5) Title & Meta Description Tag:-

Construction of your title tag is one of the most important things you need to do. Each page should have a different title with 2 or 3 of your keyword phrases at the beginning. When search engine results are displayed the title is the first thing people see.
Below the title is a description which will be either be taken from your meta name description content="Description phrase" or from the first sentence on at page. You description should also have 2 or 3 of your keyword phrases at the beginning as so should your first sentence. You should have a different title, description and first sentence on each page. You many also what to try shorter titles with only one keyword or keyword phrase as this will raise you keyword relevance. Also you can consider putting your domain name at the very end of the title.

6) Meta Keywords Tag:
The meta keywords tag is not as relevant as it used to be and some say Google doesn't ever look at it anymore, but put it in anyway.This tag should be different for each page.

7) Author & Robots Tags:-
The Author Tag should contain the name of the company that owns the site. This tag will help you get a 1 position for your company's name.

8) Quality Content:-
Quality content will bring people back and as people always want to tell others about a good thing it will get you forward links from other sites. Your content should be written with your keyword phrases in mind

9) Quantity Content:
The more the better. Just remember your content will need to be both quantity and quality.

10) Changing Content:-
You can do this by hand or with a script. For example you can have a php script that draws five paragraphs from a pool of twenty paragraphs when the content is different each time the php page is accessed.

11) Avoid Dynamic URLs:-
Are you pages via php, asp, or cf? Some search engines may have a problem indexing them. Create static pages whenever possible. Avoid symbols in your URLs like the "?" that you will often find in php, asp or cf pages.

12) Frames:-
Many search engines can't follow frame links. Make sure you provide an alternative method for the search engines to enter and index your site. For more information read Search Engines and Frames.

13) Site Map:-
A good menu system is really a site map. A well constructed menu system that is on each page and contains a link to very page on the website is all you need.

14) Site Themes:-
All of the top 3 search engines look for site themes or a common topic when they crawl a website. If your site is about one specific topic you will rank better than if you have more than one theme or topic on your site. By using similar keyword phrases in each page the search engines will detect a theme this will be to your advantage.

15) Site Design:-
You may think, what does site design have to with search engine optimization. Well if your website has a bad color scheme that is hard to read, is not organized, is a cheesy looking site, then all your site optimization has been a waste of time. Make your site attractive to the viewer, make things easy to find, have you graphic header and menu bar the same place on each page.

These things will keep your visitors on the site and bring them back. A well optimized site with a high search engine results position that is ugly and is hard find information on, will not keep the visitors your optimization has brought to the site.

Put all your presentation code into Cascading Styles Sheets (CSS). This separates the presentation from the content and makes your html files up to 50% smaller. It is reported that the search engine bots prefer this and the more content you have compared to presentation in your file, the better you get rated. Read why tables for markup are stupid for an overview.

16) Robots.txt File:-
While this file is not really required it should be included so that the search engine bots don't get 404 errors when they look for it. Just include the following 2 lines and drop it in the root.
