I am ready to begin article writing for my site but do not know exactly how many with anchored links to enter my landing page in each article. Should I only put an anchored text link at the bottom of the article or put them throughout whenever the keyword phrases come up? The difference would be either two links at the bottom of the article or about 7 throughout the contents. Will the PR be penalized for articles flooded with links to the landing page? Thanks in advance y'all!
