Some people never even get past the basics of understanding the importance of choosing the right keywords. I realize that some aspects of SEO can get quite technical and mathematical, but it’s not necessary that you understand everything, but it is necessary that you do something. That means just do it and perhaps the things you don’t understand now will become clearer later.
The right keyword or phrase to some people is the one they think someone would use in a search query, but that’s usually not the same as the one most people actually use. Let’s say I have a new product and I have given it the name "Swopper Pages." I design a web page for my swopper pages and set about becoming No.1 in Google for the keyword phrase "swopper pages." How difficult do you think that would be ? Let’s say when someone types swopper pages into Google to do a search my webpage comes up as No 1. How many people use a major search engine like Google every day or month to do a search using the term swopper pages ? It’s relatively easy to be No.1 in a major search engine for keywords that no one uses to search for because they have very little competition from other web pages. If no one uses your chosen keyword phrase in a search query on a search engine it does not matter if you are No 1 for that term, you will get virtually no traffic from that keyword phrase. If you fail to understand about choosing the right keywords, then almost everything else you could do with regard to SEO for your website will be a complete waste of time.
So let's start with the most important aspect of SEO and that’s choosing the right keywords. But first what are keywords ? Keywords are the KEY to your success or not, with the search engines, because for the most part, search engines only understand words, the words and text that appear on a web page. Keywords or more precisely a keyword phrase (2 or more keywords in a phrase) are used in particular ways on a web page so that they tell the search engine what your web page is about. Let’s say your webpage is about fishing and you choose keywords to put on your web page that you think are sure to tell the search engine your page is about fishing. After all its plain to you that your web page is about fishing. But what you don’t realize is that the search engine has its own way of reading a web page and it decides your page is not about fishing but about boats. Not only that but the search engine already has 1 million other web pages about boats, so exactly what priority is it going to give your web page in its catalogue ? So not only have you not designed you web page so that the search engine clearly understands your page is about fishing, but you have also ended up competing against web pages for boating. Your "boating" page has far too much competition with over 1 million other pages, is lost in a crowd and will never be found when someone searches for the term fishing.
