To help me test landing pages, I put the URL to the page into the Site-related Keywords part of the Google Keyword Tool. What I have noticed is that it give inconsistent results. For example, I can put the URL in and get one set of results, then without changing anything I click Get More Keywords and get another set of results. And sometime the results don't even show the keyword, or keyword phrase on the page, even though the word/phrase is strategically used and repeated a number of times. Does anyone understand how this tool works? And do you think it is useful?
