Search engines prioritize fresh and relevant content, so by regularly updating your blog with new posts, you give search engines new content to index, increasing the likelihood of your website appearing in search results.

And by writing blog posts around your keywords and topics, especially using long-tail keywords relevant to your niche, helps search engines understand the focus of your website and rank it higher for related searches. 

Linking to your other pages, creates a well-connected internal structure which helps search engines index your site more effectively, whilst engaging posts can increase the time users spend with you (dwell time).
