Ahrefs and OppAlerts both provide link research. To compare them, follow a real finding into the work you want to do next. OppAlerts publishes this page, and we haven't measured the backlink indexes against each other.
Imagine three publications link to a competing manufacturer. One tested its product, another lists it in a directory, and the third published a technical case study. Open the pages to understand those relationships and decide where your own business could contribute.
Choose the data your investigation needs
Ahrefs provides backlink and historical SEO research, Site Audit, and API and MCP access from Lite. The reviewed Lite, Standard, and Advanced plans include 100,000, 500,000, and 1,500,000 crawl credits, with six months, two years, and five years of history. Enterprise has unlimited history. OppAlerts doesn't audit sites or publish a comparable crawl figure.
Ahrefs Brand Radar also offers prospecting. Its AI Visibility Index starts at $199 monthly and lets you research brands without configuring custom tracking first. That index is purchased separately from custom prompt packages.
OppAlerts' Prospect Index searches by subject and opportunity type. For the manufacturer, you could find publications accepting engineering case studies even without a recorded competitor backlink. Read their requirements to check whether you have the measurements, permissions, and technical details they want.
Published contact records can help locate submission instructions. News research, link gaps, and monthly Domain and Host PageRank history add context. Check contacts on the live site; they aren't verified for delivery. Read the publication to judge its fit. Campaigns supply business context, with separate inputs for individual tools.
Site Info returns stored contact pages, emails, phone numbers, and social profiles. Brand Unlinked Mentions finds collected pages naming your business without a recorded link. News, blog, and podcast records give you more material to research the publisher.
Calculate tracking and team costs
The September 2026 Ahrefs pricing snapshot included 750, 2,000, or 5,000 keywords with weekly updates and 5, 10, or 20 daily AI prompts on one platform across those three plans. Confirm the current packaging.
Additional custom tracking packages were $50, $100, and $250 monthly for 2,500, 7,000, and 25,000 checks. A standard check covers one prompt, platform, and location. Claude uses eight checks per update. You don't need the separate AI Visibility Index to buy those packages.
OppAlerts continually checks for new opportunities. For Ahrefs, count one check per prompt, platform, and location for each update you want, then compare that total with the researched packages. Add locations or heavier check weights to the calculation where needed.
Ahrefs Lite, Standard, and Advanced include one user. Additional users cost a researched $40, $60, and $80 monthly respectively. Five people on Standard add $240 for four extra users. OppAlerts includes team members up to your plan limit. Count everyone who needs access when comparing costs.
Try the functions you expect to use
Ahrefs Content Kit includes AI Content Helper and Grader. OppAlerts' Content Optimizer compares your text with selected taxonomy categories. Try the actual draft in each; neither assessment establishes future search citations.
