Xfrog is also a procedural/parametric modeling software specifically designed for generating plants and trees. It also comes as a plug-in for Maya and C4D, if you make a creation graphs inside of this software then other users (hoe have the plug-in installed) could also use it.
So you would have parametric capability's for those plants (can change things/look of the plants)
You could sell these creation files/parametric plants over here.
The software can also output OBJ files for import to all other major 3D software (does not include the parametric capability's).
It is software like Speedtree, Plant Factory and Exlevel GrowFX.

Generative content/creation graphs is the way of the future (especially for nature scenery), allot of people are going to love these generative objects/files more than the regular static meshes hoe have no parameters to change quickly.
If you have a good creation file and know the parameters well, then it is quicker to change some parameters to get the look you want then browse the web to find a model that looks the way you want.
The fact that the keyword suggestion shows "xfrogplants" is a sign there is some meaningful correlation, in this case you can safely assume there are a good amount off xfrogplants already present and people have looked for these plants/creation files previously.
The keyword suggestions are coming from a pool of previous keyword entry's and database correlations, they provides information about watt is currently present and previously asked.
In short, the engine knows you entered plant/ tree and presumes there's a chance it will involve xfrog plants and so provides the suggestion.
It is not attempting to advertise competition if that is what you think lol ;-)
It is indeed a seller but is also selling the same products here.
You are free to have/own an online shop of digital content and sell that same content over here.
