To add keywords to an HTML page, you need to use the meta element with the attribute name=”keywords”. You can do this as follows:
<head>
<meta name=”keywords” content=”słowo kluczowe 1, słowo kluczowe 2, słowo kluczowe 3″>
</head>
In the above example, the value of the content attribute is a comma-separated list of keywords. You can use as many keywords as you want, but it is recommended that you use keywords that are related to the content of the page and help it be indexed by search engines.
It is also important not to overuse keywords or introduce unrelated keywords to improve your search engine rankings. Modern search engine algorithms are becoming more sophisticated and SEO tricks of this type can lead to a penalty for your site.
