Choose Semrush when…
Broad keyword/competitor research, daily rank monitoring, Site Audit and AI-search visibility across the wider web are central.
SEO software comparison
Semrush vs Rank Math: which SEO tool is better?
Neither is a universal winner. Semrush is the stronger first choice for broader cloud SEO research, competitor intelligence, daily rank monitoring, Site Audit and AI-search visibility. Rank Math is the stronger first choice for WordPress-native on-page SEO, schema, sitemaps, redirections and site-level optimization. They are not one-for-one substitutes, and many WordPress teams may use both.
AlreadyChecked Verdict
Choose Semrush for broader cloud research and monitoring; choose Rank Math for WordPress-native implementation—or use both when the workflow needs both layers.
Semrush solves wider research, monitoring and audit work. Rank Math solves implementation work inside WordPress. Similar tracked-keyword counts do not make the products methodologically equivalent, and Rank Math's entry price should be judged against its higher renewal price.
Best for you if… you separate cloud research from WordPress implementation, compare introductory and renewal billing separately, and respect Rank Math's personal-site versus client-site license boundary.
| Choice | Best for | Current cost | Biggest advantage | Important limitation |
|---|---|---|---|---|
| Cloud SEO research Semrush SEO | Keyword and competitor research, daily rank monitoring, Site Audit and current AI-search visibility. | $139/month or $117.33/month equivalent when billed annually. | 5 monitored websites and 500 keywords tracked daily inside a broader cloud SEO workflow. | Its monitored-site and tracked-keyword units are not the same thing as Rank Math's WordPress license and Search Console-based analytics model. |
| WordPress implementation Rank Math | On-page SEO, schema, sitemaps, redirections, WordPress analytics and site-level implementation. | PRO €7.99/month equivalent billed annually, renewing at €8.99/month equivalent billed annually; Business €24.99 renewing at €27.99; Agency €54.99 renewing at €64.99. | PRO supports unlimited personal websites, while Business and Agency scale to client sites and larger keyword allowances. | Client websites are excluded from the PRO personal-site license; checked EUR pricing is not a universal currency; Rank Math's own analytics-cadence documentation currently conflicts. |

Current pricing: cloud platform versus WordPress plugin
| Option | Checked pricing | Current operating scope |
|---|---|---|
| Semrush SEO | $139/month or $117.33/month equivalent when billed annually | 5 monitored websites; 500 keywords tracked daily; broader cloud SEO/search workflow |
| Rank Math PRO | €7.99/month equivalent billed annually, exclusive of taxes; renews at €8.99/month equivalent billed annually + taxes | Unlimited personal websites owned 100% by the license holder; client sites excluded; 500-keyword tracking allowance |
| Rank Math Business | €24.99/month equivalent billed annually; renews at €27.99/month equivalent billed annually + taxes | 100 client websites; 10,000 tracked keywords |
| Rank Math Agency | €54.99/month equivalent billed annually; renews at €64.99/month equivalent billed annually + taxes | 500 client websites; 50,000 tracked keywords |
The checked Rank Math pricing surface displayed EUR, exclusive of taxes, and monthly equivalents billed annually. AlreadyChecked does not universalize that checked currency display to every buyer or call those figures month-to-month prices.
Introductory and renewal pricing are different
Rank Math's current checked pricing separates promoted annual-billed equivalents from higher renewal equivalents. For PRO, the checked surface shows €7.99/month equivalent billed annually and a renewal equivalent of €8.99/month. Business moves from €24.99 to €27.99; Agency from €54.99 to €64.99. Compare renewal basis, not only the entry headline.
PRO unlimited personal websites does not mean unlimited client sites
Rank Math says PRO can be used on unlimited personal websites that the license holder owns 100%. Client websites are excluded. Business and Agency are the client-site tiers. Ownership—not simply site count—controls that license boundary.
Both can show 500 tracked keywords, but the methods are not the same
Semrush currently lists 500 keywords tracked daily. Rank Math PRO lists a 500-keyword tracking allowance across connected websites. Rank Math says its Analytics / Rank Tracker data is pulled from connected Google Search Console and Google Analytics profiles via API. Similar numeric limits do not prove the same source, cadence or tracking methodology.
Rank Math's own analytics-cadence documentation conflicts
The current pricing FAQ says Analytics data updates every seven days for Free and every three days for PRO and Business/Agency. A separate Rank Math Analytics article says Free updates every three days and PRO updates daily. Those first-party surfaces conflict, so AlreadyChecked does not publish one paid Rank Math analytics cadence as settled.
The 15-day trial is Content AI—not a Rank Math PRO plugin trial
Rank Math offers a free plugin and a demo path for evaluating PRO functionality. Current paid-plan cards separately advertise a 15-day Content AI trial. AlreadyChecked does not relabel that as a 15-day Rank Math PRO plugin trial.
Refund, renewal and cancellation
Rank Math's current refund guidance says new Rank Math PRO / Content AI customers receive a 30-day money-back guarantee, while renewals are not refundable. Cancellation stops a future renewal while access continues through the current paid period.
Public affiliate program does not equal AlreadyChecked approval
Rank Math publicly advertises a 30% commission, a 60-day last-click cookie and a $200 minimum payout threshold. AlreadyChecked does not have a project-controlled Rank Math affiliate destination active for this page, so none is published here.
Which route fits your actual workflow?
Choose Rank Math when…
WordPress-native on-page SEO, schema, sitemaps, redirections and site-level optimization are the core job.
Use both when…
A WordPress workflow needs Semrush's broader research/monitoring plus Rank Math's implementation controls.
Important limitations
Tracked-keyword counts, site allowances, plugin features and update cadence are operating constraints—not proof that one product has universally better SEO data or outcomes. Checked currency and promotional pricing should not be generalized beyond the live purchase context.
