H1 missing in the template

Hello,
For good SEO, we have to follow heading tags like h1, h2, h3, h4 etc. Its is good practice to use page Heading tag always in H1; but when we use different kind of custom visual component then its hard for Robots which are looking for the page title because those look for H1 for page title where visual use different kind of h1 tags.

So what is the best solution for this for Google robot to find site page title without the html title. From html title thats not very much helpful.
