Which one is for you
Pick DiagnoSEO if
- Fits if you run WordPress sites and want the DiagnoSEO Pro plugin with your SEO tools
- Works for freelancers running audits and keyword checks now and then on a small budget
Look elsewhere if
- Pricey if you need rank tracking or the API, as both start on Enterprise at $129 per user a month
- Tight if you're on Basic, as 60 credits a month is six keyword ideas reports at 10 credits each
- Watch out: extra credits are $1 per 10, need an active plan and expire after a year
- Watch out: monthly and annual plans list different limits, such as 100 projects monthly but 50 yearly on Pro
- Not for you if you want a free plan, as there's only a 7-day trial and refunds cover a first purchase within 7 days
Pick SE Ranking if
- Fits if you track lots of keywords daily across several client sites
- Works for small marketing teams who want research, audits and tracking under one login
Look elsewhere if
- Pricey if you're one person with one site, as Core is $103.20 a month even on yearly billing and there's no lower plan
- Tight if you need old data, since Core keeps 6 months of history and has 1 manager seat; extra seats start at $16 a month
- Pricey if you want white-label reports, as the Agency Pack is $69 a month extra and sold on yearly billing only
- Watch out: deeper AI search tracking is an add-on at $71.20 a month on yearly billing ($89 monthly)
- Watch out: payments are non-refundable unless the service wasn't delivered as promised, and there's no desktop or phone app

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
