Google evolves by leaps and bounds, and now it is using natural keyword distribution formula to determine what websites have natural link profile and what sites don't.
Only if your link building campaign looks natural, then your link building campaign is effective and drives you loads of traffic.
When links are built naturally, then various anchor texts are used:
- URLs (http://disney.com/, www.bbc.com/ )
- brand names, (Walt Disney, BBC)
- keywords (watch cartoons, channel for kids; latest news, news channel)
- combination of keyword and brand name (Walt Disney park in France, watch Disney cartoons; BBC news, latest news on BBC channel)
- combination of keyword and URL (cartoons for kids at http://disney.com/, disney.com - official page of Disney; latest news on www.bbc.com, Neuron growth 'cuts memory space' by www.bbc.com/ )
- other words (learn more, find out now, visit the website)
