It looks to me (at first glance) that there are an awful lot of outbound affiliate links from your index page. I think that “could” trigger a flag in Yahoo’s algorithm that your site is an “affiliate link farm”. (I think the item on the list that this would fall under is Massive domain interlinking- Use of affiliate programs without the addition of substantial unique content
I count about 96 affiliate links to casino on the righthand navbar. Then you have 7 banner ads for casinos in addition to that.
Then it looks like you have about 500 or so words of content on that page.
I think that could cause an algorithm to say, “Hmm. That’s an unusual number of affiliate links compared to the amount of content no the page.”
What you might consider doing is linking each of those casino names to a casino review page for each casino. Or simply reduce the number of casinos that you’re advertising on that page. The other thing you could do is rewrite or write more content on the page, so that you have a higher ratio of content to affiliate links.
A human editor reading your content probably wouldn’t find it “substantial” or “unique”. So if you’re going to actually use the form to resubmit, you should consider the content pretty carefully.
You also need a lot more backlinks to your site.
