Change H1 and H2 Tags for SEO

Hi there,
please have a look here https://www.ads-software.com/support/topic/how-to-change-post-title-heading-tag/

Thanks for that link. On the post pages what do you change for the header, which is currently tagged as H1? There can only be one H1 per page.

Hi there,
you will need to open archive.php and replace all H1 occurrences.
Try installing the WP Editor plugin to enhance the default editor and then navigate to the /themes/olsenlight/ folder to find the file.

Sorry, one more question: if I make these changes with the WP Editor is there a need to make a child theme, etc.?

Hello there,
You are correct!
If you decide to proceed with this modification I would suggest you create a child theme, copy over the files you are editing and make the modifications there. This will allow your changes to survive future theme updates. If you directly edit the theme’s files, all changes will be lost once you update.

Have a look at this guide to learn more about child themes and how to create one
