When I first started out in search, it was predominantly working on pay per click campaigns before I gradually started working more and more in SEO before eventually focusing nearly all my time in this area. Hence, the name of this blog and why some of you who may remember my posts from 4+ years ago they were mainly about pay per click, now they focus a lot more on SEO (I still do PPC today though). I think that grounding in PPC has been a huge benefit in terms of perspective for SEO and its development over the years. - PPC Blog
Ever since Google launched the Search Query Report in AdWords, advertisers have been using the data to refine and evaluate their current keyword lists, identifying any potential new keywords that they could add into their accounts. As those of us who use these reports know all too well, when looking at these reports you do see the dreaded "... Other Unique Queries" quite a bit - This is obviously not a real search query ;-) - PPC Blog
Over the past couple of weeks Google have been testing new background colours for their Adwords ads again. Google changed from their usual blue background to a yellow back in 2007 which is what we see predominantly today in the SERPs. Now it looks like testing time again, I am connecting to a DC with a pink/purple shade background - And also a much much brighter quite striking shade of blue - Are you seeing any other colours? - PPC Blog
