There are very nice and simple written 20 tips on how to improve your Web Site to fit it better to the Google requirements.
1. Title of the page itself is a hot factor in SEO and you will see that Google shows results with titles of pages highlighted. Of course the top page will have a highest PR. Even if you have a good PR you need the title relevancy of the pages.

2. Meta Tags are important - In the semantic wave over the web, the meta tags are of importance because these tags convey the meaning to many search engines including Google but Google uses Page rank as a dominant factor. Still meta tags remain important for other search bots and local searches to index your web site.

3. Use the H1,H2.. HX tags for the titles because the bots look for these tags to determine the title of a paragraph. Its important for SEO.

4. Do not copy content from elsewhere on the web. You know all these search engines are so good at filtering duplicate content and might be your page rank gets lowered by some small factor.

5. You need to give a lot of content to your site’s visitors and it should be of good quality and never choose a narrow topic because you will run out of topics to write on so choose something like what I did Web 2.0 is a very broad topic and I could write tonnes of content on this. Keep in mind that we web masters and bloggers should have innovation as bloodline and keep delivering right content to our visitors.

6. It’s always better to choose a geography specific domain name like .us or .co.uk because these will help you appear in your local searches to promote your business.

7. You need to monetize your niche, You’ll have to pour in content centered around a topic and grow the amount of it. Its the ground where you play and you’ve got to have your feet firm on it.

8. Build a site only on topic that interests you, never start a site because you found someone making money with a site about cars. It might be exciting to start it but in the long run you cannot support the need for quality content that you are expected to deliver out of a topic where you do not have expertise.

9. Google does not index images without alt tag and never forget the image searches from Google,Yahoo and MSN. Create images with alt tags and they carry meaning and name to the images on your site. This will help your site appear in image searches. It will bring you a decent amount of traffic.

10. If you want to make money with adsense or any other contextual advertising network, optimize the ads to make them display relevant ads. Don’t just insert them and ignore.

11. Join advertising campaign like adwords that bring visitors who match your interest.

12. In the context of SEO offer RSS feeds because they bring in other bots that index your site.

13. Submit your site to DMOZ, Google and other search engines. Let them know that you are present. You’ll have to make submission only once because Google will keep crawling your site periodically.

14. Measure your progress by joining Google analytics. Keep track of your visitors.

15. Keyword research about your niche or market is essential. You will not be profited if you fail to do it. Say 30 keywords mean business to you. Use each of them in pages, a keyword can be present 6-8 times in a page, I would recommend this numbers. Never over do it because Google and others consider your page to be spammed with keywords and that is not what we want.

16. It takes a lot of time and effort to start a web site from scratch and its better associate yourself with an company’s website and make your own part of it.

17. Never go for link building scams from web site who claim to increase your PR. Let that happen naturally. Good way of doing it would be commenting on blog posts of your topic.

18. Be patient when you want to search market your site and search engines take a lot of time to index your pages and this time is not fixed it might take from a week to several months to get index and I would say patience builds personality.

19. Do not just rely on search engine traffic for getting visitors. Do marketing by newsletter or join advertising campaign.

20. I think it is not possible to optimize a site for all search engines, doing so for Google will leave Yahoo and vice versa. This is one of reasons why you are not recommended to rely only on search traffic.
