Started with AVS, free sites and some gallery submission in '99, kept that shit up on and off for several years, AVS kinda died off, so free sites and galleries was still the bread and butter. Never got around to building up any larger TGP/Linklist etc kinda site.
Now day's It's a combination of it all including 100+ own domain blog's that get update way to seldom.
SEO is combined into the blog's and free sites.
