Google Webmaster notice of detected unnatural links to my site ??

I received a message from Google month ago about "Unnatural inbound links" to my site !!

In fact i used some gig from Fiverr i think they build bad links to my site.

My main niche is drop from 1# page to 22# page, and my visitor is down by 30% but ANOTHER keywords is still 1# position in first page of google !! just main niche.

I have report for that gigs i used from Fiverr , is best if i send that report to google in reconsideration request. ??
May my main niche is back to 1# page ?

or what should i do ??

Thank you

This happened to me and I'm removing most of the links which are count in webmaster tools. Then will send the reconsideration request.

In my experience, contacting Google with a recon request is generally a VERY bad idea. You're just asking them to look further into your site. If you look at it from their (ruthless) perspective, ANY link-building that you've done is manipulation. So unless all your links are from completely unique content and have obviously been achieved naturally and through their own 'merit', they'll call it SEO/manipulation.

It's better to ignore it, and keep on building links, ensuring you're adding the correct diversity and variety to all link-building methods and anchor-profiles etc. Make sure that you're also not falling foul of an algorithmic penalty as well - i.e. Penguin anchor-optimisation for instance.

Sending Google a list of link-building evidence that you're bought on Fiverr is the worst thing you can do. It openly demonstrates that you're actively looking for cheap/quick ways of link-building.

First try to remove the spammy links. Going to them for reconsideration without doing any corrective action is pointless.
