Hello-..sorry to bother you again, but everyone here seems to know the answers! (And it's all interesting)

If certain search words always bring up a certain site on the top of page 1 with an underscore made of plus marks "++++++++++++++++" under it.....what does that mean?

I thought paid ads came up highlighted, not underscored.

And this particular site is really not very relevant to the search term.

Thanks!

I've never seen this before. Can you give us an example? What are you searching for and with which search engine?

(Is that kind of link legal here?)
Does the DOT.GOV have anything to do with it???

Oooh ... look at the cached version of the guy's site. He actually has +++ signs in his body copy.
