Should I 301 Redirect a Site with an 'Unnatural Link' Warning?

[AdeLewis]

Hey Fellow Mozzers,

I have recently been approached by a new client that has been issued with an 'Unnatural Link' warning and lost almost all of their rankings.

Open Site Explorer shows a ton of spammy links all using main keyword anchor text and there are way too many of them to even consider manually getting them removed.

There are two glimmers of hope for the client; The first is that the spammy links are dropping off at a rate of about 25 per week; The second is that they own both the .com and the .co.uk domain for their business.

I would really appreciate some advice on the best way to handle this, should I :-

1. Wait it out for some of the spammy links to drop off whilst at the same time pushing social media and build some good clean links using the URL and brand as anchor text? Then submit a recosideration request?

2. Switch the website over from the .com domain to the .co.uk domain and carry out a 301 redirect?

3. Switch the website over from the .com to the .co.uk without doing a redirect and start again for the client with a clean slate? I would still register an address change via Webmaster Tools.

4. Add a duplicate site on the .co.uk domain. Leave the .com site in place but rel="canonical" the entire domain over to the .co.uk

Any advice would be very much apprecited.

Thanks
Ade.
