Why have a blog on a company website?

It brings organic (free) traffic for specific questions and topics your main service pages naturally don't cover in enough depth — for example, a "website development" page can't explain in detail "how long it takes" or "what a CMS is", but a separate blog article on each of those topics can, and each such article is a new ranking opportunity.

It builds trust and the perception of expertise — when a potential customer finds your detailed, useful article on a topic they care about, before they even call, they already form the opinion that you understand their problem better than the competition.

It gives concrete, ready material for sharing on social media — instead of inventing a new post from scratch every time, you share a link to an already-written, detailed article.

Start from the questions customers most often ask you by phone, email or in person before deciding to hire you — those are your first, most valuable topics, because you already have real-life confirmation they are sought-after and relevant.

You don't have to publish daily — a few quality, in-depth articles per month bring more long-term value than daily short, shallow posts nobody finds on Google.
