If you review brand coverage, you need to know which sources each service monitors and what happens after a relevant mention is found. Mention watches the web and social platforms for keywords you register and returns the results as mentions. OppAlerts searches indexed news, blog, podcast and web pages for mentions. It also supports link requests, prospect research, contact lookups and content checks.
OppAlerts publishes this comparison. Mention reads social platforms and review sites, which OppAlerts does not.
The dividing line is social coverage, and it runs firmly in Mention's favor.
What each product reads
Mention's FAQ defines an alert as a keyword or keyword set used to search the web and social media. A mention is a result it finds. It supports Boolean search, monitors social media and review sites, and states coverage of a billion sources. That figure is Mention's own, and source counts are not defined the same way between vendors, so it is not comparable with any other number in this comparison set.
OppAlerts reads published pages. Its News Index covers indexed news, blog and podcast content. Its Prospect Index covers stored web pages. Brand Mentions draws on search results, the Prospect Index and the News Index together.
It does not read social platforms, and no OppAlerts report should be presented as social listening. If your reputation work happens on social networks and review sites, Mention covers that ground and OppAlerts does not.
Mention's FAQ states that Publish and Respond have been progressively deprecated. It directs publishing and responding to Agorapulse. If you reply to mentions inside Mention today, confirm what is still available before renewing.
What happens after a mention is found
This is where the products separate. Mention reports the mention and its context. OppAlerts is built around the next decision.
- Brand Unlinked Mentions lists pages that name the business without an observed link to it. Open the current page before requesting a link, because the publisher may have added one since the page was stored.
- Site Info returns the stored public contact pages, emails, phone numbers and social profiles for that site, so the request can be addressed to a person rather than a form.
- Backlinks DB: Link Gap takes your site and competitor sites and lists sites with observed links to the competitors and no observed link to you.
- Prospect Index searches stored pages by meaning as well as keyword, filtered by opportunity type: guest contribution pages, resource lists, expert roundups, podcasts, industry directories, award programs and speaking submissions.
- PageRank history reports monthly link-graph measurements for a host, its www variant and its domain, so a publisher's history is visible before you invest in the relationship.
For example, suppose a trade publication runs a piece naming your company alongside two competitors. Mention reports the mention and its reach. OppAlerts shows the page in Brand Mentions and checks for an observed link in Brand Unlinked Mentions. Site Info returns the publication's contact page and email. PageRank history shows changes in its link authority over several years. Use those details to decide whether to pitch the publication again.
How each is metered
Mention counts alerts and the mentions they return, so a noisy brand consumes the allowance faster than a quiet one tracking the same keywords.
OppAlerts counts calls: one tracked prompt or keyword, on one provider, on one day, with the days you want fresh data ticked per item. That counts what you asked for rather than what came back, so a busy news week does not change the figure.
OppAlerts also tracks AI answers on ChatGPT, Gemini and Google AI Mode and keyword positions on Google and Bing from that same allowance, which Mention does not sell.
Choosing between them
Choose Mention when social platforms and review sites are the sources that matter, when Boolean query control is central to how you filter, or when a large source count is the requirement.
Choose OppAlerts when the sources that matter are published pages rather than social platforms, and when what you do with a mention is check whether it linked and ask the publisher if it did not.
They overlap only on web mentions, so running both is a reasonable arrangement for a brand that needs social coverage and outreach research at the same time.
Use your monitoring terms and a typical follow-up task in the evaluation. Check that the service supports both finding the coverage and the work you intend to do next.
