These technical gaps effectively "hide" Diffblue Cover - AI Agent for Java unit test generation and management - Diffblue from modern search engines and AI agents.

Top 3 Blockers

!
JSON-LD Schema: Organization, Product, FAQ, Website
Add schema.org JSON-LD to describe your key entities (Organization, Product/Service, FAQPage, WebSite, Article when relevant). Structured data makes your meaning explicit and improves the chance of rich results and accurate AI citations. Validate markup with schema testing tools and keep the data consistent with the visible page content.
!
Dedicated Pricing/Product schema
Use Product and Offer schema (or a pricing page with structured data) to describe plans, prices, currency, availability, and key features. This reduces ambiguity for both search engines and AI assistants and can unlock richer search snippets. Keep pricing up to date and match schema values to the visible pricing table.
!
No dark patterns or content hidden with CSS
Avoid deceptive UX patterns such as hidden content, disguised ads, forced sign-ups, or pricing surprises. Transparency improves trust and reduces the chance your site is treated as low-quality by ranking systems and AI assistants. Keep key information visible and consistent across devices, including on mobile.

Top 3 Quick Wins

!
List in public LLM indexes (e.g., Huggingface database, Poe Profiles)
List your tools, datasets, docs, or brand pages on major AI/LLM discovery hubs where relevant (for example model/dataset repositories or app directories). These platforms add credibility signals (likes, forks, usage) and create additional crawlable references to your brand. Keep names, descriptions, and links consistent with your official website.
!
LLM-crawlable llms.txt
Create an llms.txt file to guide AI crawlers to your most important, high-quality pages (docs, pricing, about, key guides). Keep it short, well-structured, and focused on authoritative URLs you want cited. Treat it as a curated “AI sitemap” that improves discovery and reduces the risk of crawlers prioritizing low-value pages.
!
Language declared
Declare the page language using the HTML lang attribute, and use hreflang for true language/region variants. Clear language signals help crawlers index the right version and help AI return the correct language in answers. Confirm that each localized page has the correct language code and self-referencing hreflang.
