Nice little app makes it real easy to keep the site clean and organized for indexing.
So far this app is simple to use and has the ability to exclude URLs out of the sitemap. First app I've found in weeks of searching with this functionality. The developers seem eager to improve and build upon their product as well.
At last, something that resolves all the duplicate pages created by tags and power tools variants filters. Easy to use and install, they even took on a few of my recommendations and installed whilst I was using it! Will report back on any success. Worth checking your site map before and after, then search console to clear up any other duplicate meta descriptions and titles.
