Is there any benefit to using an existing campaign as opposed to a Sellozo-launched campaign?

If you have been running a Sponsored Products ad campaign before starting with Sellozo, you have access to data that Sellozo can manage to quickly optimize your old campaign and create new converting campaigns quickly. When Sellozo launches a campaign, we start with an Automatic campaign to gather search terms related to the product. Then we work our magic and adjust bids, negative keywords, and find the best converting search terms. If you have spent money running a campaign, you have access to valuable keyword data for your products, just turn on the optimizer and Sellozo will do the work.

By choosing to use the optimizer on an existing campaign, this will expedite the process and save you time and money because you don't have to recereate that campaign and start all over again.
