I have just done a round up of my several hundred domains to see what they are acheiving search engine wise and I have been pleasantly suprised, especially in the mobile sector. I recently started well just before Christmas on shifting my traffic from 95% ppc 5% seo to around 50/50.
I have opted for adding some well written content, tinkered with copy as well as aquired links through exchanges and primarily through premium placements on related sites. In the past I have achieved number 1 rankings for search terms in the telecom industry (around 3-4 years ago). I am happy to say the sites are still rocking out at the top off google and yahoo however if you read up on many of the seo blogs on the net they suggest that there has been a shift from on page SEO to buying up any link that looks remotely like it might pump up your popularity. I have to disagree.
After working and talking with many so called SEO experts and affiliates most agree with me that on page seo is still very important anything from perfect ad copy, titles and header tags to cross linking between pages as well as a good structure. One of the main factors that have affected my rankings recently is the age of the site. If the site has been around for all of 5 minutes is often natural to see google tinkering with where it should go in the index although frustrating for people like myself who tend to start up 600 projects a week this does not matter as by the time I get round to building the ultimate site based on a particular niche my domain has matured like a fine wine.
Recently Kirsty from Affiliate stuff has written about the pitfalls of affiliate marketing when starting out and I have to say for the main I agree, I do think that having several projects on the go at a time is fine as long as you manage to get them up eventually. The affiliate mind has to be open to all new possible ways of making money online and by shutting yourself into one project at a time someone else may fill the gap you intended to. Just last week I saw a domain I liked available but instead of buying immediately I just put the idea to one side and 4 days after I found it it had been registered however I only found this out on Friday evening and have since bought up 60+ domains about similar niches so that is me busy for the next month or so.
