To improve a Web page's position in a SERP, you have to know how search engines work. Search engines categorize Web pages based on keywords -- important terms that are relevant to the content of the page. In our example, the term "skydiving" should be a keyword, but a term like "bungee jumping" wouldn't be relevant.
Most search engines use computer programs called spiders or crawlers to search the Web and analyze individual pages. These programs read Web pages and index them according to the terms that show up often and in important sections of the page. There's no way for a search engine spider to know your page is about skydiving unless you use the right keywords in the right places.
Here are some general tips about keyword placement:
One place you should definitely include keywords is in the title of your Web page. You might want to choose something like "Skydiving 101" or "The Art of Skydiving."
Another good place to use keywords is in headers. If your page has several sections, consider using header tags and include important keywords in them. In our example, headers might include "Skydiving Equipment" or "Skydiving Classes."
Most SEO experts recommend that you use important keywords throughout the Web page, particularly at the top, but it's possible to overuse keywords. Your skydiving site would obviously use the word "skydiving" as a keyword, but it might also include other keywords like "base jumping" or "parachute." If you use a keyword too many times, some search engine spiders will flag your page as spam. That's because of a black hat technique called keyword stuffing, but more on that later.Thank you...
