Hlo Friends,
How many Heading - H1 tag should be in the Web Page?

There are 6 heading tags.- H1, H2, H3, H4, H5, H6. Your H1 tag should be at the top of the page content.

On a single webpage, you should ALWAYS only have one H1 tag. For lower level tags, you can have as many as you want, but remember to put them in descending order while not skipping a level. (H1, H2, H3, H4, H5, H6 in that order, not H1, H2 and then skip H3 to go to H4 right away).

Only 1 heading tag i.e. h1 is alowed

It should have only 1 H1 tag in your web page

H1 heading tags requires in content once!

And preferably your keyword is also in that H1.

It should have only 1 Heading  (H1 tag)  in your web page

There are 1 to 6 heading tags i.e H1, H2, H3, H4, H6, H6, but on a webpage h1 tag is 1 other heading will be mentioned in the remaining 5 tags accordingly.

There must be only one heading h1 tag in a webpage.
