Very often professionals involved in website promotion ask themselves what will happen if H1 matches TITLE. Let's define these concepts. Title is the name of the web page, it is visible in the browser and plays a role in the ranking of the website, allowing you to determine the relevance of the web document in relation to a particular request. In order to use this tool rationally, it is important to adhere to the rule that its length should not exceed 65 characters, it must contain a key, and there should be no water in it. On the other hand, H1 represents the title of the page itself. Users see it, and it is it that indicates the content of the document itself. There are no rules for writing H1, but it is logical to assume that it should have fewer characters than the title. At the same time, there are no clearly formulated conditions on the part of search engines, so in fact H1 may well duplicate Title. Although this is not rational. Yes, by itself, this circumstance will not lead to the website being sanctioned, but if there are other violations, it can increase the likelihood of applying a filter to the website. Therefore, it is completely logical to assume that Title and H1 should overlap with each other and have a single semantic load. In this case, you just need to take into account the fact that the first is intended for the search engine, and the second for the website visitor and output to the SERP snippet.
