I've noticed recently that a lot of competitors for a client of mine have spammed their way to the top of Google. Their SEO technique includes:
Having numerous keyword-stuffed links at the top of the page which all link to the home page.
Having a huge scroll down section under the website which is full of poorly written, keyword-stuffed content that just keeps saying the same thing over and over again.
Obtaining numerous backlinks from irrelevant sites that they have obviously bought or exchanged.
I thought Google solved this issue ages ago? It's not just one site, it seems to be all sites on the first page (I gave up checking after that). How can these cheaters be doing so well?
