## Guides
- [Consumer Complaint Sites and How to Read Them](https://check-supplement-seller-reputation.pages.dev/consumer-complaint-sites/): Consumer complaint sites show how a seller handles problems, not whether a product works.
- [Reading a Business Profile With Care](https://check-supplement-seller-reputation.pages.dev/better-business-bureau-profile/): A better business bureau profile summarizes a company's listed details, its complaint history and how it answered them, but it is not a guarantee of product.
- [Looking Up Company Registration](https://check-supplement-seller-reputation.pages.dev/company-registration-lookup/): A company registration lookup tells you whether a business legally exists, under what name, and often where it is registered and who filed the paperwork.
- [Checking How Old a Website Is](https://check-supplement-seller-reputation.pages.dev/domain-age-whois-check/): A domain age whois check shows when a web address was first registered, which is a small clue about how long a site has existed.
- [Paid Reviews on Rating Sites](https://check-supplement-seller-reputation.pages.dev/trustpilot-paid-reviews/): Trustpilot paid reviews are a reminder that a star score on any rating site can be shaped by invitations, incentives or outright fakes.
