Getting Yahoo! Directory Listings

The Yahoo! Directory, a somewhat lesser known part of Yahoo!, works in pretty much the same way as the ODP, except that it is privately maintained Sites added to the Yahoo! Directory tend to end up in the Yahoo! index, as well as other important search indices, often with high ranking in response to searches related to the Yahoo! Directory category for the site.

To suggest your site for inclusion in the Yahoo! Directory, open the Yahoo! Directory's home page, http://dir.yahoo.com/.

You can also find the Yahoo Directory by opening the main Yahoo! home page, selecting Directory as your search category, and searching for a term. The search results you will be presented with are from the Yahoo! Directory (not the Yahoo! Web index), and the display will show where in the taxonomy you are, so you can browse through related categories.

Wikis

Wikisand particularly the Wikipedia, found at http://www.wikipedia.org/are community-based knowledge systems. The Wikipedia, and other select wikis, turn out to be excellent grist for the SEO link placement mill. Anyone can add content to a wiki, and the content tends to be authoritative. A link to your site strategically placed in a Wikipedia article may generate considerable traffic, and is likely to boost your sites standings with Google and other search engines.

The note of caution here is that placements should be relevant. Irrelevant spam links that don't have anything to do with a topic in a wiki are likely to be deleted by the community quickly. In addition, SEO has grown up from the early days, and practitioners realize that what goes around comes around, and that spam is evil. In other words, craft wiki text and links with care and make it valuable content for the wikiand, in doing so, better serve your SEO goals.
