For all webmasters and SEO specialist there is new trend. We had used as many exact match words as possible in anchor texts but this could hurts the web site now. Partial match means any anchor text that contains at least one of our keyword phrases.
It seems that people rank higher when there are partial match. For example if your keyword phrase is ‘cleaning services’ it is better to use ‘We provide the best cleaning services at our area’ instead of ‘cleaning services’. When you have partial match there are a lot more phrases and long term value that is more likely to give you better looking link profile.
As Google is improving its algorithms and it is getting more intelligent we need to follow the new standards and make web sites for humans not for search engines.
