Had you read my article on top search engine placement, the necessity of getting top search engine placement for your content on your own website rather than that on other websites, would have been clear to you.
The emphasis in this article is to identify how you can literally "have your cake and eat it" by having your content placed on these Web 2.0 properties and other high ranking websites/article directories, gain the advantages resulting therefrom and still get your own website content to attain top search engine placement.
* Place content you intend to syndicate, first on your website or blog.
As a result of this, you become labelled as the authority for such content on your website or blog, if it becomes unclear as a result of duplication of such content on other websites.
* Insist on having a link back from the other website directly to the same article on your own website.
If you were submitting articles for example, for most article directories, you can insert at least two links in your resource box. While one link can be directed to any inner page you find relevant or your home page, another should be directed to that same article on your website.
Let us read what Google has to say on this
Syndicate carefully: If you syndicate your content on other sites, Google will always show the version we think is most appropriate for users in each given search, which may or may not be the version you'd prefer. However, it is helpful to ensure that each site on which your content is syndicated includes a link back to your original article.
* Another approach to achieving the same objective, though more impractical is to ask webmasters who use your content to use the no-index meta tag.
Again, let us hear what Google has to say on this
You can also ask those who use your syndicated material to use the no-index meta tag to prevent search engines from indexing their version of the content.
* While for short term gains you may backlink to your content on other websites, the bulk of your effort should be at backlinking to your content on your own site if you are not to be short sighted.
* Do a linkwheel for as much as possible of your website content that you have equally placed on other websites.
Starting from your website, you can as an example link the same or similar article on each of the other websites to each other. Your other link can now point back to the same content on your own website, from each of the other websites.
