I add the metadata like this
import { Metadata } from "next";

export const metadata: Metadata = {
title: "ICHICHAIN - 一番鏈",
description: "一番鏈 | 區塊鏈去中心化抽獎平台 | 一番賞",
};

and buying a custom domain at vercel www.ichichain.com

but still can't search with ichichain

it seems not indexed by google

How long is that ago? And how "visible" is your website on the web? This may take quite some time, dependent on the popularity of your site.

this will take some time

be patient, days up to weeks

u can speed it up, ask ur friends to google for the website

and use chrome to directly go onto the site (chrome uses that data aswell)

also, connect your domain with google search console

and use google analytics

and btw, u need way more metadata than this. take a look at the docs https://nextjs.org/docs/app/api-reference/functions/generate-metadata#basic-fields

ok thanks

a few days after is fine noe

now
