I found a very interesting thread at HighRankings named The Q-factor where a new member said "I recently got a reply from a search engine, after having submitted my page. Amongst other info it stated a Q of 5 for my site."
Now what the heck is a "Q factor"? No one in the forum seems to know. I do not know. Some guesses were made, such as "More than likely the SE that reported a Q Factor was refering to their *quality rating* and terming it the *Q Factor*."
But this makes no sense to most. Does the search engine optimization industry have a new phrase? "Q Factor" sounds like something cool to tell a client.
