I've compiled 12 ideas that have given me great results. The first 3 are listed here. The rest of the list and the complete article can be found on my site; http://www.HelpForWebBeginners.com/SEO/directory-submission.html
- Always make sure the link being given is SEO friendly.
The page should link directly to your URL and encourage search engines to both index and follow all links on the page.
- Always read and comply with any listed submission guidelines. Directory owners recieve so many spammy and poor submissions that they rarely give a site a second chance. Take the time to play by their rules - after all they are giving you a backlink with the link text of your choice for free.
- When possible, take the opportunity to submit a link to an interior page (deep link).
People will often trade links for homepages, but it is harder to get links to interior pages. Keep in mind, deep linking is often against a directory's guidelines and submitting a deep link can get your site permanently banned if the directory owner does not accept them. I recommend submitting pages that appear on your main navigation menu.
I've seen great results with directory submissions and have literally watched my websites climb in Google and Yahoo using this technique. Hope this helps some of you.
