Will a Dmoz listing boost my Google PageRank?
Every link helps. But when assigning PageRank, Google treats Dmoz exactly the same as any other site. It does not give any extra weight to a link from the Open Directory. (This has been stated repeatedly by Google staff, most recently by Matt Cutts in a webmaster chat.) However a link from Dmoz eventually spawns links from its many clones, which adds to PageRank. Since many ODP clones have low PR, the effect may not be as great as is sometimes supposed. The most notable clone is the Google Directory.
