Many thanks for the questions; i will try to answer in the order you asked, below:
1: 1 Url and 1or 2 keywords. I normally use the links in the resource \ author box like this : and then inside the article i place 3 specific anchor links to fit with the article. Normally it is only the mediawiki's that allow the links in the article, so 3 article links and 40 media wiki sites mean 120 links just from Media wiki.
2. Yes i spin all article when i do the submission. No please don't add any html in the article, i will add the links myself, otherwise they end up getting spun.
3. No i do one submission at a time, so 20 submissions i can do in one day if you provide the articles, if i need to scrape then i will do it over 2 days -- i can even do it over 20 days - meaning 1 submission every day for 20 days. -- Its really up to you just tell me how you want it done and if possible i will work around your request or give a alternative suggestion.
thanks for your prompt reply in patience. one more question is that need i insert the keyword when i submit the article to you, or will you random insert the keyword in the article? and one article one submission, right?
