Hi Jericho,
The indexation rate is relatively good with default options. However, if you make use of our tier 2 options and/or additional articles you can get much higher indexation rates. We can indeed post longer articles to them, but you will need to order additional articles for that (see order form). We would then create one long article instead of using multiple articles.
Let's say I ordered the 2000 and I would get 20 unique articles. Are these articles then spun to post to each of the web 2.0s? If they are do you spin the articles together or are they individually spun?
