If Xenu were to crawl every page of Got2Bet, then yes. If you are running Xenu from your site, it checks your links and subsequently comes to Got2bet and hits the page it’s supposed to, then no.
You would have no reason to ask Xenu to check every page on Got2Bet for a single link – unless you were looking for a linkback, in which case Xenu should be checking a single page.
Large amount of time is not necessarily a problem – there will be people that go to your site, see a few articles that interest them, and spend perhaps hours reading all the other articles.
This, in fact, is what you want to encourage, by all means.
The issue I am talking about is when a spider, or something which purports to be a spider, comes, doesn’t properly identify itself, and proceeds to hit hundreds of pages in a few seconds. That is either a spider, or a site grabber.
You may be getting more traffic – but is that traffic human? Google spiders images, maybe more people are looking to steal graphics?
Graphics are the #1 reason for slow page loads, and will always increase the size of the page more than text ever will. Plus Google will never know the content which should have been represented as text – and in most cases this will not help your SERPs.
