How to Generate Canonical Tags at Scale to Avoid Duplicate Content Issues

Duplicate content can hurt your SEO — but manually setting canonical tags across hundreds of pages is a nightmare. With Summrly, you can generate correct, SEO-safe canonical tags at scale. Just enter your topic or site structure, and AI will identify duplicate or similar content and assign proper canonical URLs — ensuring Google knows which version to rank, not penalize.

Why a Content-First Website Solves This

Most sites accidentally create duplicates: filtered product pages, printer-friendly versions, or syndicated content. Summrly prevents SEO damage by starting with your content and using AI to map relationships between pages. It automatically suggests canonical tags that consolidate link equity and prevent indexing issues — making your site cleaner, stronger, and safer in Google’s eyes.

Step-by-Step Guide

Create Your First Topic – Enter your main category (e.g., “running shoes”) to identify potential duplicates.
Set Up Your Content Focus – Choose your site type (blog, e-commerce, news) for accurate tagging logic.
Add Keywords – Include variations that might trigger duplication (e.g., “men’s running shoes,” “best runners for men”).
Brand Details – Add your domain structure for correct URL mapping.
Complete Setup – Export or implement AI-generated canonical tags across your site.

Enter your main topic below to generate canonical tags at scale — and protect your SEO from duplicate content issues.

Case Study: 200 Pages, 1 Fix, No More Indexing Errors

An e-commerce site had 200 product pages with duplicate content due to URL parameters (e.g., ?size=10&color=blue). Google was penalizing them for thin content. They used Summrly to analyze their structure and generate canonical tags pointing to the main product URL. After implementation, duplicate indexing dropped by 95%, crawl efficiency improved, and organic rankings for key products increased by an average of 12 positions.
