Website Launch Checklist: 12 Things to Do Before You Go Live

Launching a new website is exciting. After weeks (or months) of design, copy, and revisions, it's tempting to just flip the switch and send it live. But going live on a website that has broken links, no analytics, missing meta descriptions, or doesn't load on a phone is one of the most costly mistakes a small business can make. You only get one first impression with Google — and with every visitor who finds you.

Run through this checklist before you publish. Every single item here has a real cost if you skip it.

✅ 1. Test Everything on a Real Mobile Device

Don't just use the "mobile preview" in your website builder. Pull out an actual iPhone and an Android device and click through every page. Check that buttons are tappable, text is readable without zooming, images aren't cut off, and your navigation menu works. More than 60% of your visitors will arrive on a phone — your site needs to feel native to that experience, not like a shrunken desktop.

Also test on different browsers: Chrome, Safari, and Firefox. What looks perfect in one can break in another.

✅ 2. Check Every Link on the Site

Broken links are embarrassing, hurt your SEO, and make your business look careless. Before launch, click every internal link — every nav item, every button, every "learn more" — and confirm it goes where it should. Then check any external links you reference (review sites, partner pages, social profiles).

For larger sites, use a free tool like Dead Link Checker or the Broken Link Checker browser extension to automate this.

✅ 3. Set Up Google Analytics 4

If you're not measuring traffic from day one, you're flying blind. Google Analytics 4 (GA4) is free and takes about 15 minutes to set up. Create a GA4 property at analytics.google.com, grab your measurement ID (it starts with "G-"), and add it to every page of your site. Most website builders have a dedicated field for this in their settings — you don't need to touch any code.

Once it's live, you'll be able to see how many people visit, which pages they land on, how long they stay, where they're coming from, and which pages cause them to leave. This data becomes invaluable within the first 30 days.

✅ 4. Add Your Site to Google Search Console

Google Search Console (GSC) is separate from Analytics and equally important. It tells you how your site appears in Google search results — which keywords you rank for, how many impressions you get, whether Google has any crawl errors, and whether your pages are indexed properly.

Go to search.google.com/search-console, add your property, and verify ownership (the easiest method is the HTML tag or DNS record). This step also lets you submit your sitemap directly to Google, which accelerates indexing.

✅ 5. Submit Your XML Sitemap

A sitemap is a file that lists all the pages on your website so search engines can find and index them efficiently. Most website platforms (WordPress, Squarespace, Wix, Webflow) generate one automatically — usually accessible at yourdomain.com/sitemap.xml. Once you've verified your site in Google Search Console, go to the Sitemaps section and submit that URL. This tells Google "here's every page I want you to index."

✅ 6. Write Unique Meta Descriptions for Every Page

The meta description is the short summary that appears under your page title in Google search results. It doesn't directly affect your ranking, but it heavily affects whether someone clicks on your listing versus a competitor's. A generic or missing meta description means Google will pull random text from your page — which is rarely compelling.

Write a unique, 140–160 character description for every page. Focus on what the visitor gets and include a subtle call to action. For a service page: "Family-owned plumbing company serving Austin, TX. Emergency repairs, installations, and inspections. Call for a free estimate today."

✅ 7. Run a Page Speed Test

Slow sites lose visitors and rank lower on Google. Before launch, test your site at PageSpeed Insights. Aim for a mobile score above 70 (90+ is excellent). The tool will give you specific, actionable recommendations — the most common fixes are compressing images, removing unused JavaScript, and enabling caching.

"A one-second delay in page load time can reduce conversions by up to 7%. For a small business, that's real money walking out the door."

The most impactful single fix is almost always image compression. Make sure no image on your site is larger than 200–300KB. Use Squoosh or TinyPNG to compress images before uploading them.

✅ 8. Set Up Redirects from Old Pages

If you're replacing an existing website, any links pointing to your old pages — from Google, from other websites, from social media profiles — will land on a 404 error if those URLs no longer exist. That's wasted traffic and lost SEO equity.

Make a list of your old site's URLs and set up 301 redirects from each one to the closest equivalent page on your new site. Your web host's control panel, or plugins like Redirection (for WordPress), make this straightforward. At minimum, redirect your old homepage, service pages, and any pages with significant backlinks.

✅ 9. Test Your Contact Form

This one gets skipped more often than you'd believe. Fill out your own contact form and make sure the message actually arrives in your inbox. Check that the confirmation message the visitor sees is clear and professional. Confirm the notification email doesn't land in spam. If you have multiple forms (contact page, quote request, newsletter signup), test every single one.

A broken contact form can cost you weeks of missed leads before you notice it. Test it on launch day — and test it again a week later.

✅ 10. Confirm SSL Is Active (HTTPS)

Every website in 2024 should have SSL — that's what puts the "https" and the padlock icon in the browser address bar. Without it, browsers warn visitors that your site "is not secure," which instantly destroys trust and drives people away. Most reputable hosting providers include free SSL certificates via Let's Encrypt. Before you go live, type your URL into a browser and confirm the padlock appears and no security warnings show.

Also make sure your site redirects automatically from http:// to https:// — your hosting panel usually has a one-click option for this.

✅ 11. Proofread Every Page

Spelling errors and grammatical mistakes signal carelessness and erode trust faster than almost any design issue. Read every page out loud — it forces you to slow down and catch errors your eyes skip over. Then have someone else read it. Check proper nouns, phone numbers, email addresses, and your business address for accuracy.

Pay special attention to your homepage hero text and your services page — those are the pages most visitors actually read carefully.

✅ 12. Set Up (or Update) Your Google Business Profile

If you serve local customers, your Google Business Profile is arguably more important than your website for appearing in search results. It's what powers the map results and the local business panel in Google Search. Make sure your profile is claimed, verified, and fully filled out — business name, address, phone number, hours, website URL, category, photos, and a description.

Critically: your business name, address, and phone number on Google Business must exactly match what's on your website. Inconsistencies confuse Google and hurt your local rankings. If you're changing your website URL during this launch, update your Google Business Profile immediately.

Bonus: Add Social Sharing to Your Blog Posts

If your site includes a blog, add social sharing buttons to each post. They're easy to implement and meaningfully increase the chance a reader shares your content — which drives free traffic and builds backlinks. At minimum, include Twitter/X, LinkedIn, and Facebook sharing buttons.

Go Live With Confidence

A website launch isn't just a technical event — it's the start of your site's life as a marketing and sales tool. Every item on this checklist protects you from losing visitors, missing leads, and starting off with a Google penalty. Spend the extra few hours before launch. Your future customers (and your analytics dashboard) will thank you.
