SEO experts and internet marketers alike will tell you that the two most important factors in successful search engine optimization are good content and relevant links. But a savvy online business owner should never underestimate the importance of on-site SEO factors as well. Here are ten to which you should pay close attention when you are optimizing your webpage.

1. Description Tags: The description tags on your website will be used by search engines to describe your content on the search engine results page. Thus your description should be compelling to the user so that he or she will click on your site as opposed to the competition.

2. Title Tags: This is probably the most obvious on-site optimization tool, but is often ignored by online business owners. Each title tag on your website should be short and unique, and should contain the keywords for which you are optimizing on that particular page.

3. Heading Tags: Each page should have a heading that uses one or two keywords to describe the page's content. The most important heading should, of course, have an H1 tag. H2, H3, H4, and so on should be reserved for your subheadings.

4. Anchor Text: If you're serious about SEO, then you need to pay attention not only to anchor text in external links, but also in internal links. Your anchor text for internal links should use keywords and keyphrases; otherwise, how do you expect a search engine to reward you for relevance if you don't even reward yourself through optimized anchor text?

5. Filenames: Each page in your website should be named using the keyword or keyphrases for which you are optimizing that particular page

6. HTML Sitemap: Your website should definitely include an HTML sitemap to help search engines when they are indexing your website. If your website consists of a large number of webpages then you should arrange your sitemap using categories. If you just create one long list of pages then you're not helping your visitors navigate your website, and usability is really one of your ultimate goals.

7. XML Sitemap: You should have an .xml file that contains a list of the URLs used in your website. This file should then be submitted to the search engines. This file will help search engines when they are trying to index your website.

8. Navigation: Instead of linking from every page on your website to every other page on your website, choose the most important pages from which to link from your homepage. The categorize each of your other pages to go with each of the most important subpages that you have just chosen. This helps the search engines understand which pages you consider to have the greatest value.

9. No Follow: Let's say that you want to link from your website to some helpful information you've found on another website, but that you can't vouch for the entirety of the website to which you are linking. Simply add a no-follow attribute. This tells Google to ignore your link, which is helpful if it's possible that the overall quality of the page to which you're linking is not terribly high.

Content: As mentioned before, on of the most important elements of on-site SEO is content. But unlike link creation, you have 100% control over the content on your page. The key to content is to write relevant, unique, helpful copy that your visitors will find engaging and useful. Equally important is updating your page with fresh content on a regular basis. Search engines pay attention to pages that update content frequently, so this is one of the most important things you can do to get spiders to notice your page. The caveat is this: don't just add content for the sake of adding content. Make sure the information you're adding is relevant and useful. You waste everyone's time by updating your page with random content that isn't much help to anyone.
