The SubmitSaaS Domain Rating Calculator is a free SEO tool that estimates how much your Ahrefs Domain Rating (DR) will increase by submitting your SaaS or startup to online directories. By selecting from a curated database of over 700 directories and setting your current DR, you can see projected backlink growth in real time. The calculator lets you filter directories by DoFollow or NoFollow links, sort by directory DR, and search by category—including AI, community, launchpad, and software directories. A live selection summary shows the number of chosen sites and a breakdown of DoFollow versus NoFollow backlinks, giving you a clear picture of your potential link building impact. Built on typical DR growth patterns observed from hundreds of SaaS submissions, this tool provides an approximation to help you plan your directory submission strategy and prioritize high-DR sites for maximum effect.
