yes, your no longer considered a free customer for say your a paying customer. So as soon as you stop paying even if you had a free listing you lose your listing. For a time untill you are recrawled and indexed by the free side of the crawl.
It's odd finding this just now, because five minutes ago I got off the phone with Ask Jeeves. I asked them why, a month after doing SiteSubmit for a lot of pages, most of our pages just VANISHED from Jeeves and Teoma. Not all, but many (after being ranked in the top 5 or 10 most cases). It's a very legitimate site, a household name, by the way.
I have a couple of possible explanations (unlike the Ask Jeeves person who was nice but had no explanations):
1 - the site's Google AdWords listings, which started same time as we did SiteSubmit, caused the non-sponsored listings to be removed. 2 - SiteSubmitting a page causes any free listings for the page to be removed from the index, and there's a time gap between this happening and SiteSubmit picking up the listings, during which the pages can't be found.
Any ideas? We have a phone call review with the client tomorrow and this is doggone embarrassing after spending $$$$$ on SiteSubmit at our recommendation! The client is paying us to get them to the top for BOTH sponsored and unsponsored listings on SE's like Jeeves. If we stepped into an tradeoff I'd like to know about it!
