Should I use Title, H1 tag, Browser title and Slogan all at the same time

I’m building websites with Rapidweaver since 8 years.
But my confusion about H1 tag, Browser title, Title and Slogan recently returned again.
Could somebody please explain the rules to me?

The Health check of RW tells me that my site is healthy.
H1 tag and browser titles of my site are the same at every page
At the General section I checked Title and Slogan but left the text field empty.
But while checking my site https://www.3dprintingnoob.news at Cobiro.com the message is that the site is having “multiple H1 tags”.

Could somebody explain the rules to me please.
Do H1 tag and browser title have to be the same?
And what is the role of the Title and Slogan in the General section of Rapidweaver.

Should I use Title, H1 tag, Browser title and Slogan all at the same time for my websites?

Thanks

A browser title is what appears at the top pf the browser tab, It can be used by search engines for display on the SERP(Search engine results page). It will not affect your ranking but may be used for display at the Search engines discretion (if they think it applies.

The heading tags (H1 - H6) are used to define HTML headings.
<h1> defines the most important heading. <h6> defines the least important heading.
These very much can impact your ranking with search engines.

It’s considered best practice Only use one H1 per page - this should represent the main heading/subject for the whole page. Technically you can have more than one H1 on a page if, for example, the page contains two very distinct subjects.

Also, do not skip heading levels - start with <h1>, then use <h2>, and so on. Don’t start with an H1 then have an H4 next.

It’s probably a poor practice to have every page have the same h1 or Title.

The slogan is nothing in the world of HTML and the internet. It’s a business term that RapidWeaver uses that doesn’t have any special meaning. Some Themes might make it a heading tag (h2 or h3).

I’ve never heard of Cobiro, but the reason you are getting flagged for two h1’s on the page is you have one that you have placed on the page with an HTML stack

My shared experiences while learning Fusion 360 and 3d printing

And the Theme you are using(multilux) has one coded up in the page header along with an h2. These are both empty probably because “At the General section I checked Title and Slogan but left the text field empty.”

Thanks for your help, but I still don’t understand exactly. Do I have to apply a Title on the “Settings > General” section (or else in the “override default settings” in the “general settings” section)? I also don’t understand what you mean by “the reason you are getting flagged for two h1’s on the page is you have one that you have placed on the page with an HTML stack
I’m sorry I’m a little bit embarrassed that I’m this slow-witted.

The Theme you have chosen (Like many of the themes) is probably using the “Title” as an h1. I’d guess (I don’t have that theme so I can’t say for sure) that the empty h2 the theme is probably putting the “Slogan” into it.
Since those are empty they are creating empty HTML h1 and h2 tags.

There is no way without editing the theme to remove the h1 and h2 tags that it is using.

So I’d get rid of the HTML stack that you have the h1 in or make it an h3 and use the h1 (and h2) the theme is providing.

As for having them different for every page (and I would definitely want them to be a page subject) then you would want to use the “Override Defaults” part of the page inspector.

Ah, now it’s becoming clear . Thanks very much for your quick and useful replies.
