I think that there is a much better approach to taking up more of the search engine landscape than potentially using black hat techniques. Here is what I recommend.
- Invest in PPC
- Create a video on that product and submit to video sites such as Youtube.
- Submit that product to Google Product Search
- Create a blog post on that product that is useful to consumers
- Talk about that product on Google Plus.
What people find useful ultimately is the best remedy for strong search engine rankings.
