SEO
Structured data has 2 problems
Structured data found (BreadcrumbList, Organization, WebPage and WebSite) but with 2 problems, for example “Organization: logo is not an absolute URL ("https://www.nitrobox.com/wp-content/uploads/2020/02/Log…”.

AI search readiness
No llms.txt
There is no https://www.nitrobox.com/llms.txt, a short Markdown guide to your key pages for AI tools (llmstxt.org). It is optional and few AI tools read it yet, so treat it as a cheap extra.
3 checks passed
AI answer engines may read the site
Your robots.txt lets the crawlers behind ChatGPT search, Claude and Perplexity read the site and cite it in answers.
Organization data: 4 of 6 facts
Your Organization JSON-LD gives name, url, logo and sameAs (social profiles); description and contact details would complete it.
Text is in the HTML
Your server sends the page's text in the HTML (576 words), so crawlers that don't run JavaScript still read it.
Other pages
1 link to non-canonical URLs
Your homepage links to 1 page by a URL that isn't its canonical one, for example https://www.nitrobox.com/integrations, whose canonical is https://www.nitrobox.com/platform/functions/integrations. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.
