Is hreflang even necessary?

Question

Search Engine Optimization

Hello! There is an information site without sales, it is planned to support several languages. For example, RU, EN, SP.
The structure of the pages will not be identical, for the Russian version there may be pages about trees, and for other languages ​​there may be similar pages, but about bushes. Those. it is planned to adapt to user requests in a particular language.

The essence of the question in this case is whether a tag is needed.


As I understand it, it is needed not so much to indicate the language of the page, but to indicate alternative versions in different languages. Or if the pages are not the same, just remove the attribute - rel="alternate", and leave the href=" example.com/lang " hreflang="lang" attributes.

Thanks for the replies!
