What is relevance in SEO?
 Relevance is a central concept in search engine marketing, but you will be hard pressed to find any reasonable definition for it. Most SEO experts take the term for granted, and the rest of us just nod along. It is not very complicated, but it does involve some very core ideas, so listen closely. In SEO, relevance is a criteria used by search engines to determine the importance of a target (page, keyword, website) within a niche. Since search engines are primarily concerned with serving user queries, the role of relevance comes up most often during searches. For example, if I search for the term search marketing on Google, the search engine will analyse its index and provide me a list of web pages ranked by how relevant they are to search marketing  in this case the top result is Overture, now known as Yahoo! Search Marketing. Note that search engines dont explicitly deal with niches or categories of websites. Instead, an SE treats the Internet as a loosely defined grouping of topical pages, with those topics forming sub-groups of their own.

 Search engines and relevance Search engines assume that websites in general will follow the mantra of information-targeting, with the ideal website in a niche being the one that is most relevant to that niche. Sounds simple, right? Here is where it gets interesting. Search engines measure relevance on different levels, or different categories if you may. Once you understand the above definition, they all make sense by themselves. For starters, there is content relevance  is this pages content relevant to a search query (and that querys projected niche)? This is where on-page optimization is so important. Search engines use keywords to measure relevance, but they arent checking for keyword density; in fact, they are checking for keyword placement in the page. A second criteria is link relevance  whether the sites linking to you are relevant  i.e. in the same niche (or closely related to the niche), and whether the sites YOU link to are relevant as well. This is, in a nutshell, off-page optimization or link-building. Relevance in search engine optimization has been the biggest stumbling block for webmasters  the concept is so important that every aspect of SEO is governed by it, but yet so obvious that many of us overlook it.

 How useful is keyword density
 Keyword density was once the single most important criteria for judging the value of a webpage. Im talking back in the pre-Google era (now if THAT doesnt give you a hint about how outdated keyword density is). However, with Googles PageRank algorithm and the general trend towards off-page factors determining more and more of your websites rankings  the importance of keyword density as an on-page optimization tool diminished. People continued to theorize about what the ideal keyword density should be, and estimates ranged from 2% to 8%. Keyword density, in case you are wondering, is measured by the following formula:
 d = x / y where:
 x = No. of times a keyword is used in a block of content (page)
 y = total word count of the page
 d = keyword density

 The problem with keyword density is quite simple  it is very, very easy to manipulate and spam. Spammers used automated content generators to create highly optimized web pages with high keyword densities. As search engines started to set limits on acceptable keyword density, spammers got smarter and smarter and reduced their keyword density as well, making it especially hard for search engines to separate spam content from genuine, useful content. Since search engines could not conceivably check every page manually (As a rough estimate, Google indexes 8.1 billion pages  and pages are added daily), and they couldnt tolerate spam in their search results, search engines devalued keyword density as a ranking tool. In fact, I wouldnt be surprised if keyword density did NOT affect your rankings  in fact, keyword positioning (placing the keywords in title tags and header tags) as well as thematic keyword relevance (a fancy term that refers to how related your core keywords are to your websites main theme or niche) is far more important in terms of on-page optimization. And that, of course, pales in comparison to how important off-page optimization, or link building, is. So, if possible, ignore the bounds of keyword density and focus on the following:
 * Good, useful, quality content
 * Keyword positioning
 * Keyword relevance
 And once youre done with the basics, move on to the next page (or start building links).

 Do web pages need a minimum number of words to rank well?
 Theres a myth going around in some search engine forums that you should have a minimum word count for web pages to satisfy search engine requirements. Lets put that myth to rest  theres no minimum requirement for web pages to rank well  in fact, there are many, many web pages that rank at the top position for highly competitive terms WITHOUT having too many words on them  for example, a search for the term resume samples on Google gives a top result of a page that has ONLY links on it  no serious content. This is a highly competitive term with over 150,000 searches each month according to Yahoo Search Marketing  a figure that translates to almost a million searches each month on Google. In other words, word count is not the defining criteria for high rankings  you could have 250 words, or 500, or 1000, or even just a 100 words, but that is still a small part of your on-page optimization, which in itself plays a small part in determining your websites rankings. In practice, you will always have different types of pages  some will be main pages for the website or link pages (both usually lacking too much content), while others will be article or informative pages with loads of content. The key is to work on the right page structure for each type of page, and not the word count.

 How often should I change the anchor text in my backlinks? The short answer to that is: pretty often. The long answer?
 Well, it starts with a definition. Whenever we talk about link-building, it seems necessary to mention organic SEO  where other websites link to your website by themselves (as opposed to an artificial link exchange) because they genuinely find it useful. Why is this important? Because once you understand what search engines are looking for in links, youll know how to dominate the rankings. Relevant to the question, search engines try to measure the originality of the link  that is, the chances that this link was natural or artificial. Since most of the links (and almost all of the ones that you will get in the beginning) pointing to your website are artificial, you have to make them look organic to avoid any penalties from the search engines. For example, suppose that you are setting up a website on copywriting  assuming that you have the on-page optimization done and dusted, lets talk about how you can regularly change your anchor text.

 Your Anchor Link Strategy
 First, we take your core list of keywords:
 * Copywriting techniques
 * Learn copywriting
 * Copywriting seo
 * Copywriting tips
 * Copywriting course
 * Copywriting services

 And so on. Now, take each keyword, work it in an attractive headline and write 1-2 lines describing your website  no hype, no keyword spamming  make it attractive and useful to the reader. Make sure that each description is different  it cannot be totally different, but it should change a bit. If you do that for each keyword, you have 10 or more sets of link details  the headline makes the anchor text and the 2 lines will act as a description. Once you have this set, start from the first combination and switch to the next one after 25-30 links. This way you can cycle through your list and maybe get to 300 to 400 backlinks before you get through your set of anchor text and description combinations. If you have fewer core keywords (a tiny niche), you can space out the changes  say every 50 links or so. What to do when the list is up? Alter the anchor text and descriptions for each keyword and do that for the whole list, then start all over.

 If you follow this formula not only will you be able to regularly alter your anchor text (and thus make the link-building process look natural), but by targeting so many keywords within the list you can also end up ranking highly for all of them.
