I have been involved in search engine marketing since 1996 in some extremely competitive marketplaces such as real estate, retail, and online education and it is amazing to me how much search engines and search engine marketing has evolved over this time. The days of making an SEO tweak to your site and submitting to Infoseek to see in 24 hours if you rank in the top 10 are long gone. How about the days of getting into the directory section of Yahoo for free or what about that site Goto.com where $1.00 got you 20 clicks to your website? Like they say all good things must come to an end.
