When you share a post with Google Plus, when you use the 'Add Link' feature or enter the URL of a post, the link will automatically link to the thumbnail, title, and address of that link, Views and links are created.
Sometimes, however, thumbnail images are applied properly,
I'm in a hurry, so let me know how to fix it.
First of all,
The reason for the problem
If you enter a link to Google Plus, you will get the title (usually the content of the H1 tag) from the web page of the URL according to the algorithm you set up in Google Plus. In this process, the theme, default settings, If you already have the information and write down 'Yoast SEO' 'Person', you will get an error that Google Plus recognizes that the title of the web page is two.
And all web pages basically have the property that later command overwrites the previous command, and because the content set in 'Yoast SEO' is overwritten after the title of the site that is generated first, Weird content like the title of the site (the name we set in 'Yoast SEO') is extracted as the title of the Google Plus preview card.
