How do I set specific anchors with specific urls in Scrapejet?

You can do this via the link lock feature.  This is the format: {My Website|My Homepage} {My Site|My Subpage}

There is 1 space between the url and the spin text.  The anchors in spin text are the ones that will be used for the urls they are next to.  You can type in up to 3 urls like this, comma sperated, in the urls box in the upper right.  Alternatively you can place 1 per line in a plain text file and then load that file in the upper right when setting up the profile.

This feature overrides any settings in the profile to use names or anchors etc...

Note: Any keywords placed in the keyword box or loaded in the keyword box in the upper left will be used for harvesting urls to post to.
