The only bow to SEO that I made was establishing a list of keywords when the site was first established, but as Google and search engines no longer use lists of keywords I haven’t bothered to keep the list current for years. The keywords are probably still there buried in the HTML code somewhere, vestiges of a bygone era.
Many of the so-called SEO experts are just shams. Google is constantly revising it’s algorithms, and most honest SEO advisors will tell you that the best way to improve your search ranking is to write clear, compelling prose, that if you contort your writing to meet some algorithm’s requirements you will only succeed in lowering your ranking as your site becomes unintelligible. Although they do run statistics on what words you should use. I remember one example from my days in Silicon Valley was that we were advised to use both “laptop” and “notebook” when writing about our products for that kind of PC.
