So Google makes a slight change to title on the Adwords Ads from “Sponsored Links” to “Ads” and raise click through rates by 11.4% to be exact according tests done by The Search Agents.
This is very odd since most people would agree that the change would be insignificant if at all. Instead their tests show a double digit jump. One of the most accepted theories is that simply because it was a change it possibly could have become more obvious to regular visitors.
Anyone that currently does any good amount of advertising on Google Adwords should check out the Search Agents blog for more details on their findings that could impact your ad spend.
