Frequently asked questions

Schema Engine is a HubSpot app that automatically generates, validates, and applies Schema.org structured data markup to your HubSpot CMS pages. It uses AI to analyze the real content on each page, determine the appropriate schema types, and embed validated JSON-LD directly into your page's HTML head. No manual coding, no developer tickets, no ongoing maintenance.

Schema Engine is built for HubSpot users on Marketing Hub Professional or higher. It's designed for marketing managers, SEO specialists, and web teams who want structured data working across their site without adding technical overhead. You don't need to understand JSON-LD or Schema.org to use it.

Schema Engine is built by Blend, a global, accredited HubSpot partner. Blend is ISO 27001 accredited and has deep expertise in HubSpot CMS development, structured data, and search optimization.

Schema Engine adds JSON-LD structured data to the HTML head of your HubSpot pages. This markup is invisible to visitors but readable by search engines and AI systems. It tells these systems exactly what your page content represents, whether that's an article, a product, an FAQ section, an event, a local business, or something else entirely.

Schema Engine is available as a HubSpot app. You can install it directly from the install link and connect it to your HubSpot portal in minutes.

Schema Engine makes your pages and content more machine-readable, which can improve your eligibility for rich results in Google, including FAQ dropdowns, product details, event dates, and other enhanced listings that stand out and earn higher click-through rates. It does this by generating validated JSON-LD markup tailored to your content and applying it directly to your pages.

AI search engines like Google AI Overviews, ChatGPT search, and Perplexity rely on structured data to interpret content, verify facts, and determine source authority. Schema Engine ensures your pages have clear, up-to-date schema markup so these systems can accurately understand and surface your content. Without structured data, AI systems have to guess what your content means, and they may overlook it entirely.

Yes. AEO depends on clear, machine-readable data about your content. Schema Engine generates markup that explicitly tells AI systems what entities and relationships your pages contain, making your content more likely to be cited in AI-generated answers, summaries, and overviews. And because Schema Engine continuously monitors your pages, that markup stays accurate as your content evolves.

Schema Engine supports all major Schema.org types, including Organization, WebPage, Article, Product, FAQPage, LocalBusiness, Event, BreadcrumbList, HowTo, and more. You don't need to choose which types to use. The AI analyzes your page content and automatically selects the most appropriate types based on what the page actually represents.

No tool or technique can guarantee rankings. What Schema Engine does is ensure your pages have accurate, validated structured data that makes your content more understandable to search engines and AI systems. This improves your eligibility for rich results and strengthens how your content is interpreted across modern discovery channels.

Schema Engine follows a multi-step process. First, it visits your selected pages using a headless browser and reads the fully rendered content. It then cleans the HTML and sends the content to an AI service with custom prompting. The AI analyzes the content, determines the appropriate Schema.org types, and generates tailored JSON-LD markup. That markup is validated against Schema.org standards, checked for security, and then applied directly to your page's HTML head.

Most schema tools use static templates or manual field mapping. You choose a type, fill in the fields, and it outputs a fixed block of code. Schema Engine does something fundamentally different. It reads your actual page content in context and determines what schema types and properties are appropriate based on what the page really represents. The result is markup that reflects intent and content, not just a form you filled out.

Yes. Schema Engine uses AI models (Claude and OpenAI) with custom prompting to analyze page content and generate structured data. The AI doesn't just tag keywords. It interprets the overall purpose and structure of a page to produce contextually accurate schema.

Schema generation typically takes 30 to 120 seconds per page, depending on the complexity and length of the content. If you select multiple pages at once, they're added to a queue and processed in sequence, so larger batches will take longer to complete.

Schema Engine supports site pages and landing pages. You can choose to monitor one or both content types. Blog posts are not included, as HubSpot CMS already applies its own schema markup to blog content.

Schema Engine checks your selected pages regularly for content updates. When a page changes, a new schema is automatically generated, validated, and applied, keeping your structured data aligned with your live content at all times. There's no need to manually trigger regeneration.

No. Schema Engine only adds JSON-LD markup to the HTML head of your pages. Your visible page content, design, and layout remain completely unchanged.

Installation takes just a few minutes. Visit the install link, select your HubSpot account, review the requested permissions, and click "Connect app." You'll be redirected to the Schema Engine dashboard, and from there you can start configuring which pages to monitor.

Schema Engine requests two permissions: read and write access to CMS pages (to fetch content and apply schema markup) and read access to CMS settings (to understand your site structure). These are the minimum permissions required for the app to function.

After installation, go to the app settings within HubSpot. Select your included domains, choose your content types (pages, landing pages, or both), and then browse the paginated list of available pages. Check the boxes next to the pages you want Schema Engine to monitor, save your selection, and you're done.

Yes. In the app settings, you can enable or disable the schema regeneration schedule at any time. Disabling it pauses all monitoring and generation without removing previously applied schemas.

