THE BASICS OF SEO FOR WEBSITE CONTENT OWNERS
- Use a meaningful page title in the tag.
- Keep HTML markup semantic and simple.
- Avoid tables except for showing tabular data.
- Avoid reliance on images: use ALT tags describing an image’s content for both 508 compliance (for the visually impaired) and for search engines.
- Use background images rather than images in the markup to represent a site’s name or page’s title.
- Avoid image maps; instead, use list items with background images through CSS.
- Maintain good page structure with headings being hierarchical and properly used (ex. H1 > H2 > H3)
- Try to place most of the page’s main content towards the top, just below the page’s title.
- Make sure pages are as standards-compliant and accessible as possible.
- Use tools such as the w3c validator for HTML standards compliance and Cynthia Says for compliance with 508 Standards.
- Avoid having many broken links on your site: Use 301 redirects for pages that have moved so search engines update their entry.
- Use 'canonicals' whenever there are multiple/duplicate pages or URLs that serve the same content to avoid confusing search engines. The reason for this is that some search engines punish (from an SEO perspective) sites that have duplicate content. As always, your objective, when creating URLs and links should be to direct users to the right URL. This page on google's webmaster support pages discusses this in more detail.
- Publish a site map so users and search engines can find deep or hidden pages that may not be referenced elsewhere with real content.
- Use a robots.txt file on your server in conjunction with Google Webmaster Tools to verify that your robots.txt file is set correctly and allows search engines to crawl a website.
