I have a plugin which posts to Facebook when I update or create a new post. My page “Important Resources” has links from sites that might not be specific to gas mileage. I do create new posts, maybe 2 or 3 per month.
If I get my site to post to Twitter, make a press release, and remove the non-relevant links from the “Important Resources” page, that might help? I got links from directories when I first built the site in 2005, and have kept the ones that are not dead sites.
What I cannot understand is that it still appears on page 1 of a Google search for ‘gas mileage enhancers’ and ‘best gas mileage enhancers’, but not at all for ‘gas mileage’ or ‘best gas mileage’. I know two of those keyphrases are not popular, but my point is that the site does well for the other two.
