That`s a valid point. SEM (Search Engine Marketing) is only one part of online marketing. Search Engines are a percentage of where traffic comes from. With that said, I`m not sure why a business wouldn`t integrate SEM at some point but it`s possible to build traffic in other ways as well as offline too. Consistent marketing for long term growth, however, almost always needs to target the engines and directories.
Even though Flash isn`t being read by bots, more recent versions of it export a list of words being used in the .swf file. I have my doubts as to how the engines are warming up to this. I`ve been meaning to research this more. It used to be that PDFs, another binary format, weren`t indexed, but are now by Google and probably other engines.
Another factor your client may not be considering is content management for after the site launches. Depending upon the frequency of updates, an almost completely Flash site may not make sense without spending $ on database integration.
