Just keep a heads up on you budgets and CTRs over the next week or so. Google Adwords is rolling out the reported changes from changing the paid ads on the search results to a yellow background. They have been testing this for a while and more and more people are coming to me with notices that they are constantly seeing yellow backgrounds on SERPs.
This is significant for advertisers and account managers because I expect to see an significant increase in clicks as the change from blue to yellow will temporarily suspend the average users “ad-blindness”, ie the mental blocking of ads on SERPs. Budgets can get eaten up quicker than expected but should eventually level back out but everyone should be aware of this upcoming change.
