Math Class
This is not your grandpappy's math class. In SEO, there are quite a few mathematical considerations. Let's discuss just a few.
ANCHOR TEXT RATIOS
The term anchor text ratio refers to how often a particular string of anchor text appears within the total pool of all your backlinks. Many newbies make the mistake of flooding their website with a bunch of links using the particular anchor text they want to rank for, which in fact this will most likely end up actually getting you penalized for an unnatural link profile. It's just not normal that if you had a million backlinks, that 80% of them would all be exactly the same. Statistically, most backlinks are actually random bits of text like "click here" or "visit now" that have nothing to do with any particular subject, so your complete anchor text profile should reflect that. Brand links, which contain your company name, are probably the second most common, and it's OK to have a number of them as long as you are not using an Exact Match Domain (EMD). Finally, there are raw URL's such as http://google.com. As long as you are not an EMD, it's OK to have a some of these.
KEYWORD DENSITY
Keyword density is about how much of the language on your website page consists of keywords. Depending on who you ask, most experts will tell you that this should be somewhere between 2.5 - 3.5%. The old practice of keyword stuffing will now only get you into trouble.
LINK VELOCITY
Link velocity refers to the speed at which new links to your pages are being created. A pattern of increasing link velocity can possibly indicate to search engines that your site is becoming increasingly popular, but that same attention can also work against you if, when a closer is taken by Google, your linking is unnatural.
