Agree with what Keri says. Also, when looking at your link exchange it says Funny Jokes, snowboards, medical transcription, Loans.net, etc.
From Google's Quality Guidelines:
Avoid the following techniques:
Participating in link schemes
Loading pages with irrelevant keywords
From Google's SEO Guidelines:
Avoid SEOs that talk about the power of "free-for-all" links, link popularity schemes, or submitting your site to thousands of search engines. These are typically useless exercises that don't affect your ranking in the results of the major search engines -- at least, not in a way you would likely consider to be positive.
Also, looking at your rating stars on Google in rich snippets. RS spam and fraud will be the next thing they crack down on. I'm not saying you didn't get 5 stars but you have a lot of pages that no longer exist with 5 star ratings... some of which never allowed on-page rating. This "looks" like RS spam.
Looking only at the site:
-
Why is your sitemap in the navbar? Does it help visitors get anywhere except to your link exchange, which is hidden on the navbar?
-
Quotation should say Quote. We don't give quotations.
-
The quote about Google makes no sense to me. Maybe I just don't "get" it.
-
You swiped the SEO process graphic directly from a recent Moz post (although Moz didn't create it either. It seems to have come from http://www.webcopywriter.it/seo/ - they have the oldest record of it on Google Images.)
-
You aren't an English speaker natively. I'm not sure selling services in English will work well for you. "We believe that the web and first page rankings are for all." "Art is priceless, alike the SEO" You really need a native English speaker to fix most of the site pages if you're going to continue this direction.
I hope this review is not too harsh and is what you are looking for, if not what you wanted to hear. This site has a LONG way to go before I'd make it public.
