necgroup.co.uk — AI Site Grade

Analysis

I have enough data now. Let me write the audit.

The homepage delivers only 54 words of visible text to AI crawlers — a JS-rendering shell — despite every major bot receiving a 200 status with no block.

Crawler Access

All eleven AI bots tested (GPTBot, ClaudeBot, PerplexityBot, Google-Extended, OAI-SearchBot, ChatGPT-User, Bytespider, Applebot-Extended, anthropic-ai, Perplexity-User) receive 200 status with identical 50,380-byte payloads from Cloudflare. No UA-based blocking exists. However, the homepage returns only 54 words of visible text — the rest is JS-rendered hero content ("leading the way in live events", "we bring live to life") that AI crawlers cannot parse. The robots.txt contains zero AI-bot directives and no llms.txt exists (404). The sitemap.xml lists 639 URLs and is accessible.

Cold-Knowledge Gap

A frontier LLM queried cold on "NEC Group Birmingham" knows the brand operates the NEC, ICC, and Resorts World Arena, cites the 1976 opening by the Queen, and mentions 1.5M annual visitors pre-pandemic. But it also recalls accessibility complaints, poor signage, and long queues — reputational signals absent from the site. The model knows nothing about the 2024-2025 transformation: the Blackstone ownership, the new CEO Paul Reeve (appointed January 2026), the AXS ticketing partnership, the Levy F&B deal, the bp pulse LIVE naming, or the glamping resort. The site's own newsroom covers all of this in depth, but the LLM's prior is 2-3 years stale.

Schema Posture

Zero JSON-LD schema exists on any page examined — homepage, venues, products, leadership, partnerships, or news articles. No Organization, Event, Place, FAQPage, NewsArticle, or BreadcrumbList markup. The site describes itself as "the UK's leading live events business" and "one of the world's top venue management companies" but provides no structured data to substantiate those claims to AI engines. Heading structure is inconsistent: the homepage has two H1 tags, and venue pages use H1 for each venue name in a list-like layout.

Content Architecture

The site's strongest content lives on deep pages — the partnerships page (3,178 words), leadership team (793 words), and news articles (500-900 words each with full quotes and dates). But the homepage is a thin JS shell that AI crawlers see as 54 words. The /about-us/ page timed out on plain GET. Individual venue pages (/our-venues/the-nec/) redirect to the venues listing page, meaning AI crawlers cannot access dedicated venue detail pages — they hit a single page with all five venues listed. The site uses http:// links to external venue sites (www.thenec.co.uk, www.theicc.co.uk) alongside https://, creating mixed-protocol signals.

External Signals

The site is hosted on Cloudflare (A records: 104.21.6.232, 172.67.135.113) with Microsoft 365 mail. The TXT record necgroup.azurewebsites.net suggests Azure hosting beneath Cloudflare. The brand is owned by Blackstone (confirmed in the leadership succession press release) — a material fact absent from the homepage and about pages. The newsroom is active and well-written (April 2024 through October 2025) but these articles carry no schema markup and are not surfaced via llms.txt or any AI-friendly content map. The careers site lives on a separate subdomain (careers.necgroup.co.uk).

Findings

1. Homepage renders as a thin JS shell with only 54 visible words for AI crawlers High

   The homepage returns a 200 status with a 50,380-byte payload, but only 54 words of visible text are present; the rest is JavaScript-rendered hero content that AI crawlers cannot parse.

   What to change: Implement server-side rendering or static HTML for critical homepage content so AI crawlers can index the full value proposition.

2. Zero JSON-LD schema on any examined page High

   No Organization, Event, Place, NewsArticle, or other structured data markup exists on the homepage, venue pages, leadership page, partnerships page, or news articles.

   What to change: Add JSON-LD schema for Organization, Event, Place, NewsArticle, and BreadcrumbList across all relevant pages.

3. LLM knowledge of NEC Group is 2-3 years stale, missing key transformations High

   A frontier LLM queried on 'NEC Group Birmingham' recalls pre-pandemic visitor numbers and accessibility complaints but knows nothing about Blackstone ownership, the new CEO, the AXS partnership, or the Levy F&B deal — all covered on the site's newsroom.

   What to change: Publish an llms.txt file and ensure key facts (ownership, leadership, recent partnerships) are surfaced in structured data and on the homepage.

4. Individual venue pages redirect to the venues listing page, blocking dedicated AI access High

   URLs like /our-venues/the-nec/ redirect to /our-venues/, preventing AI crawlers from indexing individual venue detail pages.

   What to change: Serve unique content on each venue page instead of redirecting to the listing page.

5. About Us page times out on plain GET request High

   The /about-us/ page failed to load with a read timeout, making it inaccessible to AI crawlers.

   What to change: Ensure the /about-us/ page loads reliably and within reasonable timeouts.

6. No llms.txt file published Medium

   The site returns a 404 for /llms.txt, missing an opportunity to guide AI crawlers to key content.

   What to change: Create an llms.txt file listing important pages and facts for AI crawlers.

7. Robots.txt contains no AI-bot directives Medium

   The robots.txt file has rules for three user agents but none for AI crawlers like GPTBot or ClaudeBot.

   What to change: Add explicit directives for AI crawlers to control access and signal important pages.

8. Site uses mixed http:// and https:// links to external venue sites Low

   Links to external venue sites like www.thenec.co.uk use http:// alongside https://, creating mixed-protocol signals.

   What to change: Update all external links to use https:// for consistency and security.

9. Homepage has two H1 tags Low

   The homepage contains two H1 elements, which can confuse crawlers about the page's primary topic.

   What to change: Ensure only one H1 tag per page.

10. News articles lack NewsArticle schema markup Medium

    Well-written news articles with dates and quotes have no structured data, reducing their visibility in AI-powered search features.

    What to change: Add NewsArticle schema to all press releases and news items.

11. Blackstone ownership not mentioned on homepage or about pages Medium

    The fact that the NEC Group is owned by Blackstone is a material detail absent from the homepage and about pages, though confirmed in a press release.

    What to change: Include ownership information in the homepage or about page content and in Organization schema.
