them is necessary for you to develop your search engine promotion
strategy. The following summarizes the nuts and bolts of search
engine ranking, hope this can serve as a door for you:
Pages with keywords appearing in the title are assumed to be
more relevant than others to the topic. Search engines will also
check to see if the keywords appear near the top of a web page,
such as in the headline or in the first few paragraphs of text.
They assume that any page relevant to the topic will mention those
words right from the beginning.
A search engine will analyze how often keywords appear in relation
to other words in a web page. The higher the frequency, the more
relevant is assumed to be.
Some search engines, e.g. lycos, do not rely on the meta tags.
Thus, some websites without using meta tags can rank high. Instead,
they may use different criteria to rank your sites, e.g. link
popularity, the hit number, and etc. But many search engines recognize
meta tags. Thus, you still need to use them.
