Model total cost before the trial ends

Headline prices omit the usage, seats, add-ons, and migration work that often decide the purchase.

Writesonic

The current annual-billing page lists Starter at $79/month, Basic at $199, and Growth at $399; monthly billing is higher and Enterprise is custom.

Cost risk

Before buying, model prompts, daily answers, articles, audited pages, agent runs, projects, and seats separately; annual discounts do not offset an undersized tier.

Semrush

As checked September 8, 2026, SEO Classic Pro is $139.95/month or $117.33/month on annual billing. Guru and Business are $208.33 and $416.66 per month on annual billing.

Cost risk

Before buying, list required projects, tracked keywords, historical data, users, and reporting add-ons.

When neither is right

Do not use a subscription to replace an undefined operating process.

If the team lacks a Search Console baseline, target queries, a content owner, and a weekly operating cadence, establish that process with free first-party data first. Either subscription would otherwise add underused software cost.
