If your core business is not website development and SEO, you probably need an SEO maintenance contract with an experienced professional. We do this by performing ongoing tests, applying new techniques and much more on a monthly basis. Real estate agents are experts at real estate issues; web developers and SEO professionals are expert in search engine optimization issues. Please PM me as to what you can do and for what price (monthly). If hired I will try you out for one month and if it works out I will continue to use your services on a monthly basis. I prefer those with experience (obviously) and it is important you can provide me with examples of your work and results. Again I already rank high and just want to maintain and build on that.
