Follow this Penguin and Panda Safe Anchor Text Formula

15% of your anchor text/backlinks should be focused on your primary keywords.

35% of the anchor text should be Brand based – this means any combination of your sites wording (http://alexwhalley.com. www.alexwhalley.com. Alex Whalley, AlexWhalley’s website, etc etc)

40% need to be user defined (meaning anything that a normal layman would use to link back to your site: Click here, view more, check this site out, follow this link, go here etc etc)

10% need to be longtail keywords, basically anything that includes your primary keywords but worded differently
As you can see, this new anchor text algorithm will make your backlinking look natural to Google and will help you rank for the primary keywords in question (this is how the Penguin has impacted linkbuilding and as you can see from this new pattern, and applying some common sense – the sites that rank with this in mind are the ones that naturally get linked to and are not spamming the web with keywords)

It is also important to remember part 2 of the algorithm…

The new algorithm also requires that the links are not all pointing to the home page, meaning that in the case of squeeze pages … a blog is required. (at the very least a few pages of SEO optimised content on the backend)
25% of your backlinks point to the main page or homepage

75% of your backlinks point to deep nested pages on the site (any other page)

I also recommend making a conscious effort to link OUT to relevant and authoritative websites every so often as this shows Google that you are providing quality references for your readers and not just hogging all the love for yourself
