A canonical URL is a tag that tells search engines which version of a page should be treated as the authoritative one when duplicate or near-duplicate content exists across multiple URLs. Setting canonicals correctly prevents search engines from splitting ranking value across duplicate pages.
Example
The same page lives at /pricing and /pricing?utm_source=linkedin. A canonical tag pointing to /pricing tells Google to index only the clean version.

How to Write Copy AI Answer Engines Can Quote
A practical guide to writing website copy that ChatGPT, Perplexity and Google AI Overviews can extract, attribute to your brand and cite.
Start with clean technical SEO — fast load times, proper heading structure, mobile responsiveness — then build content around what your actual customers are searching for. Most sites over-invest in keywords and under-invest in structure. Google needs to crawl and understand your site before content quality even matters. Fix the technical foundation first, then focus content on answering real customer questions clearly.
Your website likely isn't ranking due to a combination of thin or irrelevant content, weak technical SEO, slow load speed, or a lack of quality backlinks pointing to your site. Run a technical audit first — broken links, missing metadata, and slow pages are common and fixable quickly. If technical health is solid, the issue is usually content: not enough pages targeting real search intent, or content too generic to compete with more specific pages.
