Which one is for you
Pick Diib if

- Too light for agencies, with no team seats or white-label reports listed
- Watch out: the pricing page shows only a monthly Pro price, with no yearly option or trial terms
- Tight if you don't use Google Analytics, Maps, YouTube or Facebook, as its traffic figures come from those

- Not for you if you want to pay with PayPal or use a phone or desktop app, as it takes cards only and runs on the web
How we grade them
| 2.4GPADiibFair | 2.6GPASEOptimerGood | |
|---|---|---|
| Value for money | CPro is $29.99 a month, just over the line of this category's cheapest quarter, and it watches up to 30 websites. There's no yearly price on the page, and no team seats or white-label reports listed. | BDIY SEO is $21.75 a month on yearly billing ($29 monthly), right on the line of this category's cheapest quarter. The limits are tight for the money: 4 crawls of 1 site, 20 tracked keywords and 25 keyword searches. |
| Free plan and trial | BFree with no card: a site health scan and daily score, keyword and backlink analysis, industry benchmarks, a weekly email and Google Analytics sync. A small business owner could live on that; Pro adds the AI tools and multi-site monitoring. | CFree single-page audits from the Chrome extension with no account, limited per day, plus a 14-day trial with the plan's full features. Fine for checking pages, not for running your SEO. |
| Features | CHealth scans, keywords, backlinks, benchmarks, an AI Visibility Score and an assistant that answers from your data. The gaps the listing names: AI prompts are set per industry rather than by you, and it recommends without changing your site. | CPage audits, a site crawler, keyword and backlink research, rank tracking, an AI writer, white-label reports and a lead-capture audit form. Broad, but the listing shows the gaps: 4 crawls and 20 tracked keywords on DIY SEO. |
| Ease of use | CNo rating on record. It's written in plain English, but it leans on the accounts you connect, Google Analytics, Maps, YouTube and Facebook, before the numbers mean much. | BNo rating on record, but there's little to set up: paste a URL or click the extension and you get an audit with fixes in priority order. |
| Platforms and integrations | BWeb only, connected to Google Analytics, Google Maps, YouTube and Facebook. No API on record and no desktop or phone app. | BWeb plus a Chrome extension, with Zapier and webhooks on Lead Generation and an SEO Audit API as a paid add-on from $100 a month. 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.
