For those of you out there who purchase text links for SEO ... Which works better for you? Sitewides or homepage / section specific links?
For me, I've always had much better experience with sitewide links on relevant sites that generate a lot of traffic and have lots of pages indexed (a couple hundred thousand, minimum). In my niche, this isn't too hard to find, since most webmaster-related sites are fairly familiar with basic SEO techniques.
What's actually worked best for me is to buy (or get your link on, in some type of hat seo) just two or three really powerful sitewides. It's been my experience that's all I've ever needed to get well crawled and well indexed by Google.
