I manually submitted a site to google, and it has no server problems. However, the site drops in and out of google results. When in (and searched for my by its business name, and town) it comes top of the list for many slight variations on its details, but when it drops it, it really dissappears! Only, a reference to it in a “links” site i made (high ranking, well for a local site, when searching for local businesses) and thats it. Just a reference to it in another site.
How can sites drop out (which I can understand) but then appear prominently again?
It does this for about 2 or 3 weeks at a time.
