we have a site whose index page, thetapeworks.com , has appeared on google page 2 or page 3 search results for the search term "gaffers tape" for the last month, but is gone today, although there have been no changes to the page in about six weeks.
this has happened at least three times in the last six months, with the site periodically being missing in action for a week or two and then mysteriously reappearing without us making any changes while it is mia.
we hesitate to make changes while it is appearing in search results, but don't want to make changes while it is missing either, since it has reappeared on its own on more than one occasion
during this time it has consistently appeared on page 1 in bing/yahoo search for the same search term
anybody have a suggestion on where we should start?
