SubmitSaaS Domain Rating Calculator is a free SEO tool designed to help SaaS founders and startups estimate how their Ahrefs Domain Rating (DR) can grow through directory submissions.

The tool allows users to select from a database of 700+ directories, filter by DoFollow or NoFollow backlinks, and simulate how different submission strategies impact their DR. It provides real-time projections based on backlink quality, referring domains, and industry growth patterns.

This calculator is especially useful for early-stage startups looking to build their initial backlink profile efficiently. It highlights the importance of high-authority directories, explains how DR works, and offers actionable insights to maximize SEO performance.

In addition to the calculator, SubmitSaaS provides done-for-you submission services, helping founders save time while gaining high-quality backlinks, increasing domain authority, and improving search engine rankings.
