Authority Site Link ROI Calculator

It's an educated estimation. The real Google algorithm has hundreds of factors. This calculator uses a simplified model to demonstrate the directional impact of authority. The actual result will depend on many other factors, including the link's relevance, placement on the page, and the overall competitiveness of the keyword.

Domain Authority (DA) and Page Authority (PA) are metrics developed by Moz. Domain Rating (DR) and URL Rating (UR) are similar metrics from Ahrefs. You can find these scores using their respective SEO toolsets. They all operate on a 0-100 logarithmic scale and are the industry standard for estimating a site's or page's authority.

Not necessarily. While higher authority is generally better, relevance is just as important. A highly relevant link from a DA 50 blog that is perfectly on-topic for your page can be more valuable than an irrelevant link from a generic DA 80 news site. The best links have both high authority and high topical relevance.

Link equity is a search engine ranking factor based on the idea that certain links pass value and authority from one page to another. A link from a more authoritative and relevant site passes more equity and has a bigger impact on your rankings.

Costs vary dramatically. You shouldn't "buy" links directly. Instead, you invest in strategies that *earn* them, like Digital PR campaigns, creating link-worthy data studies, or guest posting. These campaigns can range from a few hundred to many thousands of dollars, depending on the scale and target publications.

A direct ROI calculator measures the value of referral traffic (people clicking the link). This calculator models the *indirect* ROI, which comes from the link boosting your search engine rankings over time, leading to more organic traffic. The indirect ROI is often much larger but harder to measure.
