Since we are constructing a sizable number of links for the Foundations, it is important that we maintain a relatively low anchor text to link ratio.
So that Google thinks our progress is natural, we use words like “click here,” “learn more,” and the like in the URL, domain name, and neutral anchor text (e.g., “click here”). We plan to include those more specific keywords (about two to three per Foundations order) in both the Foundations and Guest Posts.
