Hi g2311,
First:
To remove a link, simply remove it from the list you have created. It helps to keep the list sorted by sort-of-alphabet. I know the guy over at GadgetGear.nl managing it has 300+ entries in his list.
Second:
The objective is to make cornerstone content creation as easy as possible. If you’d want to target the same word with multiple URL’s and specify that per story, I would have to build a pretty complex administrative environment to handle that.
I would even debate that manual link management could be faster in such cases as the load on the database would be at least as heavy or maybe even more heavy. This tool really built for ease of use.
Now, there is a workaround as the list can handle phrases as well. So you can use that same keyword and combine it with another one.
Let us take a look at the GadgetGear.nl website as an example again. They have defined URLs for Google, Google Glass, Google Home and Google Assistant. All four cases receive a different internal URL at they are different services from the same company.
As the system executes the list topdown, the order of the list specifies the Google URL after Google Glass, Google Home and Google Assistant. This to avoid the first combination of Google Glass to have a link on Google to all Google content but not on Glass to link to Google Glass content. So that’s the only workaround I can give you given the scope of delivering an easy to use plugin.
This also explains why I don’t sort the list by alphabet myself. You will want to make exceptions in the order of execution for this list.
On GadgetGear.nl the plugin is used for increasing internal traffic and time on site. The plugin generates 18% more pageviews and adds 13 seconds to the average time on site (I only have that combined number).
