Ongoing Maintenance
Keeping up with the Search Engines
Your web site position will change from time to time, and these are the two main reasons.
(a) The search engines change their algorithms (their criteria for balancing keywords against web page content) from time to time, so your ranking can go down (or sometimes up!).
(b) Other web sites are added, or existing web sites change their content.
To keep on top of developments, you need regular, ongoing maintenance.
For best performance, your web site needs monitoring and rebalancing once
a month; otherwise, I recommend no less than once every two months.
