A question of rankings (with actual domains)

[NetvantageMarketing]

Working with the main site featured in this Open Site Explorer comparison (you'll need a pro account to view this), and have been for quite some time. Recently we've slid behind Ebay (huge brand, I get it), but the other competitors don't really make sense to me. Main phrase is pontoon boats, and maybe I'm too close to this, but we seem to be in the best shape overall in terms of the domain, the page itself, and even our social media is pretty successful (we're closing in on 5,000 likes and have a pretty engaged audience). More internal linking is an opportunity, but I'd like another set of eyes (or several for that matter) to weigh in on opinions. I'm a bit stumped. Thanks Mozzers!

Could this perhaps be an issue with your ranking reporting instead? I see your site as #2 (behind Wikipedia) on Google.com search.

That's an interesting question. We use two different rank tracking softwares, we have offices in two different cities, we all know how to de-personalize results, and we look at Webmaster Tools' ranking data as well and we're between 2-5 depending on what you look at. I can say our traffic is down a bit for that keyword, and Webmaster Tools is showing us ranking more at 3-4 than at 2 anymore. So something would seem to be up, or this might just be the new norm?
