I’m a self-taught web developer and just started freelancing,
I develop small websites for small businesses and blogging-interested people around me.
after finishing the website, I used to create a Gmail account for this website and submit it to the search console to get indexed by Google.
in my first days, the website would take an average of 2weeks-to-month to get fully indexed by Google,
and it’s really important to get your website indexed quickly as possible to keep up with the current going events/trends, especially if you are a blogging or search results based website.
during my repetitive work of creating websites, the important thing that I noticed was: if the signup page when creating the Gmail account was this style1 instead of this style2, the whole website would be indexed by Google in just a couple of hours(instead of 2weeks-to-month),
and I would also receive “recommended changes” emails from the search console.
I remember once got the style1 signup page by using another browser than the one I usually use(but it is not always the case),
so I think that there is some sort of “Gmail trust score” or something like that, that Google uses to treat/process you across Google services.
I posted this to let you know that something like this exists and it is not all about the website content(it took me a lot of time trying just improving the content)
also if you can share your thoughts about how can I get the style1 page, and if you already know about something like this.
