Reply To: Does Google know what my website is about? (for internal linking)

With Google’s advances in linguistic understanding (BERT, GPT-3, etc.), the crawler should be able to understand that your site is about construction and not, say, boating. I’m sure you have enough construction-specific terms in your content that the generic types of words listed will become clear through context.

Your anchor text does not need to be full sentences long – just your keyword or a phrase with your keyword in it will do.
