The videos are the best resource as
kingtigerx suggests. It can seem overwhelming at first but it's relatively easy to get to grips with.
Forgive, me, I don't know what level you're at in terms of understanding basic HTML etc. So....it largely depends on what you're trying to achieve with it.
See you can use it for data mining, list building etc. You can do this either by scraping the search engines or pay for the Yel scraper but you do need to start to understand how to drill down and refine what Scrapebox presents to you.. For example, I am only interested in UK info, but even though I do everything I can to keep things UK e.g. "%kw% ".co.uk" OR ".com" and add the target towns, it often still throws results from overseas into the mix.
This is where the page scanner can be your best friend.
Does anyone know if search operators kind of work in Yel with this being a proprietary platform?
It's much more than a data tool, it literally is the Swiss Army Knife of web tools.
I try and watch a few of Looplines videos a day at the minute, it takes practice and patience but you can get proficient fairly quickly.
