Google Ranking, so...
has anyone noticed that now the adwords real destination url is displayed when you move your mouse over ads and u keep the left button pressed without releasing. Usually u would have seen the redirection url of google, now it's without it. In HTML source you can find the real code with redirection, but there is a function that make it disappearing.
Now I am guessing why it's there that function and I could think that a javascript enabled spider can now read the real link under ads and follow them as it would be a normal text link...would it help ranking on SERP?
