The sentence that is doing no work
"All our sitters are fully vetted." Almost every babysitting site says it. Because almost every site says it, it carries no information, and a parent reads straight past it to the next tab.
That is a shame, because vetting is the entire reason a family pays a service rather than asking the sixteen-year-old next door. It is your product. Spending one line on it and nine paragraphs on how much you love children is the wrong way round.
What a parent is actually asking
Underneath the polite question about vetting are four specific ones.
Do you know this person is who they say they are. Has anyone who employed them before said they were good with children, and did you speak to that person or just read a letter. Has any formal background check been done, of the kind that applies where we live. Can they cope if a child chokes, falls or has a reaction.
Answer those four, in that order, and you have written the page.
Write the ladder, in order
Identity. Say that you confirm identity from documents in person, and that you confirm the address. One line.
References. Say how many, from what kind of setting, and that you take them up by phone rather than accepting a written letter at face value. A parent who has ever hired anyone knows the difference, and it is the single most convincing line on most vetting pages.
Background checking. Name the check accurately for where you operate. In England and Wales that conversation is about the Disclosure and Barring Service, with different levels of check and eligibility rules that depend on the role. Scotland runs the PVG scheme through Disclosure Scotland, and Northern Ireland uses AccessNI. Elsewhere, and in the United States in particular, checks are arranged at state or provider level and vary widely. Say what you do, say which country's regime you are describing, and treat the detail as orientation rather than legal advice. If you are unsure whether a particular level of check is available to you for the work your sitters do, take advice before you publish a claim about it.
First aid. Say that sitters hold paediatric first aid training, and when it was last renewed. Renewal dates are what separates a real statement from a decorative one.
Insurance. If the service carries public liability insurance, say so plainly. If sitters are self-employed and carry their own, say that instead. Do not blur the two.
What not to publish
This is where good intentions go wrong, so it is worth being blunt.
Do not publish images of certificates, and do not publish certificate or disclosure reference numbers. A disclosure certificate is personal data about your sitter, it can carry sensitive information, and putting it on a public page is a problem for them and for you.
Do not publish sitters' surnames, addresses or dates of birth. First name and photograph, with their written consent, is enough for a parent to feel they know who is coming.
Do not describe a check as a certification or a licence if it is not one. A background check is a disclosure of information at a point in time, not a qualification and not a guarantee of the future. Say that clearly. Parents trust a service that is precise about the limits of its own checks more than one that oversells them.
Do not name or photograph children, ever, without written consent from their parent, and think hard about whether you need it even then.
Say what happens after the check
Vetting is not a one-off event, and the sites that read best say so. A short paragraph covering ongoing practice does more for trust than another adjective.
What is your policy on renewing checks and first aid. What supervision or check-in happens on a booking. How does a parent raise a concern, who reads it, and what do you do with it. What is your safeguarding policy, written in ordinary language, and where can a parent read it. If you have a designated person for safeguarding matters, say so.
None of this needs to be long. It needs to exist, and it needs to sound like something you actually do rather than something you drafted for the website.
Where it goes on the site
Give vetting its own page, linked from the header, with a name a parent would use: How we check our sitters. Summarise it in three lines on the home page, immediately near the rate, because the two answer each other.
Where you publish sitter profiles, repeat the relevant facts on each profile as fields rather than as prose: first aid held, checks completed, areas, age groups. Fields do not go stale silently in the way that a paragraph does, and they tell you when a renewal is due.
Then put parent reviews next to the booking route. A stranger vouching for you does something no policy page can.
Where this sits
Vetting and first aid stated for every sitter, with sitter profiles held as records and a safeguarding page written in plain language, is the standard build for a babysitting service website, and the same care runs through the other childcare and family websites. What each package covers is on pricing. Regimes and terminology differ by country, so confirm the detail for where you operate before you publish it.
