FAQ

Questions people ask

Does Byline Leads send an alert the minute a post goes up?

No. It scans daily or weekly and looks at what Google shows on the first page for your searches. A brand-new post usually is not there yet.

That is the point: a thread on the first page is read by everyone who makes that search, often for months, so a good answer there keeps working. For instant alerts on new mentions, a monitoring tool is the better fit.

Does Byline Leads post the replies for me?

No. Each result comes with a reply written for that thread, in its language. You read it, change what you like, and post it yourself from your own account. Nothing is posted automatically.
