Puertas traseras en los buscadores
Hoy, mientras buscaba información sobre un plugin de Photoshop, me he topado con la página web de LeoTheMasteR y en ella el siguiente post que puede ser de interés para bloggers preocupados por el posicionamiento:
Pay-Per-Click-Info is a site that helps you determine where the “sponsored links” come from in the various search engines. For example, looking at AltaVista’s sponsored links — are they coming from Overture, where if you pay to be in the top 3 positions, you can then be in the top results at AltaVista? If you want to try to buy top billing at various search engines, this site will help you figure out how. If this subject interests you, be sure to read their Back Door to the Search Engines Guide.
Another good place for information about the relationships between search engines and pay-per-click search engines, is here - download this PDF from Bruce Clay: Search Engine Relationship Chart. Click on any of the search engines on that chart to see where the results displayed actually come from, and a wealth of other info about that search engine. Very helpful data if you’re trying to crack into or improve a ranking at a particular search engine.
Here’s another interactive Search Engine Relationships Chart that shows the same kind of information and may be updated a little more frequently than Bruce Clay’s report.
