Three years ago you paid for a new website, launched it, and moved on. Since then the services have changed, the team photos are out of date, the blog stopped in 2024, and leads have slowly thinned out. Now an agency is telling you it's time for another redesign. When business owners ask how often you should update your website, the standard answer is "redesign every two to three years." That answer is how sites end up in this exact spot.
A website isn't a project you finish and replace. It's a sales tool that needs small, steady updates to keep working. Sites that get attention every month rarely need a full rebuild, and sites that get ignored for three years always do.
This post lays out a practical update cadence: what to change monthly, what to review quarterly, what to audit yearly, and the specific signs that mean a full rebuild is the right call.
The short answer
You should update your website every month with new content and fixes, review its performance and conversion paths every quarter, audit all content every year, and rebuild it only when the platform, brand, or business has outgrown what updates can fix.
Key takeaways
The three-year redesign cycle treats a website like a car you trade in. You launch, you let it age, and you replace it when it looks dated. The problem is what happens in between: content goes stale, conversion paths break, speed slips, and the site produces fewer leads every month until the rebuild.
Buyers notice the decline. The Stanford Web Credibility Project, based on research with more than 4,500 people, lists "update your site's content often (at least show it's been reviewed recently)" among its ten guidelines for website credibility. A site that looks untouched tells visitors the business might be, too.
A steady cadence of small updates keeps the site credible and productive the whole time. It also means that when a rebuild does come, you're making it for a clear business reason rather than because the site fell apart.
Monthly updates keep the site current and give search engines a reason to keep crawling it. They don't need to be large. A business owner or marketing partner can usually handle them in a few hours.
Each month, add at least one piece of new content, such as a blog post, project spotlight, or updated FAQ. Add new reviews and recent project photos to the pages where buyers make decisions. Fix broken links and forms, apply platform and security updates, and update anything that changed in the business, like hours, staff, or service areas.
Quarterly reviews look at whether the site is still doing its job. This is where you catch problems that monthly upkeep misses. Three areas matter most.
Speed slips as images, scripts, and plugins pile up. Google's Core Web Vitals set clear targets: Largest Contentful Paint within 2.5 seconds, Interaction to Next Paint of 200 milliseconds or less, and Cumulative Layout Shift of 0.1 or less. Check these every quarter, especially on mobile. Our guide on how to speed up your website for better SEO covers the usual fixes.
Walk through the site as a buyer would and submit every form. Check that calls to action still match what you sell, that thank-you pages work, and that leads land in your CRM. Small breaks here cost real leads without anyone noticing.
Look at which pages bring traffic and leads, and which have dropped. A sudden dip often points to a technical issue you can fix quickly. If traffic has fallen off sharply, start with our checklist on why website traffic drops suddenly.
Working with a specialist
Keep your website producing leads every month.

How the Momentum Revenue Growth System works →Once a year, audit every page on the site. Decide whether each one should be kept as is, updated, merged with another page, or removed. Old posts with outdated stats or advice should be refreshed rather than left to drag down the rest of the site.
The yearly audit is also the time to check positioning. Ask whether the homepage still describes who you serve and why you're the right choice, and whether your service pages match what you want to sell next year. If the brand itself feels off, our post on signs your brand needs a refresh can help you decide.
"A website that gets a little better every month will outperform a website that gets rebuilt every three years. Every time."

Rebuild when updates can no longer fix the problem. That's a business decision, not a calendar one. These are the signs that a full rebuild is worth the investment.
If the issue is that the site gets traffic but not leads, start with targeted fixes before a rebuild. The ultimate guide to fixing a low-converting website covers what to try first. Based on TDG client experience, sites that follow a steady update cadence tend to last well past the three-year mark before they need a full rebuild.
The cadence stays the same across industries, but what you update changes. A custom home builder's monthly updates lean on new projects and buyer-education content, while a tree service company focuses on reviews, seasonal services, and storm response pages. For examples by vertical, see how custom home builders turn their site into a sales system and what a tree service website that converts looks like.
A website that keeps producing leads gets monthly content and fixes, quarterly performance reviews, a yearly audit, and a rebuild only when the business demands it - and building that ongoing improvement process is exactly where a specialist makes the difference.
