Now everyone knows that you need to choose keywords and meta tags to make your site search-engine-friendly (don't they?). And pages should be 'optimised' BEFORE you submit them to search engines.
Optimising your site for search engines is really not that difficult, but it is important: no-one visits your site if they can't find it on first few pages of a search engine.
A good way of 'getting found' is to choose high-demand low- supply keywords (like "free nokia ringtones"), and to create pages optimised for those keywords. (Obviously, you need to find keywords relevant to your website.) The basic guidelines, below, show you how to optimise your pages - how to make sure your site gets click - but how do you find these profitable high- demand low-supply keywords in first place?
=> USE THIS RESOURCE
Wordtracker is a free tool that allows you to brainstorm keywords and determine which of those keywords (if any) have little competition on net (which are most 'profitable'). You simply add suitable keywords to a basket, and their profitability is determined using AltaVista as search engine (the paid-for tool determines profitability using all of major search engines).
Wordtracker is a powerful tool endorsed and used by many so- called search engine experts. You should use it too, to improve your chances of getting click.

=> THEN STUDY THESE BASIC GUIDELINES
Many of major search engines behave differently to each other when it comes to choosing best pages. Worse than this, though, is that some use meta tags and some ignore them completely, preferring only to rely on page content (with weighting given to words at top of page). Even worse still, search engines constantly change their ranking rules (algorithms).
So understand that these are only basic guidelines. However, they should help your web pages rank better with search engines, *over time*:
