The DA Checker lets you paste a list of domains with their Domain Authority scores, then automatically sorts them by score, categorises them into four quality tiers (Authority, Strong, Moderate, Low), shows a distribution bar chart, and calculates average, highest, and lowest DA across your list. Export the ranked table to CSV for use in link prospecting or client reporting.

The Domain Authority Estimator models your likely DA range based on five key inputs: domain age in months, number of referring domains, average DR/DA of those domains, indexed content page count, and technical health score. It returns an estimated DA range with growth tips for the factors most holding your score back.

The DA Comparison Tool lets you compare Domain Authority scores for up to 8 domains simultaneously. It displays a horizontal bar chart sorted by DA, a gap analysis table showing how far each domain is from the leader and from DA 90, and tier labels for each entry. Use it to benchmark your site against competitors, set DA growth targets, and identify the authority gap blocking page 1 rankings.

The Backlink Profile Checker categorises your referring domains into four quality tiers based on Domain Authority scores and spam flags: High Authority (DA 60+), Mid Authority (DA 30-59), Low Authority (DA below 30), and Toxic (manually flagged). It calculates a profile score, average clean DA, toxic link rate, and distribution chart for your backlink portfolio.

The Link Velocity Calculator shows how long it will take to reach a referring domain and Domain Authority target at your current link building pace, and what pace you would need to hit that target in 6 or 12 months. Enter your current referring domain count, DA, monthly acquisition rate, and targets to get a projected timeline and pace comparison table.

The Disavow File Builder converts a pasted list of toxic domains and URLs into a correctly formatted Google disavow .txt file ready to upload to Search Console. It automatically applies domain: prefixes to domain-level entries, validates URL format, separates domains from specific URLs in the output, and includes a dated file header with your optional case reference note.
