They will tell you the most popular phrases related to your theme/topic and are a good guide as to what keywords to use in your copy/links/title/description etc.
From the number of searches per month/day each resource gives you per keyword, you can probably guesstimate a CTR depending on the set of keywords.
But as stated by HawkGirl it largely depends on your keywords, title, description, product, and indeed the wind direction.....
Don't forget, a really good title and description will be what attracts a users attention and not necessarily your position.
Although me saying that, you can call me a hypocrite cause one of the engines don't actually list any listings under a certain bid amount so if you are bidding under that bid amount limit, you may not even be visible in that engine at all.
In some sectors for some keywords if you get 0.5% you are doing well and will get good ROI, a sexier title and call to action may get that up to 0.7 or 0.8 which should corellate to a bigger ROI all things being equal.
I'd say if you were in a niche market then 5-10% is probably very low for a top 3 position, but it depends on the ads you have and the competitors you are up against. If there are no competitors and you are not getting a good CTR then your copy probably doesn't hit the message home.
Good luck!
According to OV the only number that is correct is the "Suggestion Tool" numbers. They have a filter that, that removes "script" searches.
I am also trying to do a specific marketing for a few KW's but, the only way that I can tell how many searches were done for a specific KW, it to wait until the "Suggestion Tool" data is made available every month. I would have to do the math manually.
This is info from OV themselves. They claim to be working on this, but I think it's will take too much on their part, so they may not be doing anything.
Look at your monthly data, you'll see the difference in the "Suggestion Tool" data, vs. the monthly data's report.
So in short, you could be doing better than you think. It's been my experience that position 1-3 get most of the cliks. 1 and 2 are about even.
Hope this helps.
