How to limit Jetpack Open Graph description

  • I just ran into a use case where the Jetpack Open Graph functionality is causing trouble.

    A WordPress user asked me to see if the antispam plugin he activated to protect his email address on the Contact page was working. He was using Email Address Encoder, a plugin that scrambles email addresses.

    When I looked at the page source code, I noticed that the email address was included in plain text, inside the Jetpack Open Graph Tags (JOGT) description, easily available for spiders, which renders the obfuscation pretty useless.

    I looked for some ways to limit the output of the JOGT description field:

    – Using the Excerpt field: this works fine, JOGT uses the Excerpt rather than the post content. Alas, the Excerpt field is available for Posts, not for Pages. The contact page is obviously using the Page post type.
    – The “More” tag. This can be inserted even in a Page, but it’s not taken into account by Jetpack.

    What do you think, is there another way of controlling the output of the JOGT on Pages?

    Could Jetpack use the <!--more--> tag as a delimiter?

    PS: I know that there are ways of completely disabling the functionality, but the user wants to use the Publicize and Sharing modules — he just doesn’t want to give his email address in clear ??

    Thanks Adam for looking into it.

    I replicated the case on a test site, you can see it here:

    https://sandbox.4o4.ch/wp-git/contact/

    The content of the page is just that: 

    This is the contact page.
<!--more-->

Write to [email protected]

    I also found a workaround for the user, which is to activate excerpts for pages (of course there’s a plugin for that).

    But I think it makes sense for the Open Graph description to honor the <!--more--> tag, as the typical use — a teaser text for a longer article — is similar to what Open Graph is made for.

    I’m not sure I understand why this user has their email address in plaintext in the post in the first place. I would strongly suggest using Jetpack’s Contact Form module, which puts a handy form on the page and does not put the person’s email address anywhere in the source.

    As for why the email address is being pulled into the og:description tag, it’s because there has to be something there, after all. And since there’s no custom excerpt, Jetpack is just pulling in whatever content it sees from the page/post.

    But I think it makes sense for the Open Graph description to honor the more tag, as the typical use — a teaser text for a longer article — is similar to what Open Graph is made for.

    I can see an argument for this. I’ve filed an issue in our GitHub repo for it:

    Thanks for the feedback here!
