Failed Niche site - experiment time

I've a site that I've been running for 6 months that I can't really get to perform, and for a number of reasons I've come to the conclusion that it's a badly chosen niche, and that I'm going to sacrifice it.

I've reached no 6 on Bing/Yahoo but am nowhere on Google and I don't think the return would be worth it even if I got that high - I'm getting about 5 visits a day from those 2 combined, so I think it is a bum niche.

However in the interests of improving my knowledge I'm going to close it out with a bang, so I'm considering a few options:

1. aggressive forum post building based on heavily varied LSI keywords (aiming for something like 1k posts with 1k varied keywords)
2. low grade spinning based on generic niche relevant texts, set to post on a regular basis
3. blasting hundreds of social signals out again based on variation of keywords

I'm pretty sure none of these are advisable techniques in this day and age but would be interested in feedback or any other bold suggestions. I've got access to Scrapebox but no other paid tools. I don't intend to spend any money (apart from maybe a couple of fiver gigs if it would do something)

The website monetizes off an affiliate scheme from a major online retailer, but isnt linked to adsense. It is on an analytics account of mine. I'll reconsider my strategy if I'm anything else I do is likely to get burnt by association.

BUMP. No thoughts on migrating a site to churn & burn?

Bueller?.... Bueller?

I think you should do high PR d0f0ll0w blog comments with varied anchor texts...

Disregarding relevancy?

My my approach to that would be a broad scrapebox footprint search then filtered down by PR and Df/nf. Sound about right?

Yes you could do that but If you want relevancy too then you should create about 10 different high pr web 2.0s on sites like wordpress and weebly etc. Include a 500 word article relevant to your site and include contextual backlinks in each article. Then blast the web 2.0s with maybe a a cheap service and that way you will still keep your site safe. I'll Pm you the service that I use to blast my web 2.0 sites, its only $15
