I've spent the morning going over our WebTrends reports for last week on a couple of our sites. Neither of these particular sites has paid advertising.
Both have received visitors from sitefinder. When I looked at the terms these people were actually searching for it was a combination of nothing to do with our particular site and mispellings of our site.
One site is a generic term, www.generic.com. In two cases the searchers were actually looking for other companies that have the generic term in their url's. Our site was presented as an alternative and they visited it although we don't provide the service they were looking for as determined by their original url.
In the other cases it was a mispelling of our name and they were presented with the right site and clicked through.
How do I feel about this now? If it were just this I would be fine with it. Where I feel uncomfortable is that as a PPC advertiser do I want someone clicking on my ad if it is presented when someone can't get their url right. Is this valid profitable search traffic? If given a choice I would opt out.
