Module 4: Protect Your SEO

Redesigns kill traffic when nobody plans the migration. This module builds your Ranking Shield: the redirect map, everything worth preserving, the pre-launch QA, and the launch-day sequence.

The Ranking Shield

The Ranking Shield is your complete plan for protecting search traffic through the redesign: what to preserve, what to redirect, what to check before launch, and what to watch after. Here's why it exists: most traffic drops after redesigns aren't mysterious. They're caused by three things — URLs changed with no redirects (visitors and search engines hit 404s), page titles rewritten (rankings were tied to the old titles), and content thinned out (the words that ranked got "cleaned up" into nothing).

Start with the inventory. From Module 1's audit, list every URL that gets meaningful search traffic and every keyword you rank for. For each ranking page, record its current title tag, its meta description, and its word count. These are the assets the shield protects. The rule is simple: if it ranks, don't touch it without a plan. You can improve a ranking page — but you do it deliberately, keeping the title's core keywords and the content's depth, not by rewriting it from scratch because the new design "needed shorter copy."

The shield also covers what search engines see but visitors don't: your XML sitemap, your robots file, your analytics and search console verification. All of these must survive the move to the new site — lose your search console verification and you're flying blind on the rankings you're trying to protect. Traffic you earned over years can die in a day. The shield is what stands between them.

Most drops aren't mysterious

The three traffic killers

URLs changed, no redirects

Visitors and engines hit 404s.

Titles rewritten

Rankings were tied to the old titles.

Content thinned out

The words that ranked got “cleaned up” into nothing.

Build brief

List your top 10 ranking pages with their current title tags. Which pages rank for your money keywords? These are the assets your Ranking Shield must protect.

The redirect map

The redirect map is a spreadsheet with two columns: every old URL, and where it goes on the new site. Every old URL needs a row. No exceptions, no "we'll figure it out later." When the new site launches, each old URL gets a 301 redirect — a permanent redirect that tells search engines "this page moved here" and passes most of the ranking power to the new address.

Build it in three passes. Pass one: crawl your current site (free crawler tools list every URL) and paste all URLs into column A. Pass two: for each old URL, write its new destination in column B — the matching new page, or the closest parent page if the old page is being removed. Pass three: flag the Keep List pages and top-ranking pages — these get reviewed twice, because a wrong redirect on a money page is the most expensive typo in the project.

Rules for the map: redirect to the closest matching content, never to the homepage (search engines treat mass homepage redirects as soft 404s — they don't preserve rankings); keep the redirect chains to one hop (old → new, not old → middle → new); and test every redirect before launch, not after. The redirect map is a spreadsheet. It takes an afternoon. Skipping it costs months of lost traffic.

An afternoon's work

Passes

Crawl every URL, map each destination, flag the Keep List twice.

Hop per redirect

Old → new. Never old → middle → new.

Build brief

Start your redirect map: list 10 old URLs and their planned new destinations. For any page being removed, which parent page will receive its redirect — and why is that the closest match?

The launch checklist

Launch day is a sequence, not a moment. Run this checklist in order. Before launch: test every redirect in the map (click each old URL, confirm it lands correctly); verify title tags and meta descriptions survived on ranking pages; check the site on a real phone (not a simulator); submit every form yourself; test the checkout or booking flow end to end; confirm analytics and search console are installed and recording on the new site; check page speed on mobile — if the new design is slower than the old, fix it before launch.

Launch day: launch during low-traffic hours (early morning, mid-week for most businesses); publish the redirects the moment the new site goes live — not an hour later; submit the new sitemap to search console; then click through the top 20 pages yourself and confirm they load, look right, and the forms work. After launch: watch search console daily for crawl errors for two weeks; compare traffic week-over-week for a month; check that the Keep List pages held their rankings.

Keep the old site backed up and the old URLs documented for at least 90 days. If something breaks, you need the map to diagnose it. Launch checklists feel tedious. Traffic crashes feel worse. Run the list.

Phases, in order

Before launch, launch day, after launch — the checklist runs straight through.

Days of backups

Old site and URL docs kept — you need the map to diagnose.

Build brief

Who will run your launch checklist, and when is your low-traffic launch window? Write the launch-day sequence with names and times.

Sam's redesign deleted 40 old blog posts and redirected all of them to the homepage "to keep it simple." Two months later, search traffic is down 35%. What went wrong?

Your turn: Draft your Ranking Shield in one page: (1) top 10 ranking pages + titles to preserve, (2) redirect map status, (3) pre-launch QA owner, (4) 30-day monitoring plan.

Your next 24 hours

Crawl your current site and export every URL into a spreadsheet — column A of your redirect map. Record the title tags of your top 10 ranking pages.

Column A: Old URL | Column B: New destination | Column C: Notes

Rules: every old URL gets a row; redirect to closest matching content (never the homepage); one hop only; Keep List pages reviewed twice; all tested before launch.

LAUNCH CHECKLIST

☐ All redirects tested ☐ Titles/descriptions preserved ☐ Phone test passed ☐ Forms tested ☐ Analytics + search console live ☐ Mobile speed checked ☐ New sitemap submitted ☐ Old site backed up

Module 4 cheat sheet

The Ranking Shield: preserve, redirect, check, monitor.
If it ranks, don't touch it without a plan — keep titles and content depth.
Redirect map: every old URL gets a row, mapped to closest matching content.
301 = permanent, preserves ranking power. Homepage redirects = soft 404s.
Launch in low-traffic hours; redirects go live the same minute as the site.
Watch search console daily for two weeks; compare traffic for a month.
