WordPress sites come in two kinds for this job: a site running WordPress software on your own hosting, and a site hosted on WordPress.com. The place you can paste code and the way you can publish a check file depend on which one you have. This guide starts with the tag NetShow gives you, then follows the path for your kind of site.
WordPress menu names mentioned here are WordPress's own as of September 2026 and may move. If you cannot find a menu, search WordPress help for “Custom HTML block” or “add code to footer”.
First, publish your agent. Then open that agent's Deploy page and its embed page. Under Paste this tag into your website, press Copy code. Copy the whole tag exactly as NetShow shows it; it includes your agent's address and must keep its attributes. The page says to put it just before the closing </body> tag on each page where you want the corner bubble.
A WordPress site on your own hosting
For the bubble on every page, use a plugin you already have that adds code to every page's footer, and paste the NetShow tag there. If you or your developer edit the theme's footer, put the tag just before </body> in a child theme. A child theme keeps that edit when the main theme updates. Publish the change, then open a page of your site to check that the tag is present. You need only one copy on each page.
For a single page, edit that page in the block editor and add a “Custom HTML” block as its last block. Paste the tag into that block and publish the page. WordPress removes script tags when the account lacks permission to publish unfiltered HTML; an author account cannot place the tag this way. On a multisite network, only the network's super admin has that permission by default. If your editor account loses the tag on save, ask an administrator to place it through the site's footer instead.
The tag alone does not activate replies. On NetShow's embed page, go to Add your website and verify it. Enter the site's full https:// origin under Website address, without a page path, and press Request this site. If visitors use both the plain and www. addresses, request each address that the tag will run on.
Open Verify ownership and activate chat for the pending address. NetShow shows an exact line of text and an exact address ending in /.well-known/netshow-origin.txt. WordPress does not create this file. In your host's file manager or over SFTP, create a .well-known folder in the site's top folder, the one containing wp-config.php. Put a plain text file named netshow-origin.txt inside it, with only the exact text NetShow shows. The leading dot in .well-known matters.
Open the full check-file address in a browser and make sure it displays that text directly, without redirecting. If a security or caching plugin blocks folders beginning with a dot, allow /.well-known/ through. Return to NetShow and press Verify and activate. NetShow checks that file before it lets the tag answer visitors. If you paste the tag before verification, the bubble tells visitors the door is closed. Keep the file in place while you use the site.
A site hosted on WordPress.com
WordPress.com keeps script tags only on plans that allow plugins and custom code. If your plan has that access, use its site-wide footer code option for the tag. Follow the same NetShow request and check-file steps only if your site also lets you publish the exact file at /.well-known/netshow-origin.txt. Confirm that the file opens at that address before pressing Verify and activate. Having a place to paste a tag by itself is not enough for verification.
On a WordPress.com plan without plugin and custom-code access, WordPress.com strips the script tag, and you cannot upload the required check file. Use a link or button instead: on the agent's Deploy page, copy its Hosted Share Link and point the link or button to your agent's own page. That path needs no code in WordPress and no website verification.
