I have been using Vispr for all my WordPress sites, including my clients' sites, and it works great even after ownership changes. I was initially scared because such changes often end poorly for legacy customers like me, but I was wrong. The support is still excellent, and the process remains effective. As long as you have everything clear, there should be no problems. It only works on WordPress, which is not a surprise; that's the main rule from the beginning. There are some limitations, such as blackhat sites and sites that you wouldn't want your kids to visit, as well as some restrictions with hosting providers that have a bad reputation. If you clearly understand these requirements, you should be able to run it without any issues. Again, I am a satisfied customer and thrilled to see my sites ranking well with the help of this backlink platform—no more bad backlinks, only the ones I need.
