Yes and no - it depends on how the traffic is channeled to your site. If they are channeled wrongly, then no it will not contribute to your overall SERP ranking. But if done correctly, it will definitely boost up to 1 page per effort.
So if yes, these traffic must be natural in appearance to google - it must have unique IPs and preferably residential IPs, and the computer info, hardware info, all must be different (different unique user agent).
If the seller is lazy, they could be using a software that uses the same IP over and over, and with very bad user agents, and these have already been found out and it no longer contribute to the SERP ranking factor.
