Search Trends - Search Engine Marketing

Joel Walsh suggests that Google might have a good writing content filter. He cites the fact that the top listed sites are generally well written and contain fewer gramatical and spelling errors than those at the bottom of the search results. That could be the case, but I wonder if they just make more money than the guys at the bottom of the heap, so they can afford to hire literate copywriters. Or perhaps it's simply an indication of superior intelligence on the part of the top-listed sites, whose smarts also carry over into their link building and other marketing activities. Hmmm. I'm not sure, but I like Joel's piece anyway and he offers some good pointers about writing good content that are very useful regardless of whether Google's alleged "content filter" actually exists.
