Does SEO need to be maintained?

Yes. A search results page is a ranked competition that re-runs every time someone searches. Google makes thousands of changes to its ranking systems every year, including several significant core updates. Your competitors add pages, earn reviews, and improve their sites without pause. Standing still in a moving race means falling behind by default.

Websites decay too. Links break as other sites reorganise. Plugins and platforms update and can slow pages down. Business details change: prices, services, areas covered, opening hours. Every page carrying stale information tells both Google and customers that the site isn't looked after.

The rise of AI search adds a new maintenance layer. Google's AI Overviews, ChatGPT, and Perplexity all favour current, accurate, well-structured content when choosing what to cite. A page that was never updated since 2023 is at a real disadvantage when an AI assistant is deciding which local business to recommend today.

Maintenance needs vary by a wide margin. A small local site in a quiet market might need a few hours a month. A large programmatic site in a competitive market needs systematic weekly monitoring. The mistake is assuming the answer is zero: we've never audited a site that had been ignored for a year and found nothing broken.

If you do only one thing: set up Google Search Console (it's free), and look at it monthly. Declines show up there long before they show up in your enquiries.
