SEO parameters are functional elements of the page code that are not visible to users, but at the same time carry information for browsers and search engines. They are not required to be filled out, but help optimize the search for the necessary information on the site.
Page title
The h1 header is the regular page title that users see on the site. It should be as human-oriented as possible: be brief and reflect the main essence of the article, and not resemble a set of keywords. Recommendations for writing an h1 heading are given in a separate article;

The page title title is not directly displayed on the page, but can be seen when you hover your mouse over an open tab and when you bookmark the page. It is the title that in the vast majority of cases is displayed as a link to the page in search results and therefore should be composed in such a way as to attract maximum attention. And the title is the most “strong” element of a document, influencing its position in any search engine. We also have a separate article on how to write the correct title heading or make its construction automatic.

URL stands for Uniform Resource Locator. A URL is just an address that is issued to a unique resource on the Internet. In theory, every valid URL leads to a unique resource. Such resources can be an HTML page, a CSS file, an image, etc.

Meta description
The description meta tag (meta description, “description”) is intended to create a brief description of the html page. Its content can be used by search engines to form a snippet. This tag does not affect the appearance of the page, as it is service information. It is located in the <head> </head> html block of the page code.
The description meta tag can affect the site’s position in the search results of those search engines that take it into account (in particular, Google). In addition, visitors, while viewing the sickle, read descriptions of the proposed pages. It is the snippet, which is generated taking into account the information written in the description field, that helps the user make the final decision - or not to go to the site offered by the search engine.

Keywords are words (or a set of words) that describe the topic of a page and are used by search engines to ensure the exact match (relevance) of search results.
For a page, you need to list keywords that relate specifically to it, and not to the site as a whole. For example, if you have an online shoe store and you are working on the SEO parameters of the “Delivery” section, you do not need to include the keywords “buy shoes”, “cheap shoes in Kiev”, etc.: they do not relate to this topic pages. Fill in the field with keywords like “delivery conditions”, “free delivery”, “how to order delivery”. The length and number of keywords are at your discretion, but usually 10-15 words are optimal.
