| API access | The maker says users do not need their own AI account or API keys; the documentation references plugin REST routes rather than a separately documented public SaaS API. | An access token is required for the API, and the maker says to contact them to obtain one; API limits are subject to fair use. |
| Privacy | The privacy policy says it collects account details, submitted domains, usage data, and IP addresses, and states that it does not sell or share personal data with third parties. | The maker says imported log data is anonymized at collection and personal data from logs is not stored. |
| Product | DefiniteSEO combines a WordPress SEO plugin with online tools for site audits, AI visibility, backlinks, and AI writing. | Seolyzer is a hosted technical SEO platform for crawling sites, analyzing server logs, and combining those data with Google Search Console. |
| Support | Listed support ranges from community support on the free audit plan to email, priority email, or priority support on paid tiers. | The maker describes support as provided by senior SEOs and offers contact by chat and email. |

In their own words
DefiniteSEO
DefiniteSEO brings WordPress SEO tools together with an online audit service for examining site health, AI-search visibility, backlinks, and content. Audits cover technical and on-page SEO, content, links, security, performance, accessibility, and DNS, with fixes prioritized. Its AI-visibility tools check whether ChatGPT and Google AI Overviews cite a site and assess pages for readiness for AI search. The WordPress plugin can apply individual or bulk fixes, schedule automated changes, and reverse changes within 30 days. It works with Classic Editor, Gutenberg, Elementor, and WooCommerce, and can import settings from Yoast or Rank Math. The AI SEO Writer can publish to WordPress or provide content for another CMS. Free options include an unlimited-sites plugin and an audit plan for one project and 50 pages per month. Paid plans are listed from $4.99/mo (annual). The audit service is not a standalone classic rank-tracking or keyword-research suite.
