I saw a lot ppl complaint abt auto blog, Content duplicate, google sand box and bla bla bla ....
I run a few (<30) auto blog and some turn out to be E-commerce site, with all different method but at the end all work out same way ....
Technique i use:
Content rewrite script.
Auto social submission.
Pic name change.
Btw with all above script doesn't means i rank well in serp or sandbox or deindex, some site rank better without doing anything (100% copy content), still work and no sandbox or deindex.
Must do list and script use for my site.
1. WP (i like their easy setup, on page SEO and a lot freelancer for custom script).
2. All in one seo.
3. SiteMap generator.
4. Auto Tag.
5. Exact Match Domain (most of it or domain some how related)
6. Submit sitemap to google, yahoo, bing.
7. Submit directory by Digimas (free version)
8. Adsense. (i found my site index faster (first index) with adsense.
attachment is my latest auto site stat :
Feb 2010. 0 traffic
Today Oct 134k UV (monthly)
Growing rate 15%-25% (base on monthly UV)
Source of Income:
Income Adsense : 5 - 25 daily (taking most of it out soon)
Income 1500. (local AD provider, they pay me to grab their site content)
Income 1500-2500 Monthly (estimated, local banner ad start next month or end of the year)
90% Auto (one server for scrapping now)
5% When i run bulk Delete. (yes i can use cron job, but still need to pay abit attention on it)
5% Off page SEO on my main page.
So for me, auto blog is working, just depend on concept and marketing.
