A link wheel is a system of websites that point to each other in an attempt to improve rankings in Google’s organic search. The promoted site resides at the center of the link wheel. All other sites (spokes) link back to the promoted site.
When you link multiple authority sites to each other and they are all linking out to your site, guess what... the search engines become happy and they you share a little of that authority!
To make the most of Google linkwheel, you must:
- Create unique and valuable content that begs to be linked to.
- Monitor which content on your blog or site has performed well.
- Search Google for the best wheel spokes to get links from.
- Email the controllers of the spokes and inform them your content exists and ask for a link.
P.S - There are, however, mixed opinions over the legitimacy of this technique in the eyes of search engines.
