Why does http security headers matter for crypto projects?

Why this check matters specifically for Web3

The HTTP Security Headers check is part of the Technical SEO module which Crawlux built specifically for Web3 brands.
What an audit failure looks like
When the HTTP Security Headers check fails on a live domain, the symptom usually shows up as one of three patterns: lower organic rankings for branded queries, lower AI citation rate from ChatGPT and Perplexity, or higher bounce rate from search traffic. The HTTP Security Headers check is mechanical to verify but mechanical to fix.
