Welcome to the Q&A Forum

Hi Alan - I agree, That is what I said we do not post on such sites where post frequncy is fast. Though our content is very good and talks authority & not sound like commercial pitch...

Would you mind sharing a link the page? It would be much easier to talk specifics if we could look at the page. In general terms, you want to examine the page and your site for the desired keyword. The two questions I would ask are: Is your page optimized for the "x1" keyword or phrase? Earlier today someone asked what he could do to improve his ranking for "Las Vegas vet". An examination of the site's home page showed that phrase was not used a single time on the page. You need to ensure you offer solid content with appropriate usage of the term, without stuffing the page. Is your site canibalizing your SERP? When you search for the keyword, do other pages from your site appear? If so, try to figure out why. Google apparently believes the page offered is a better match for "x1". You can help by modifying the page a bit and replacing "x1" with a different keyword designed for that particular page. You can also use anchor links for x1 throughout your site. These links would help users find the desired page and let Google know you are focusing that keyword to a particular page.
