143489 seo optimisation

I have the site [login to view URL] its doing ok for some terms on [login to view URL] but not necessarily the main terms i wish to appear high up for. Algarve property portal on [login to view URL] is doing fine. however - algarve property algarve estate agent algarve real estate are all struggling. Im looking for a sensible solution to increase backlinking and generally seo optimise the site for better results on [login to view URL]
