Do You Want Your Site Visible on Search Engines?

Here are few tips to get rank top on best search engines.
Use your keyword phrase in headlines: Headline tags (h1, h2, h3, etc.) are a great place to use your keyword phrase and secondary keywords. Search engines recognize that headlines are more important than the surrounding text, and so assign greater value to keywords found there.
Use your keyword phrase in anchor text of links: Link text is another great place to put your keyword phrase. Links stand out on most Web pages, and so are given higher priority than surrounding text.
Ask other people for links to your page: A great way to get inbound links is to simply ask for them. But remember that excessive cross-linking can be viewed as spammy, so be careful about trading links or otherwise buying links on external sites.
Try to get your keyword phrase inside incoming links: Inbound links are a great way to improve your page rank. But you can't really control how people link to your pages. Chances are they won't use a phrase that has anything even remotely close to your keyword phrase. Remember that they are doing you a favor by linking to you. If it makes sense, you can ask them to change the text of the link, but be careful, as people can be very touchy, and you might just get your link removed.
Try to get links from reputable sites: Reputable sites that link to you will increase your reputation. After all, if a reputable site feels that your site is valuable enough to link to, that means that your page has more value. You can tell if a site is considered reputable both by how high it appears in search engines and it's Google PageRank. Also, .edu sites have a higher reputation because they represent schools and universities.
Try to get links from similar sites: Inbound links from sites similar to your own are important as well. This indicates that your site does have content related to that topic. Plus, it indicates that your competition finds your site valuable, and that gives your site more credibility.
Try to get links from .edu, and .gov sites: Sites that are on .edu and .gov top-level domains have a large amount of credibility because they are very difficult to get. So if you can get the designers of those sites to link to you that gives your site more credibility as well.
Create as much content as you can: Content is king. The more content you have on your site, the more there is to be indexed and appear in search engines.
Keep your site live as long as possible: Older pages (at the same domain) will rank higher than newer ones.
