SEO Site Migration and Redirects in Google Sheets

Handling an SEO site migration or fixing 404 errors are critical tasks. They require a comprehensive redirect map to preserve search rankings and user experience.

Quick Checklist

Handling an SEO site migration or fixing 404 errors are critical tasks. Over 30% of URLs change during a typical site migration and each broken redirect risks losing hard-earned search rankings. A comprehensive redirect map is essential to preserve search rankings and user experience.

This guide walks you through using Flookup in Google Sheets for this process. It offers a powerful, cloud-based alternative to the traditional Excel Fuzzy Lookup method.

Mapping URLs for Site Migrations and 404s

Whether you are moving to a new domain or cleaning up broken links, you must accurately match old URLs to their new counterparts. An incorrect redirect map can lead to lost traffic and a poor user experience.

For years, SEOs have used the Fuzzy Lookup add-in for Excel, but this approach has its drawbacks.

Flookup Data Wrangler Versus Excel Fuzzy Lookup

The 80/20 Rule of Redirect Mapping says that 80% of a site's organic traffic flows through just 20% of its URLs. Prioritising these high-value pages in your redirect map catches the majority of traffic risk before it happens.

Why Flookup Is the Best Excel Fuzzy Lookup Alternative

Flookup's "Standardise Data" feature is designed for the complexities of modern SEO. It provides a full suite of tools to clean, normalise and prepare your URLs for a highly accurate fuzzy match, all without leaving Google Sheets.

Advanced URL Standardisation Tools

• Isolate URL Components for Better Matching:
  • Keep URL domain only: Simplify your URLs to their root domain.
  • Keep URL path only: Focus your matching efforts on the most important part of the URL.
• Deep Clean Your URL Slugs:
  • Remove punctuation marks: Get rid of special characters that can throw off a fuzzy match.
  • Remove unwanted words: Strip out generic words to focus on core keywords.
  • Remove diacritical marks: Standardise international URLs for consistent matching.

A Step-by-step Flookup Workflow for Your Redirect Map

1. Prepare Your Data: In a new Google Sheet, paste your old URLs into Column A e.g. from a site crawl or Google Search Console's 404 report and your new URLs into Column B.
2. Clean and Normalise URLs: To ensure the most accurate match, isolate the meaningful parts of your URLs. In Column C, use the `NORMALIZE` formula to extract just the path from the old URL. In Column D, do the same for the new URLs. This removes protocol and domain noise.
   =NORMALIZE(A2,,"path")
=NORMALIZE(B2,,"path")
3. Perform the Fuzzy Match: Now, match the cleaned old paths to the cleaned new paths. In Column E, enter the `FLOOKUP` formula. This formula looks for the value in C2 within the cleaned new paths (D2:D1000) and returns the best match with at least 80 per cent similarity.
   =FLOOKUP(C2, $D$2:$D$1000, 1, FALSE, 0.8)
4. Retrieve the Full New URL: The previous step gives you the matched *path*. To get the full, final URL for your redirect map, use a standard `VLOOKUP`. This finds the matched path from column E in your cleaned new path list (Column D) and returns the corresponding original full URL from Column B.
   =VLOOKUP(E2, D:B, 2, FALSE)
5. Review and Export: You now have your original old URLs in Column A and their best-matched new URLs in Column F. Manually review this list for accuracy. Once satisfied, you have a clean, two-column redirect map ready to be implemented in your .htaccess file or server configuration.
