The Truth About Multiple H1 Tags in the HTML5 Era. Whether you're a webmaster or a web designer, there's a question you've most likely either asked or answered many times over the years.
That question is, "How many <h1>tags can I use per page, and how exactly should I implement them? " There are generally two reasons this question is asked.

If you are loading Google Fonts via a normal style sheet link in the <head>, then there’s no doubt that link is being looked at a render-blocking file. Any file that the browser needs to render the page, where it will not show the page without it, is known as part of the critical path. Normally, any CSS file is part of this critical rendering path.
Though Page Speed Insights is a good tool, remember that Google still uses what real users see as a metric for judging page speed and user experience. So what we want to do is improve our page speed for real users first, but also reduce the number of files on that critical rendering path. Optimizing the use of the Google Font API.

Although it isn’t a primary “signal” like the title tag or anchor text, keywords in your URLs can help with your Google rankings. But ONLY if Google can see the actual words in the URL.
