So if I submit 25 posts to rank or move up the SERPs for that keyword what percentage should I use "dog training collars" as the anchor text in those 25 posts? And if I need to vary it do I still use the base keyword and just add an extra word at the front or end of the keyword I want to rank...i.e. best dog training collars, dog training collars guide, etc?
Or just use a new variation all together for like 20% of the anchor text like "dog collars", "pet training collar", etc.?
