A step-by-step website redesign checklist for business owners: what to audit, map and test before, during and after launch so your Google rankings survive.
By Vitus Rodrigo · 2026-11-05
A new website should bring you more enquiries, not fewer. Yet it is a familiar story for many business owners in Mumbai and Thane: the new site looks far better, but a few weeks after launch, calls from Google dry up. Nothing is "broken", the pages load, but rankings have quietly slipped. This website redesign checklist walks you through what to do before, during and after a redesign so you keep the search traffic you have already earned.
You do not need to be technical to use it. You need to know which questions to ask your developer, and which steps must not be skipped.
Google ranks individual pages, not your brand. Each page that ranks has built up signals over time: its URL, its title and content, the links pointing to it from other sites, and how people interact with it. A redesign often changes all of these at once.
The usual culprits are:
/services/interior-design becomes /what-we-do/interiors, and the old address now shows a 404 error. Google and every backlink still point to the old one.Almost all of these are avoidable with planning. Here is how.
Before any work starts, save:
Export these to a spreadsheet and keep it. This is what you will compare against after launch.
Use a crawler such as Screaming Frog (the free version handles up to 500 URLs) to list every URL on your current site, along with its title, meta description, H1 and status code. Also download your existing XML sitemap.
Some of your traffic may come from pages you have forgotten about, like an old blog post or a PDF brochure.
From the baseline, mark the pages that bring in real traffic, rankings or backlinks. These pages must either keep their URL or get a careful redirect, and their content should be kept or improved, never cut down.
Tell your designer and developer up front that rankings must be protected. A good brief for a redesign includes the list of protected pages, the requirement for a redirect map, and the expectation that the new site will be at least as fast as the old one. If you are working with an agency for website development in Thane or anywhere else, ask them to explain their redesign SEO process before you sign.
The safest redirect is the one you never need. If a URL is clean and descriptive, keep it exactly as it is. Change URLs only when there is a clear benefit, such as fixing messy addresses like /page.php?id=27.
For every old URL that changes or is removed, decide where it should go. Put this in a simple two-column sheet:
| Old URL | New URL |
|---|---|
| /services/interior-design | /services/interiors |
| /about-us.html | /about |
| /blog/old-offer-2023 | /blog |
Rules to follow:
www, http and https, trailing slashes.Moving content is a chance to improve it, not shrink it. For each protected page, keep the main topic and keyword, keep useful sections such as FAQs, and add anything missing. Good design makes long content easy to read; it should not delete it.
Check that each new page has:
Most of your Indian visitors are likely on mobile, often on patchy 4G. Compress images into modern formats like WebP, lazy-load images below the fold, limit heavy animations and auto-playing video, and test on a mid-range Android phone, not just the latest iPhone on office Wi-Fi.
Block the staging site from Google with a password or a "noindex" tag. Then write "remove noindex" at the top of your launch checklist, in bold. It is one of the most damaging and most common launch mistakes.
On the day the new site goes live, go through this list:
robots.txt is not blocking important pages.Launch early in the week, not on a Friday evening, so the team is around to fix issues quickly.
Some movement in rankings is normal in the first few weeks while Google recrawls the site. What matters is spotting real problems early.
Week 1: Check Search Console daily for crawl errors and 404s. Any important old URL showing a 404 needs a redirect added. Crawl the new site yourself to catch broken internal links.
Weeks 2 to 4: Compare traffic and rankings for your protected pages against your baseline. If a specific page has dropped sharply, compare old and new versions: did the content, title or internal links change?
Weeks 4 to 8: Look at conversions, not just traffic. A redesign that keeps rankings but makes the enquiry form harder to find still costs you business. Review your form, call and WhatsApp numbers against the baseline.
Keep the redirect map permanently. Redirects should stay in place for the long term, since old links on other websites will keep sending visitors for years.
If your site has only a handful of pages and little search traffic, you can manage most of this checklist with your developer. If Google brings in a large share of your leads, or your site has hundreds of pages, products or blog posts, it is worth having someone experienced plan the migration. A good redesign also lets you build a structure that can grow with new pages later without another rebuild, which is what we aimed for with the Instronics corporate website.
