A backlink report tells you that a link was observed. You still need to understand why it's there. Majestic specializes in link analysis. OppAlerts includes link reports alongside prospect, contact, coverage, content, and search research. The useful comparison is what each tool helps you do with that link information.
Imagine an industry association links to three of your competitors. Are they members? Did they sponsor an event? Did they publish resources the association recommends? It's the same referring domain in every case, but each answer changes what you might do next.
OppAlerts publishes this comparison. The vendor details come from research done in September 2026. Check the current plans before you buy. This article didn't measure either backlink index, so it doesn't rank them by size.
Work out how much link data you need
Majestic separates its Fresh Index from its historic index and lists analyzable backlink allowances as API AnalysisResUnits. The researched tiers showed one million, 20 million, and 100 million. Choose the index and allowance based on whether you're investigating current links, historical links, or both.
A million analyzable backlinks doesn't give you a million suitable publishers to contact. One large site can account for many of those records. You still need to understand why it links. With that industry association, more records may help you understand the relationship, but they won't change a membership requirement.
The Majestic plan page reviewed focuses on link analysis. It doesn't describe AI recommendation research, content scoring, or news monitoring within that scope. Bring those into the comparison if they're work you actually need to do.
OppAlerts doesn't sell link data by row volume or publish a comparable crawl figure. If your requirement is a large number of analyzable backlink records, those figures don't establish an equivalent OppAlerts allowance.
Read the page that links to your competitors
OppAlerts Link Gap compares your site with competitor sites. It finds referring sites with observed links to competitors and no observed link to you. From there, open the association's page and see whether those companies appear as members, sponsors, or recommended resources.
If those links come with membership, find out whether you're eligible and what membership requires. A general link request won't address that. If the page recommends resources like yours, read the selection criteria and see whether you have something suitable to contribute. The report shows you the gap. The page helps you understand what to do about it.
Site Info can help you find the association's available published contact pages, email addresses, phone numbers, and social profiles. These are stored website details. Contact availability varies, and you still need to check the current instructions.
Brand Unlinked Mentions gives you another place to start: a stored page that names your business without an observed link. Open it before asking for a change, because a link may already be there. Monthly PageRank history shows domain and host measurements from the link graph. The host chart uses the larger available bare-host or www value each month. Those scores and changes over time don't establish why a publisher links.
Look at the research around the link report
OppAlerts also lets you search for prospects by meaning and opportunity type, research indexed news, blog, and podcast coverage, and research which businesses AI models recommend. Content Optimizer compares your draft with up to three selected categories and identifies missing phrases. Campaign descriptions, brands, and competitors give context to campaign research. The individual tools still use their own inputs.
Which one fits your work?
Look at Majestic for the fresh, historical, or API-based link analysis you need. OppAlerts adds publication and opportunity research around observed links. Work out how many records you need to analyze, then what you need to know before a publisher is worth approaching.
