For those of you who aren't familiar with these two SEO techniques; a link wheel is basically creating 10 or more new web 2.0 sites/blogs on a particular topic related to your targeted website. On each of those sites, you post your unique content, and include 1 link to your targeted site, and 1 link to one of your other web 2.0 site/blog. On the other hand, a link pyramid requires you to have a few web2.0 sites/blogs/microsites linking to your targeted site with other sites linking to those sites and maybe more sites linking to those sites (yes, exactly what a pyramid is). So this question is for those of you who have experience with building link wheels and link pyramids: Which SEO strategy have worked best with your sites in terms of ranking in the search engines? Thanks!
Personally I have found building link pyramids the better strategy, providing they look natural, and not spammy. I generally build my pyramids over 20-30 days. Others may disagree but I have had a lot of success recently. Just remember quality not quantity.
A link wheel is a waste of time (it's simple for Google to detect). A pyramid, if done right, is much better. As lapseo mentioned, built over time (rather than instantly). It can be a lot of work, though, but if you're having problems kick-starting your site, this might help (assuming your site's content is good). You have to remember though: it's black hat and, as a result, your site might end up getting penalised and pandalised.
I prefer combining the both together. With the latest massive Google updates, they can spot a website using one of these tactics, therefore it's better to mix the both together, it'll be a Killing & Undetectable
I would say link wheel is the best SEO technique and very important fact is that keep the technique under limit, irrespective of what it is, so that you can understand the real effect of the technique. I have used link wheel to some extent and got good results due to it. I kinda did it differently.
Google seems hot on natural looking links at the moment. The closest I'd get to a tiered link is social bookmarking of a blog post.
