SEO: CTR harvest for /docs/comparison-networking

[philip638]

Page: /docs/comparison-networking

Before metrics (28d GSC): 781 impressions, 3 clicks, avg position 12.1 — page ranks but the snippet isn't converting.

What changed:

• Rewrote title + H1 to front-load the comparison query and state the concrete deliverable ("AI Agent Networking Compared" — feature-by-feature).
• Rewrote meta description (<=155 chars) to restate the searcher's problem (choosing between overlay networks) and promise the comparison.
• Added a 5-question FAQ block (Tailscale/ZeroTier replacement, NAT traversal, trust model, account requirement, libp2p diff) with FAQPage JSON-LD for AI Overviews eligibility.
• Added contextual internal links: from the vs-libp2p section out to the overlay-networks blog post, and a backlink into this page from the existing pilot-vs-tailscale-nebula-zerotier-ai-agents blog post (high-impression related post).
• Regenerated the plain-text twin (src/pages/plain/docs/comparison-networking.astro) to stay in sync per check:plain.
• URL/slug unchanged. No factual claims changed — this is a snippet/structure pass only, per the optimize playbook.

npm run build and npm run check:plain both pass locally.
