The title tag is generally accepted that the title tag had, has and surely will have a great amount of importance in the eyes of a search engine. So be sure to make it descriptive for your site, unique for each of your page and also readable. Again, a factor with very little controversy around it and that is considered to have a big significance for your SEO. In short, if you want to rank well for a specific key word, you need to create good and quality contest related to that key word. Having content that has been copied from another older and more significant website will get you nowhere. You will get banned and it will probably take a long time until Google decides to take another go at your website.

Be very careful on how you link to your internal pages. Choose descriptive anchor text and make sure every page is available within 3 clicks from your home page. Also, an internal page linked from your most important pages will probably rank pretty good, while a page buried deep inside your site will have a hard time getting crawled and indexed. Your website age seems to play a smaller role in Yahoo and MSN algorithms, as new but content rich website seem to be able to rank well soon after they have been indexed. With Google, it's an entirely different story, as it seems to prefer older domains, even though their content is not as good as new websites. Alot less valued than in the past, because of the spamming it got, the description tag is still a tag to use because it has a bit of influence on the search engines, and even more, it may entice the people who search for your key words to click on your website.
