Aaron Wall (born 1979) is a writer and search engine optimization expert. He is a frequent speaker at the Search Engine Strategies, and PubCon conferences.

In 2005 Wall was sued by Traffic Power for defamation and publication of trade secrets. According to Wired Magazine, Traffic Power had been "banned from Google for allegedly rigging search engine results." The case was watched by many bloggers because it addressed the murky legal question of who's liable for comments posted on blogs. The case was dismissed for lack of personal jurisdiction, and Traffic Power failed to appeal within the allowed time.
