SEO4Ajax can be integrated on vercel by adding a new rule in the "rewrites" property of the vercel.json file. You just have to replace <token> with your site token on SEO4Ajax.
{
"rewrites": [
{
"source": "/:path(.*)",
"has": [
{
"type": "header",
"key": "user-agent",
"value": ".*google|bot|lighthouse|spider|pinterest|crawler|archiver|flipboardproxy|mediapartners|facebookexternalhit|insights|quora|whatsapp|slurp.*"
}
],
"destination": "https://api.seo4ajax.com/<token>/:path*"
}
]
}Warning: This configuration works for all application paths except the home page.
