@steveonz The link you provided doesn’t appear to be a tag page, but rather is a category archive. For example, the tag page for ‘office-365’ is located at the following URL: https://www.itopia.com.au/blog/tag/office-365/
We reviewed the source code for the ‘office-365’ tag page and did confirm that the robots meta tag is set to index as the following is output (see image here):
<meta name="robots" content="index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1" />
There are a number of ways you can set a page/post/taxonomy to noindex. We would recommend checking to make sure the robots meta tag is NOT set to noindex for the category archive in Yoast SEO, and you can check this setting by performing the following actions:
? In WordPress, go to Posts>Categories
? Click the ‘Edit’ link beneath the category you want to edit
? Scroll down to the Yoast metabox
? Click on the ‘Advanced’ area
? For ‘Allow search engines to show this Category in search results?’ make sure this is set to ‘Yes’
* Note (setting this value to Yes will set robots meta tag to index and setting No would set meta robots to noindex)
In addition, you can set categories to be indexed by performing the following actions:
? In WordPress go to SEO>Search Appearance>Taxonomies
? For Categories set ‘Show Categories in search results’ to ‘Yes’
? Click ‘Save Changes’
