# MyPreferredSources > A free, no-account tool that generates a copy-paste HTML button. The button deep-links a publisher's readers to Google's source-preferences tool (google.com/preferences/source?q=) so they can add the site as a "preferred source" — making its articles eligible for a "preferred" badge in Top Stories, AI Mode, and AI Overviews. Everything runs client-side; there is no backend, account, or fee. ## What it does - [Button generator](https://mypreferredsources.com/): Enter a website URL, style the button, and copy the HTML. Google's official JavaScript button (its recommended, auto-localized embed) comes first; then our deeplink styles — Google's official badge image, a co-branded custom button (your favicon + site name + a Google trust mark), a stacked App-Store-style badge, and a floating corner button. - Validates eligibility in the browser: preferred sources work at the domain/subdomain level only (paths and a leading "www." are stripped; IP addresses and localhost are rejected). ## Key facts - Price: Free. No account, no sign-up, no limits. - Affiliation: Independent. Not affiliated with, sponsored by, or endorsed by Google. - Eligibility: Domain- and subdomain-level sites only (e.g. example.com or news.example.com). Subdirectories like example.com/blog are not eligible. - Surfaces: A reader's source preference applies across Top Stories, AI Mode, and AI Overviews — one pick covers every surface. ## Sections - [How it works](https://mypreferredsources.com/#how-it-works) - [Why a preferred-source button](https://mypreferredsources.com/#why-button) - [Where you appear](https://mypreferredsources.com/#where) - [SEO & AI SEO](https://mypreferredsources.com/#seo) - [How readers pick you](https://mypreferredsources.com/#for-readers) - [FAQ](https://mypreferredsources.com/#faq)
