I have a three year old site, bit of a hobby site. I finally managed to place the adsense in just the right places and was getting a decent CRT and was making around £10 a day (it was only making £1 - £3 for most of its life). I know this is probably shit for a lot of you guys but for the niche and for the traffic its not too bad. Anyway, back on the 20th of January the sites theme updated and crashed the site! Lost all the tweaks etc that I had made and the sites was basically a mess. Its now been fixed. I had the same guy that made the tweaks do them again to the site (with a child theme this time!! and backup). The site looks exactly like it used too. The traffic is all back and the adsense ads are all in the same location. But the CTR/RPM has gone to total shit! Its been 2 - 3 days since the tweaks but it barely makes £1.50 a day! Its really strange as all the ads are in exact the same place. Anyone got any ideas?
