7 Mistakes Made When Redesigning Your Website (and How to Avoid Them)

Launching a new website is exciting. You're finally bringing to life the design you've had in mind for years. But many small business owners make serious mistakes in the process without realising it — traffic drops, the phone goes quiet, you disappear from Google. Most of these are mistakes you could easily prevent if you knew about them in advance.

Mistake 1: Forgetting 301 Redirects

Your old site had a page at 'services/google-advertising'. On the new site, that URL changed or disappeared entirely. Google still knows about that page and is sending visitors there. Without a redirect, everyone who lands on it sees an empty 'page not found' screen. Worse, all the Google authority that page built up over the years is thrown away. Chain redirects (A goes to B, B goes to C) are especially dangerous — research shows that a significant portion of organic traffic is lost at each hop. And with Google tending to crawl sites less frequently in 2025-2026, recovering from these losses after a redesign takes even longer.

Mistake 2: Deleting Valuable Content

Your designer said 'keep it clean' and you removed those old blog posts, product descriptions, or service sub-pages. But some of those pages may be regularly bringing visitors from Google, have collected backlinks, and be quietly working for you. By changing your content management system, you risk erasing all that accumulated value. If you genuinely need to remove a piece of content, don't leave it as a 404 — redirect it to the most relevant page you do have.

Mistake 3: Ignoring Page Speed

New theme, new animations, bigger images... These can all look great but stretch your page load time. Research shows that mobile pages taking more than 3 seconds to load lose more than half their visitors. It's also well-established that each additional second of delay costs several percentage points of conversion rate. As of 2025, only half of websites pass all three of Google's core performance metrics (LCP, INP, CLS) — a redesign can easily upset this balance. INP in particular — which measures how quickly your site responds to a click or tap — tends to worsen when new, heavy JavaScript is added.

Mistake 4: Leaving Mobile Design for Later

Three-quarters of internet traffic in Turkey comes from mobile phones, and that share keeps growing year on year. So perfecting your site for desktop while putting off mobile with 'we'll handle it later' is a serious mistake. Google also evaluates your site from mobile: no matter how polished your desktop version is, it's the mobile version that determines your ranking. Buttons that are hard to tap on small touchscreens, text that doesn't fit, or forced horizontal scrolling will lose you both visitors and Google.

Mistake 5: Vague or Missing CTAs

A CTA — call to action — is the answer to the question 'what do you want visitors to do right now?' Research shows the majority of small business websites have no CTA at all on the homepage. Vague phrases like 'learn more' or 'click here' don't get people moving. Concrete, action-oriented text like 'Get a Free Quote', 'Call Now', or 'Request a Demo' performs significantly better. Having multiple equally prominent CTAs also trips you up: visitors can't decide which one to click, so they click none.

Mistake 6: Losing Your Measurement Infrastructure

The new site is live and everything looks great — but the GA4 (Google Analytics) code wasn't moved over, or was set up incorrectly. Now you have no way of knowing how many people are visiting, which pages are working, or how many people are filling out forms. Research shows that the majority of GA4 setups suffer data loss due to misconfigured tracking events. Within 24-48 hours of launch, check that data is flowing into GA4, re-verify Google Search Console with your new site structure, and test that form submissions and phone clicks are being recorded.

Mistake 7: Going Live Without Adequate Testing

This is the most common and most insidious mistake of all. If a 'noindex' tag is accidentally left on the site, Google won't index any of your pages — and it can take days to notice. In the meantime, nobody can find you. On top of that, forms might not be working, the payment page might be throwing errors, or the SSL certificate might be missing. Choose a weekday morning for your launch so your team can respond if something goes wrong. You may see minor ranking fluctuations in the first few weeks after launch — that's normal. What matters is quickly checking whether you've accidentally blocked anything.

• Is the SSL certificate active and is HTTPS enforced?
• Have 301 redirects been set up for all old URLs?
• Is the noindex tag only on the test environment and removed from the live site?
• Is the GA4 code working and is data coming through?
• Have forms been tested and is data going to the right place?
• Have robots.txt and sitemap.xml been updated?
• Has the appearance been checked on different devices and browsers?
• If there's e-commerce, has the cart and payment flow been tested?
