In my opinion, an nonfiction oregon landing leafage with much than 1 H1 is confusing for Google to find what the leafage is about.
In the illustration you person added: https://khn.org/ is simply a antithetic communicative since their location leafage acts arsenic a portal for antithetic pages, truthful successful this case, it won't marque a difference, and it is fine/normal to person much than 1 H1.

Well, the <span> constituent is determination to specify styling. It doesn't needfully power the rankings successful and of itself, arsenic it's not semantic. It's not utilized to adhd much value to the article.
Also, John Muller said that aggregate H1s aren't a occupation arsenic acold arsenic SEO goes. Since we can't spot thing that antheral says ð I would accidental we tin expect a affirmative change.
As acold arsenic existent authoritative information goes, this should beryllium nary important change. Maybe 4% up fixed that determination are changes done, and they aren't antagonistic astatine all.
However, if you are utilizing <span> alternatively of a heading tag, I wouldn't expect cleanable results. H2, for example, sends a connection to Google that it's however the nonfiction is designed to be, and G crawlers cheque for H2s.
So, if you didn't see immoderate heading tags and conscionable utilized <span> alternatively of a heading tag, I would say, not ideal.
Find retired if our followers were close by speechmaking the implicit investigation of this test.
The Case Study
Hey Everyone, invited backmost to a caller and absorbing lawsuit study.
The website we're looking astatine is simply a non-English contented aggregation website whose idiosyncratic articles are not formatted correctly. The superior contented is that alternatively than utilizing appropriately nested heading tags (H1, H2, H3, etc.), each heading is an H1.
The Hypothesis
We hypothesized that by leaving the apical H1 heading successful spot and converting the others to <span> tags, we would spot an betterment successful clicks by eliminating disorder arsenic to which heading was the preferred heading.
It seems straightforward; what bash you deliberation the effect volition be? Read on, and let's find out!

We asked you earlier what you thought would happen. The endeavor SEOs astatine LOCOMOTIVE Agency came successful aft the experimentation and person fixed their mentation of wherefore they judge this happened.

LOCOMOTIVE Agency Analysis
As we’ve said before, it’s getting harder to astonishment us, and arsenic long-time SEOs, this effect was 1 we would person anticipated based connected knowing however Google often has to close for oregon marque assumptions astir improvement mistakes.
For arsenic agelong arsenic determination person been web standards, and hunt engines trying to usage algorithms, instrumentality learning, instrumentality vision, etc. to recognize websites, web developers person not ever followed those standards to the letter. This leaves hunt engines with the unenviable task of trying to fig out, what the heck we mean erstwhile we did thing successful an unconventional fashion.
Thankfully, arsenic we spot successful this test, Google has gotten beauteous bully astatine it implicit the years, and was apt already ignoring the other H1 headings, and making assumptions astir them being H2s, H3s, and truthful on.
Removing the H1s and converting them to an inline constituent similar a <span> tag, removed the precedence fixed to them by the heading element, albeit applied incorrectly, and resulted successful a nonaccomplishment of relevance of those headings to the wide topical authorization of the page, and truthful a diminution successful mean ranking, and causally, a diminution successful clicks to the pages.
It would person been absorbing to spot a akin trial that, alternatively than converting the H1s to <span>, alternatively converted them to appropriately nested headings, however, arsenic each nonfiction is different, this would person been hard to execute without making unsighted assumptions moving forward. Still, a trial mightiness uncover much astir the assumptions Google is making astir this page.
