Make your site ready for the new sitelinks search box
To: Webmaster of (ชื่อเว็บ),
Google systems have detected that your site may be eligible for the new sitelinks search box. With it, you can make it easier for your visitors to reach specific content on your site directly from Google Search. We want to help you set up your site to take advantage of the new search box.
Here’s how to make sure your site is ready:
1 Verify you’ve got a functioning site-specific search engine If you’ve got a Google Custom Search Engine, that works too.
2 Add the necessary markup to your site's homepage We recommend using schema.org/SearchAction markup with JSON-LD, but you can also use microdata.
3 Set up a preferred canonical URL for your homepage Make sure all other page versions point to the one you want (use the rel="canonical" link element)
ก็ทำตามขั้นตอนเลยครับ