If you disconnect or uninstall Schema Engine, monitoring and schema generation will stop immediately. However, any schemas already applied to your pages will remain in place. You can remove them manually through HubSpot's page settings if you choose to, by editing the Head HTML section for each page.

Yes. In the Schema Engine settings, go to the Included Pages tab where you'll see last-generated timestamps for pages that have been processed. From there, you can open any page in the HubSpot content editor, then go to Settings > Advanced to review the schema in the "Head HTML" box.

Technically yes, but the whole point of Schema Engine is to handle schema generation for you. If you edit the markup manually and the page is still in your saved selection, your changes will be overwritten when the next regeneration runs. If you're seeing something in the generated schema that doesn't look right, reach out to our team and we'll help resolve it.

Schema Engine will detect existing schemas and leave them in place. However, we recommend removing any pre-existing schema before using Schema Engine to avoid conflicts, duplication, or validation issues between old and new markup.

No. Schema markup is added to your page's HTML head as a lightweight JSON-LD script block. It does not affect page rendering, load times, or user experience in any meaningful way.

Schema implementation is immediate. Once Schema Engine generates and applies markup, it's live on your page. Search engines typically re-crawl pages within days to weeks, at which point your structured data becomes eligible for rich results and enhanced listings. The timeline for visible SEO impact varies depending on your site's crawl frequency, domain authority, and content quality.

Absolutely. Answer Engine Optimization depends on clear, machine-readable data about your content. Schema markup explicitly tells AI systems what entities and relationships your content contains, making your pages more likely to be cited in AI-generated answers, summaries, and overviews. It's one of the most direct ways to improve your content's readiness for AI-driven discovery.

Structured data strengthens your eligibility for AI Overviews by giving Google's AI systems clear signals about what your content represents. While Google determines what appears in AI Overviews based on multiple factors, having accurate, up-to-date schema markup improves the likelihood that your content is correctly understood and considered.

Yes. Blend, the company behind Schema Engine, is ISO 27001 accredited. The app uses industry-standard encryption and security practices throughout. All generated schemas undergo security checks to screen for malicious content before being applied to your pages.

Schema Engine accesses only the HubSpot permissions necessary for it to function: CMS page content and CMS settings. It stores generated schemas and basic profile information. It does not access or store contact data, CRM records, or any other HubSpot data beyond what's needed for schema generation.

Page content is sent to AI services (Claude and/or OpenAI) for schema generation. This is the core of how the app works. No other data sharing with third parties occurs beyond what's necessary for the service to function.

Yes. The free plan includes two pages, so you can see the quality of the generated schema and how it works within your HubSpot portal before committing to a paid plan.

Schema Engine offers four tiers: Free, Starter, Growth, and Business. These are designed to scale with your needs. Whether you're applying schema to a handful of high-priority pages or rolling it out across your entire site, there's a plan that fits.

Yes. If you need schema generation at significant scale, we offer bespoke packages designed for high-volume HubSpot environments. Get in touch with our team to discuss your requirements.

Yes. You can change your plan as your needs evolve. Schema Engine is designed to scale with you.

First, check that the page is still included in your saved selection within the Schema Engine settings. Also confirm that the schema regeneration schedule is enabled. If both are in order and you're still not seeing updates, content changes may not have been detected yet. Schema Engine checks for changes at regular intervals.

It could be. If the error references a JSON-LD block in your page's Head HTML, you can review the generated markup in HubSpot's page settings under Settings > Advanced > Head HTML. If you had pre-existing schema on the page, there may be a conflict.

Yes. Schema Engine focuses specifically on structured data and doesn't conflict with other SEO tools you may be using for keyword research, rank tracking, or content optimization. It complements your existing SEO stack by handling the structured data layer automatically.

You can reach the Blend team through the Schema Engine dashboard or by contacting Blend directly. We're here to help with setup questions, troubleshooting, and anything else related to your structured data.

Blend is a HubSpot partner, and we built Schema Engine because HubSpot doesn't include structured data on site pages or landing pages out of the box. Adding schema manually in HubSpot is tricky and time-consuming. Schema Engine solves that by integrating directly with the HubSpot CMS to read page content, apply markup, and monitor for changes, all within the portal structure and content workflows you already use.

You can, but it's a manual process. You'd need to tag content for each page individually, generate the markup, validate it, paste it into your page's HTML, and repeat the process every time your content changes. Schema Engine automates all of that: generation, validation, application, and ongoing maintenance, across all your selected pages.

Manual schema creation by a developer is accurate but expensive and time-consuming. It also creates a maintenance burden. Every time content changes, someone needs to update the markup. Schema Engine eliminates that cycle by continuously monitoring your pages and regenerating schema automatically when content changes.

Most AI schema tools require you to paste in a URL or content, generate a one-time output, and then manually add it to your site. Schema Engine is different because it's integrated directly into HubSpot, applies schema automatically, and continuously monitors and updates it. It's not a one-time generator. It's an ongoing system.
