The single most important aspect of an SEO friendly page is the quality of the content. If you present the visitor with what they are searching for in a well presented, original and quality form, while not trying to trick them into clicking on millions of ads, then you will be geared up for long term SEO success, whereas others will fall victim to the ever increasing algorithm changes. All the other stuff, while important, is secondary to high quality, original content that answers/helps the visitor with their search.

To make site seo friendly here some few suggestion from me are:

1). Choose relevant layout for website
2). Create title, meta tags and h1
3). Track site
4). Optimize the content with good keyword density
5). Make proper navigation through internal linking
6). Create some social networking profiles and make the button on site

The some important factor of site more SEO friendly
Use table-less CSS
Don't use JavaScript & Flash
Use heading & sub-headings with your keywords
Use Breadcrumb navigation
Keep the Sitemap page
Keep the Social Bookmark sharing button

Besides the usual On Page and Off Page, you need to make your site user friendly as well. Facebook and Twitter are usually not really professional business wise use LinkedIn as well to get more serious minds connected to you as well

right targeted keyword, call to action and strong internal linking can help a lot.

structure is very important so make sure you cover all elements in the beginning. make sure the global nav bar is keyword focused, url strings are keyword focused accordingly, the cross linking is very important as well as all the other onsite elements such as professional written headlines that gets click throughs, meta descriptions etc..
