BuzzSumo vs Semrush: pricing, what each one monitors, and which to buy

For finding which content performed, who shared it and which journalist to pitch, yes. BuzzSumo's index of articles and engagement data is the thing it does better than anyone, and its PR and Comms tier at $299 for five users bundles a journalist database that would cost far more as a standalone PR tool.

For everything to do with search, no, and it is not close. Semrush covers keyword research, rank tracking, site audits, backlinks, competitor traffic and now AI answer visibility, at a starting price below BuzzSumo's. They are complementary tools that a content team often buys together, which is why comparing them head to head usually produces a misleading answer.

Yes, but not on the SEO ladder people compare against BuzzSumo. Semrush sells media monitoring inside the AI PR Toolkit, the product formerly known as Prowly, and it starts on the Pro tier at $279 a month billed annually. The $149 Base tier includes the media database and pitching but no monitoring.

Separately, the SEO and AI Search plans added AI visibility tracking, which watches whether your brand appears in AI-generated answers for prompts you choose, 50 a day on Starter and 100 on Pro Plus. That is brand visibility inside AI tools, not brand mentions across the web, and the two are easy to confuse when they sit under the same login.

BuzzSumo starts higher and scales by seats: $199 a month for one user, $299 for five, $499 for ten and $999 for thirty, all billed yearly. Semrush starts at $139 a month, or $117.33 billed annually, and charges for additional users on top of the plan.

The honest comparison depends on team size. For one person, Semrush is cheaper at every tier. For a five-person team, BuzzSumo PR and Comms at $299 covers all five seats, while five Semrush seats cost the plan plus four extra-user fees. Total the seats you actually need before you compare the front-page numbers.

Partly, and only for a narrow definition of monitoring. BuzzSumo alerts fire on content that mentions your keyword, which covers articles and shared posts well. What they do not cover is the conversation: Reddit threads, forum posts, podcast episodes and review sites are not in the index, and those are usually where a problem starts before it reaches an article.

The meter matters too. BuzzSumo sells saved alerts rather than mention volume, and the entry plan includes two. A brand tracking itself, a couple of products and three competitors has run out of alerts before it has run out of budget.

If the team's job is producing and distributing content, Semrush at $139 to $199 covers keyword research, competitor analysis and the site work, and it is the better first purchase. Add BuzzSumo when content discovery and outreach become a regular workflow rather than an occasional task, because that is the point where its index earns $199 a month.

If the team also owns the brand inbox, neither tool covers it. A content stack plus a dedicated monitoring tool costs less than pushing either of these up a tier to approximate coverage they were not built for.

Because they have not been updated. Semrush sold Pro, Guru and Business for years, and a large number of comparison and review pages still describe that ladder. The current page is headed SEO and AI Search and sells SEO, Starter, Pro Plus and Advanced at $139, $199, $299 and $549 a month.

The same staleness affects BuzzSumo, where several pages still list a Basic plan that is no longer on buzzsumo.com. Check both vendor pricing pages in your own browser before you build a budget from any comparison, including this one.

Ask BuzzSumo how many saved alerts your plan includes and whether that number is per user or per account, because the alert count decides whether the plan does the monitoring job at all. Ask what happens to alert history when you downgrade.

Ask Semrush which product line the quote covers, since the SEO ladder and the AI PR Toolkit are separate purchases with separate seats, and confirm the per-user price on both. If media monitoring is part of the requirement, get the AI PR Toolkit Pro tier named explicitly, not just Semrush.
