yeah you’ll get initial results but there’s a large chance everything gets deindexed down the road, potentially impossible to recover – HCU sitewide penalty is a thing. Have done my own single site programmatic projects that worked well for awhile then got hit months later SUPER hard to reindex pages, and partnered on another programmatic parasite project 250k+ posts across thousands of accounts and traffic was awesome for awhile – and then it completely dumped after about 4 months. Not saying it can’t work – just have to be willing to take on the risk and understand the nuances.
