Here is the deal, I have an app that gets content via a webview of my website on the internet. The only thing am changing is that am setting a custom user-agent for this webview app, so I am able to target it.
Case 1: The regular website viewers with a browser will see the normal site.
Case 2: The users from the app will see the same website but with some changes in the page all on CSS and JS level, like changing styles, hiding elements, editing titles with js.
Will this affect my site SEO in any way? My thinking is no since the webpage is the same thing, and if search engine bots visit the page they will see the regular page, since they are not using the "custom user-agent" I created. Do search engines notice the changes made by JS? Are my thoughts valid? what do you guys think of this concept.
I know that's not how to do a proper, and friendly app, I am implementing this temporary, until I move the project to an actual native app, I just want to make sure it won't affect the site SEO in anyway.
