I'm currently developing a website in wordpress, with just two pages, homepage and gallery. I'm using the plugin Polylang for multiple languages, and Yoast for SEO.
My homepage in my native language (Portuguese), has a SEO title that Google is showing correctly, however in the English version, Google is changing the title.
Example: Yoast : "Website Name | City" Google : "City - Website Name"
I've already tried updating the page to "Website Name | City, Location", and waited a few days to see if Google changed the SEO accordingly. When it did (I checked the cache:website.com method to see the last update date), it changed to "City, Location - Website Name".
Is Google changing the SEO title by itself using their algorithm? I looked around and saw that that maybe the case but I didn't really found a workaround.
