When a website is small, most visitors probably arrive through the homepage and navigate from there. As the site grows and more pages get indexed or linked from elsewhere, a larger share of new visitors will land directly on an interior page that was never written with a first-time reader in mind. The page might jump straight into details, assume the visitor already knows what the site offers, or use shorthand that made sense internally but means nothing to an outsider.
A practical first step is to check which pages actually receive direct entry traffic. Most analytics tools show this, often labeled as landing pages or entry pages. Once you know which pages people are arriving on, visit each one as if you had never seen the site before and ask whether the first few lines tell you what this page is, what the site as a whole does, and where you could go next if this page is not what you expected. If the answer to any of those is unclear, that page is a candidate for a short orientation block.
An orientation block does not need to be long. One or two sentences at the top of the page stating what the page covers and how it relates to the broader service or product is usually enough. The goal is not to repeat the homepage pitch but to give a newcomer a quick sense of context so they can decide whether to stay, explore further, or leave without feeling lost.
As the site continues to grow, this becomes an ongoing task rather than a one-time fix. New pages will keep appearing, and search behavior or referral sources may shift which pages get entry traffic over time. You can set a reminder to revisit your top landing pages periodically, or simply make it part of the process whenever you publish something new: before going live, read the opening lines from the perspective of someone who has no prior knowledge of the site and adjust anything that relies on context they would not have.
