Ignoring Checks

You may wish to ignore checks on individual files, there are two ways to do this (1) Through a special front-matter field called mdseo-ignore or (2) by placing the word mdseo-ignore-all in your markdown file.

With Front Matter

To ignore a check via front matter, supply the proper value(s) in the mdseo-ignore field in your front matter. For example, if you wanted to ignore the mdseo_dupe_title and mdseo_image checks in a particular markdown file, you would inject the following front matter:

---
mdseo-ignore: [dupe_title, image]
---

You can find these values by consulting the help of the appropriate cli command, for example mdseo_dupe_title -h says:

... Ignore with front matter `mdseo-ignore:[dupe_title]`

If you want to ignore all seo rules, you can also pass all like so:

---
mdseo-ignore: all
---

There is a generic function mdseo_chk_fm that checks the presence, min length and max length of a front matter field. You can ignore any checks conducted by this function by passing in the appropriate fields to mdseo-ignore. These are the fields that you can ignore:

description, slug, image, authors

For example, if you wanted to ingore all of these fields you could put the following in your front matter:

---
mdseo-ignore: [description,slug,image,authors]
---

With The Keyword mdseo-ignore-all

Some markdown files may not have front matter, or it may not be appropriate to add front matter to a file. In this case you can place the text mdseo-ignore-all anywhere in the file and all checks will be ignored, the most common way to add this keyword is with a markdown comment:

<-- mdseo-ignore-all -->
