The most common questions of SEO's will be, Is it important from SEO point of view what kind of extension has page html, asp, cfm, php … Can it make your web site pages be more visible on search engines with a specific extension or not?
Many of us are familiar that shouldn’t build websites using Flash and JavaScript, coz Google can't read it. It looks really cool, but Google will never find such websites.
I got an explanation from one of the expert, follows.
The extension is irrelevant to Google, but it is very relevant to the workings of your site. .html is what Google actually sees and reads, but PHP, ASP and CFM are all made to output html. The real difference lies in the technology. ASP is a scripting language also unstable and not secure. CFM or ColdFusion is a Windoze application, so it runs a Web server application on top of Windoze. It can also be a bit expensive to license depending on the demands of your site. PHP is free. It can run on Windoze, but why. It actually runs as an extension of Apache. In that environment, it is very stable and very fast. A LAMP (Linus/Apache/MySQL/PHP) installation is a common platform to use, but I prefer to run Apache, MySQL and PHP on an OpenBSD server. OpenBSD is by far the most stable and secure platform around. Linux will be fine for many applications.

HTML Validation is the process of checking the document for compliance with web standards and bug search in html code, so the document is considered to pass the validation when it has been checked for errors, and a validator has no remarks to the code.
At the end of html validation process you will have a page without visible errors and your website will appear nice in any browser. This should be done at SEO stage doe to several reasons:
There are many advantages for doing page validation – pages get the structure becoming a web-standardized document; for large sites this will simplify editing and creating new pages. But please remember that users are mostly interested in the content rather than the code changes.
So pay attention to the content making it popular and interesting, but do not forget about the code validation & optimization and marketing features that your website more popularity.

For the last several months, a large team of Googlers has been working on a secret project: a next-generation architecture for Google's web search. It's the first step in a process that will let us push the envelope on size, indexing speed, accuracy, comprehensiveness and other dimensions. The new infrastructure sits "under the hood" of Google's search engine, which means that most users won't notice a difference in search results. But web developers and power searchers might notice a few differences.
Some parts of this system aren't completely finished yet, so we'd welcome feedback on any issues you see. We invite you to visit the web developer preview of Google's new infrastructure at http://www2.sandbox.google.com/ and try searches there.
If you want to get high rankings on Google, it is necessary that many other websites link to your website. This is something that most webmasters know. What many webmasters still don't know is that a website that has only a few inbound links can outrank a website that has many inbound links.
Why many backlinks alone are not enough
If a website has a high number of inbound links, it does not automatically rank highly for any keyword.
Google specifies the position of a website in its search results by on-page factors and off-page factors.
On-page factors are all factors that can be found on your web pages:
•Did you optimize the web page for the targeted keyword?
•Can search engines find all pages of your website through the links on your website?
•Is the HTML code of your web pages error free so that search engine spiders can easily parse your pages?
•Does your robots.txt file allow search engine spiders to visit your web pages?
•Are your web pages free of all spam elements (no hidden text, no sneaky redirects, no keyword stuffing, cloaking, etc.?
Off-page factors are the factors that cannot be found on your web pages:
•How many websites link to your site?
•Are these links from related high quality pages?
•Do social bookmark websites link to your site?
•Do the links to your website include the keywords for which you want to be ranked highly?
All of these factors are important if you want to get high rankings on Google, Yahoo and Bing.
How to meet Google's requirements:
If you want to get high rankings for a special keyword, you must optimize one of your web pages for that keyword. If one of your web pages has been optimized for a keyword, then Google will return it in the search results.
Unfortunately, there are many websites that target the same keywords as your website. If more than one website has been optimized for a keyword then Google will list the web pages with the best inbound links in the top 10 results.
For example, if 20 websites have been optimized for the keyword "green widgets" then the website that has the most inbound links that use the text "green widgets" as the link text will get the best position on Google.
If your website meets all on-page requirements and has the right kind of links (which does not mean that it must have the most links) then Google will list your website on the first result page.
There are many ranking elements that influence the position of your website in Google's search results. The more elements meet Google's requirements, the more likely it is that your website will be listed on Google's first result page.

A New feature of Adwords:
Those who use this regularly may know this feature. recently added to google adwords. That is both keywords and placements can be targeted in all AdWords campaigns. Use both to get better control and pricing power on the content network. Previously these both was on either/or option.
What can you do with keywords plus placements?
Bid more or less for specific placements. Let contextual targeting with keywords place your ads across the content network, while you set placement bids for sites that have a special value for you.
Selling soccer shoes? You might bid $1.00 for clicks from any content network pages that match your keywords, but $2.00 when those clicks come from a soccer fan site that's converted well for you in the past.
Show your ad only when both keywords and placements match. You'll get the benefits of keyword targeting while also limiting the places where your ad can appear.
For instance, set your campaign to appear only on your favorite soccer fan site, and only when the site content matches the keyword soccer shoes. You may see less traffic, but AdWords contextual matching will help make sure your placement pages are highly targeted.
Placements are always optional. They're an advanced feature with no impact on your search network advertising. You can add keywords or placements to existing ad groups, or you can leave those campaigns as they are and create new ones with keywords plus placements.

News Search Sites
These may not be the places you want to go to find regular sites to keep up with (although they could), but they are great places to search for keywords related to your niche and find current relevant news articles.
Visiting sites like Google News, Yahoo News, or even WebProWire should be part of your daily routine to stay as up to date as possible on what is going on in your niche. These sites index new articles constantly.
