Hi I just want to work out some sort of business plan, can few people who have 1st position on SERPS tell me what is usually their CTR as a percentage of impressions. Lets say that key-phrase is "blue widget", that according to Big G's KWT that phrase gets 100,000 impressions and you have a bluewidget.com domain. What would be CTR as a percentage of those 100,000 impressions. Just few examples, so we can get some ideas.
It varies from Web page to Web page (note I said PAGE and not site). It's not something that can be mathematically tracked or anything since it depends on human psychology. How well are the title tags? Is the search engine using the META description tag? Or is it using text from within the page, or a DMOZ/YDIR listing instead? If it's using the META description tag, how well is it written? Does it contain a clear call to action that compels the searcher to click that link to your Web page?
