1.) If any of your pages have the same title, change the titles to reflect the content of the pages. This is good for SEO because the search engines prefer pages with different names, and people are less likely to click on a search result if it has a generic title. Avoid using titles over 60 characters long.

2.) Add brief, descriptive “ALT text” tags to your site’s images. Internet users with text-only browsers will see this text in place of graphics. Its good for SEO because search engines can use this text to interpret the subject of an image, giving them a better concept of the page’s content.

3.) Test each of the links on your site to make sure they still work. If any produce errors, either replace, update, or remove them. This is good for SEO because some search engines will downgrade your site’s search ranking if it has too many outdated or incorrect links.

4.) If any of your pages contain information on more than one distinct subject, divide them into separate pages. For example, a page that lists every product a company offers should instead be split into multiple product categories (unless all of the items are very similar).

These SEO tasks can be accomplished in less than 2 hours for many web sites. However, they do not address other important SEO issues like keyword density, META tags, link building, and site maps. If in doubt consult i) an experienced search engine marketing agency, or ii) an internet marketing agency with experience in search engine marketing.
