How much can I increase traffic on my site

I have several sites, some have 1000 uniques per day, other 50 or 100.

If I use ultimate demon or magic submitter, how much can I increase the traffic?

Especially I am ranking for a keyword I am currently on the 3rd page and I would like to get it to top 5

The site has like 400 uniqes per day

What you predict will happen if I start using scrapebox again ultimate demon? Can I get to top 5 and increase traffic to like 1000 per day?
