For contrast, I have two other sites which are blogs. They both have an average SERP ranking of about 30-40 (but are targeting some very high volume terms) and yet, they receive a CTR of about 4% and 6% respectively. (The site with a 6% CTR is ranking #1-2 for a particular search term which is bringing in maybe 1/3 of its total traffic.)
Do the numbers look right for my E-commerce / Review site? At this point, I'm thinking about split testing the Meta Titles and Descriptions to hopefully boost my CTR but I'm wondering if this is a lost cause if I'm competing against Amazon and other big boys?
