What I do is, I create 7-10 web 2.0 properties and treat them as if they are my own sites. It's not easy writing unique content for ten sites, so I write one good article, 1000-1500 words using LSI and keyword variations.
Next, I "hand" spin the original article. I literally go through the article and try to create three variations of each small segment of text, to the point were a single sentence might have three or four spintax segments that each have three variations. I do the same thing with the H1/H2/H3 tags. The advantage here is, you will probably know your niche better than any commercial spinner, AND can use appropriate sentence structure variations that will look/read better than a commercial spinner.
On a thousand word article, it usually takes me a good hour to go through and manually do the spintax. After that, you can find a free online article spinner that will take an article in spintax format (without adding any additional spintax), then spin it for the 8-10 web 2.0 sites. I insert different images, at different locations in the paragraphs. I use page title variations. I add link(s) to my site, some to the home page, some to important inner pages, from different keywords in different paragraphs/parts of the article, so they are not all the same.
A few days later, I will write another article, then manually spin it, then add those to the primary web 2.0s. After that, I try to do one or two a month and keep building them up.
Use these as your "primary" web 2.0 properties. Some people proceed to buy up GSA/Wikilink spam links. What I do, is order the cheap web 2.0 packages and point those to my "primary" web 2.0 properties. Sort of like a "double buffer." The main reason I do this, is I want to protect the time I've put into my "primary" (quality) web 2.0s, so I buy web 2.0 packages to those, then I can spam the cheap web 2.0s that point to my primary 2.0s without worry of losing my primaries, if they get whacked.
The next thing on my list, is to build a "primary" web 2.0 network of 7-10 different web 2.0 properties, then buy 6 web 2.0 packages to point to each of those primary web 2.0s. The idea being a massive passdown of authority to a single set of primary web 2.0s that point to my money site.
