Do I have any harmful links? If so, what should I do?

URL in question: www.nasserilegal.com/criminal.html

I'm using OSE and see some questionable backlinks. At first glance, if you look at the page authority and domain authority, they look great. Once you go to the actual pages, they look spammy.

If the links are hurting the rankings for the site, should I try to remove the links manually or just ignore and continue to build good quality links or even build a new site?

I noticed for the last couple of weeks, the rankings started to slip.

Thanks in Advance,

Lucas

Have Google sent you a message indicating that they thik they are spammy?  If not then they may not be as bad as your assuming.

Looking at your link profile sorted by anchor text, I can see a few things.  First of all, your url is your most popular link and that is good.  In looking at your next links they are primarily anchor text. There's nothing wrong with that...in fact that's a good thing.

But I'm concerned when I look at the quality of those links.  They are obviously made by an SEO and not natural.

With what we currently believe about Penguin, the fact that the majority of your links are using your url as an anchor is likely enough to keep you from being affected by Penguin.  BUT, I would venture a guess that if a competitor decided to file a spam report on you, you could be faced with an unnatural links penalty.  I can't say for sure though as I only looked at a few of your links.

At this point, if your ranking is not suffering, I'd probably do nothing about these links.  But I certainly wouldn't have your SEO company build any more!

EDIT...I just saw that you said your rankings are slipping.  You'd need to dig deeper into your analytics to see if Penguin actually is an issue here or whether there is something else going on.  Here is a resource that may help you figure that out:  MyTrafficDropped.com/Penguin
