I base my research on the exacts and phrase matches - the broad match is unrealistic for competitive terms IMO.
This might be obvious, but do your page title and description accurately reflect what people using that term are looking for?
i.e. it's no good ranking #1 for "widget testing" if your title/description says "buy widgets now".
I read somewhere that quite a large percentage of searches result in no click at all.
If you run a search and the results aren't what you need, people often just search again with different terms.
Does anyone know if Google's keyword stats are for unique searches? Because if every search is counted, and you get a few webmasters running automated searches regularly, those results are going to be heavily skewed for the more competitive terms.
It would be nice to think that Google strips out automated searches, but I think if they could do that they would be preventing them already - and someone would come up with a way round it, because there are a million webmasters who want to check their rankings easily.
I hope I'm wrong on this, I much prefer the seasonal variation explanation, but I think it could be a factor.
I have a few reasonable #1 positions that I was expecting more traffic from, but I am finding they get traffic in fits and starts. That fits in with the nature of sports betting as obviously there is more interest around big events.
Then again, I also have a one page site that is #1 for a single exact match term.
It gets more visits for that exact term in a month than the total exact match searches listed on the keyword tool.
Webmaster Tools gives it a 40% CTR, so clearly those stats are a little out - I can't believe the term has doubled in popularity in 12 months.
Interested in quality, relevant link exchanges and deals, especially with UK sites.
