AI-written website copy: does it cost you trust?

Key takeaways

AI-written copy costs trust when it is generic, unchecked or inaccurate, not because AI was used. Google says it rewards helpful content however it is produced, but warns against mass-produced content made to manipulate rankings. Use AI for drafts and structure, then add your own facts, examples and voice, and check every claim.

• Google judges content quality, not whether AI helped write it.
• Generic phrasing makes a business sound like everyone else.
• AI can invent facts; check every number and claim.
• Add first-hand examples and specifics that only you know.

Does Google penalise AI-written content?

No, not for being AI-written. Google's guidance on generative AI content says it focuses on the quality of content rather than how it is produced. Using automation to generate many pages mainly to manipulate rankings is a breach of its spam policies on scaled content abuse. Helpful, accurate, original content is acceptable whatever tools were used.

Why does generic AI copy hurt credibility?

Generic AI copy hurts credibility because it says what any business could say. Phrases like 'we pride ourselves on delivering exceptional results' carry no evidence. Readers increasingly recognise the patterns. Worse, AI tools can produce confident errors, such as wrong regulations or invented statistics, which damage trust when spotted.

• Tone of voice for your website: sound like a business

How do you use AI without losing trust?

Treat AI as a junior drafter, not an author.

• Give it your facts: services, areas, prices, process and real examples.
• Use it for structure and first drafts, not final copy.
• Rewrite in your voice and cut generic phrases.
• Check every fact, number and legal point against a source.
• Have a named expert review and sign off the page.

• Cite your sources: back up the numbers on your website
• Author bios on a business blog: show who wrote it

Should you disclose AI use?

For ordinary marketing copy reviewed by your team, disclosure is not generally required. Be transparent where readers would reasonably expect it, such as AI-generated images that look like real people or automated advice. Never present AI-generated reviews, testimonials or people as real; that is misleading and, for reviews, unlawful.

When is AI copy fine as it is?

It is rarely fine unedited for pages that sell. It can be acceptable for low-stakes text such as alt text drafts or meta description options, once checked. For service pages, about pages and advice, the value comes from what only you know, which AI cannot supply.

What does this look like in practice?

A pattern we see: a site's service pages were generated in an afternoon and read smoothly, but every page could belong to any competitor. Adding the firm's process, areas covered, typical timescales and two real examples per page turns them into content buyers believe.
