Hi, I currently run several Adwords campaigns and have many Quality scores judged as great. In fact the lowest score I have seen is a 7. Despite this my cost/conversion has rocketed over the last 2 months and is now almost twice as much as I used to pay. I use negative keywords, common group phrases and bid higher on converting keywords yet still have little success in bringing down my costs. Does anyone have any ideas on what I can do up my conversions?
Try playing with your ad texts. Look at those that have the best conversion rates and then work on refining those to see if you can improve upon them. You can also look at your landing page to see if anything there can be tweaked to encourage better conversion.
