How we grade them
| 2.0GPASEO Tester OnlineFair | 2.6GPASEOptimerGood | |
|---|---|---|
| Value for money | CPlus is €56 a month billed annually, €672 up front and excluding VAT. The category's middle is $40 and its dearer quarter starts at $69, so this is ordinary for what is a wide suite. | 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 | D7-day trial on every plan, and the listing does not say whether a card is needed. Nothing is free after that. | 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 | BCrawler, keywords, rank tracking, backlinks, AI writing and white-label reports cover the job. Limits are plan caps, such as 500 tracked keywords on Plus, not missing tools. | 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 store rating is on record. You set up projects, keywords and a Search Console link first. | 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 | CWeb only, with Google Search Console as the one integration listed. | 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. |
| Best for | an SEO suite for consultants | branded SEO audits for agencies |

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.
