Semrush provides keyword and AI prompt tracking. OppAlerts focuses on publication and content research. Semrush provides technical SEO analysis and site auditing. OppAlerts provides prospect, coverage, contact, and content research. The next step in your investigation helps determine which you need.
Suppose a monthly report shows a competitor above your product. You might need to check a redirect on your website. Or you might need to understand why an industry guide recommends the competitor. Both start with the same visibility observation, but each needs different evidence.
OppAlerts publishes this comparison. The plan details come from research done in September 2026. Check the current plans, user allowances, and billing terms before you buy.
Compare the plans against your actual workload
The Semrush SEO, Starter, Pro+, and Advanced plans reviewed were $139, $199, $299, and $549 a month. They covered 5, 5, 15, and 40 monitored websites, and 500, 500, 1,500, and 5,000 daily tracked keywords. Starter added 50 daily prompts, Pro+ 100, and Advanced 200. SEO didn't include a prompt set.
The Prompt Tracking setup guide names ChatGPT Search, Google AI Mode, and Gemini. Custom tracking is separate from broader AI visibility research. That research includes reports for domains you haven't configured, with a reviewed allowance of 300 reports a day. MCP starts at Starter, while API data integration is listed at Advanced. Higher plans also add historical SEO data, deeper keyword analysis, and location or device reporting.
A daily prompt allowance covers the set you track. It doesn't give you that many new prompts every day. Its plans include 30, 10, or 3 active campaigns, with daily search and team limits. Price the full workload, including the users and locations you need, before deciding which costs less.
Investigate the technical problem
If your product page has a broken redirect, you need a crawler or audit to investigate it. Semrush provides Site Audit and AI-ready Site Audit. OppAlerts doesn't audit websites, as the site audit FAQ explains. You'll still need that technical capability alongside any publication research.
If you need to understand the industry guide, read its selection criteria. Perhaps it only covers products with a particular integration. That might explain why yours is missing. Or you might find that your product qualifies but hasn't been included in a comparison the publisher maintains.
OppAlerts campaign research includes AI recommendations. API and MCP access are read-only. It doesn't provide Semrush's depth of conventional keyword research.
Find out whether you have something to contribute
OppAlerts helps you inspect collected coverage and observed links, then search prospect pages by subject and opportunity type. You can find publications accepting a relevant case study even when you aren't starting from a competitor backlink. The Semrush pricing page reviewed didn't describe these tools in the same form. That page alone doesn't establish what the whole product can do.
Available website contact records can help you find a submission or correction route. Read the current instructions and work out what evidence the author needs before preparing an approach. Stored contacts aren't verified for deliverability. Monthly Domain and Host PageRank history can point to further checks, and unlinked-mention reports find references to investigate. Neither guarantees that you'll be included.
Both products also assess content. Semrush lists content optimization from Pro+. The OppAlerts Content Optimizer compares writing you supply with selected taxonomy categories. Try the recommendations against the same brief.
