Your Product's Business Card: Public Profile Pages for Vibe Projects

Think first: the profile page is for visitors, not for you

Many vibe projects' public profile pages are casually copied from the “account settings” page: avatar, nickname, email, registration date all dumped on the page at once. Developers think “complete information is good,” but what visitors see is a business card that is both boring and unsafe. The real reader of a public profile page is not you, but a stranger clicking in for the first time: within ten seconds, they need to judge who this person is, what they have made, and whether they are worth following or contacting. Every design decision should be reasoned backward from that reader: which information helps them judge, which information is merely your internal data, and which information invites harassment when displayed. This guide is about making that “product business card”: how to layer fields, how to organize content, how to offer privacy switches, and how to handle harassment. Boundaries first: this guide covers only the display and privacy of the public profile page, not account security itself — login devices and session management, two-factor authentication, and account deletion and data erasure each already have their own guides on this site; nor does it cover team and organization pages, which belong to the team invitation and onboarding guide. The product “Banxia Kitchen” and the person “Shen Xia” in this article are fictional examples, used only to explain the method, not to point at any real product.

Fields in three layers: public, social, private

Step one is to sort every candidate field into three layers in a table, and settle all later arguments by checking that table. The public layer is visible to anyone who opens the page: avatar, nickname, a one-line bio, public works or content, and public achievements and stats. The social layer needs a small relationship before it shows: following and follower lists, like and favorite activity, groups joined — this kind of information can be public by default, but users need a one-click switch to hide it, because not everyone wants strangers tracing their social circle through a follow list. The private layer never goes on the profile page: email, phone number, real name, birthday, precise location, registration time, and last login time. Banxia Kitchen once displayed “registered in 2024” on profile pages, and users said it felt like publishing how long they had been online; removing it cost no functionality. After layering, set one rule: new fields default to the private layer, and a product manager must produce a reason why visitors need to see it before it can move up a layer. This default-tight rule is the most effective way to block “just put everything up there”; conversely, a product that defaults to fully public will have every later tightening read as “quietly changing the rules.”

A bio is not a self-introduction; it is the visitor's basis for judgment

The one-line bio is the most-read, cheapest-to-write, and easiest-to-ruin block on a profile page. Ruined bios come in three typical forms: résumé style (“ex-big-company engineer, now indie developer, likes coffee and open source”), after which visitors still do not know what this person is doing now; slogan style (“changing the world with passion”), which says nothing at all; and keyword-pile style (“AI | product | growth | going global | evangelism”), which reads like a tag cloud. A good bio follows a simple formula: one sentence covering “who I am + what I produce here + what visitors can get from me.” The fictional Shen Xia at Banxia Kitchen went through three drafts before settling: the first was “food lover who likes cooking,” the second was “home cook updating three home recipes a week,” and the third was “home recipes every Wednesday and Saturday, with shopping lists and failure notes included — beginners following along basically won't fail.” Why is the third better? It gives visitors a verifiable expectation: update frequency, content form, and target audience. Under the bio, three more things belong: a featured-works entrance (at most three items, not the full works list), recent activity (defaulting to the last week, folding anything older), and an explicit contact rule (“DMs open, but no business inquiries” beats saying nothing, because what visitors fear most is a message disappearing into silence).

Works, activity, achievements: choosing beats piling up

The second common profile-page disease is block piling: a works wall, an activity feed, a badge wall, stats, and a follow list spread across the whole page, leaving visitors scrolling three screens before finding anything important. The selection principle follows the visitor's decision order: the first screen holds only “who this person is + the three works most worth seeing,” the second screen holds “what they have been doing lately” (an activity summary), and the third screen and beyond hold achievements, stats, and social relationships. The standard for picking three works is not the three highest-liked items, but the three that best represent the person's current direction; Shen Xia's most-liked item at Banxia Kitchen was a viral dessert, but she now focuses on home cooking, so her featured works should be three home dishes, not the traffic-winning dessert pinned at the top. Achievements and stats need restraint: streaks like “120 days of consecutive updates” and totals like “number of works” can stay, but with context — “120 consecutive days” persuades more than a bare number, while an unverifiable, easily gamed number like “100,000 views” is better left off. Activity summaries should show public activity by default, while semi-public behavior like likes, favorites, and DM exchanges needs its own switch, defaulting to hidden, so users do not unknowingly spread their behavior trail in front of strangers.

Privacy switches belong next to the profile page, not buried in settings

The most common failure of privacy controls is not missing switches, but switches buried so deep that users cannot find them. Profile-page privacy switches should sit right beside the profile editing entrance, with a live visitor-view preview: change a switch, and the right side immediately shows “this is what strangers see now.” At minimum, five groups of switches are needed: whether the avatar and nickname can be found by off-site search; whether following and follower lists are public; whether activity and like records are public; whether stranger DMs are accepted, and whether DMs need a prior follow; and whether online status and recent activity time appear on the profile page. Each switch group must state its consequence, not just the words “public/private”: for example, “when off, your follow list is visible only to you, and visitors opening your profile will not see this section.” Banxia Kitchen once placed its “hide activity” switch only at the third level of settings, so when a user faced harassment and could not find the switch, they chose to delete their account outright — in extreme cases, how reachable a privacy switch is becomes the retention rate. One more bottom line: once a user sets a section to private, site search, recommendation feeds, and public APIs must withdraw it in sync. “Hidden on the profile page but still exposed on the search page” is a double standard.

Harassment and scraping: a public page must assume hostile visitors

Once a profile page is public, it must be assumed that ill-intentioned people will visit it. Harassment defenses need at least four things. First, block and report entrances in a prominent spot on the profile page: a blocked person stops seeing your activity updates, and reporting should take no more than two steps. Second, stranger DMs should land by default in a “requests” inbox rather than the main inbox, and the sender should not see read receipts until the request is accepted. Third, avatar and image uploads need basic handling beyond right-click saving — more importantly, strip EXIF data at upload so images do not leak shooting locations; standardize metadata removal for all uploads. Fourth, forbid enumerating users through profile pages: user IDs must not be sequential numbers, profile URLs must not reveal registration order, and search endpoints need rate limits, so nobody can script a sweep of every profile page on the site. Banxia Kitchen learned the enumeration lesson early: profile URLs were sequential numeric IDs, someone scripted through them in order, and within days every user's avatar and bio had been packaged up; after switching to random string IDs and rate-limiting public endpoints, that kind of scraping stopped. These measures sound like a security team's job, but for a one-person team, random IDs, rate limits, and block-and-report are all cheap — waiting until after an incident to add them is what is truly expensive.

Company versus creator profile pages: one template, two priorities

There is no universal best profile page, because visitors' judgment criteria change with the scenario, and at minimum two priorities must be designed for: company and creator. A company-scenario visitor is usually a customer, partner, or recruiter trying to confirm “is this company or person reliable”: the page's priority should be verifiable credentials — the types of clients served, the shape of projects delivered, contact methods and response rules — with personal color kept restrained, and update frequency mattering less. A creator-scenario visitor is usually a fan or potential reader trying to confirm “what is this person producing lately, and are they worth following”: the priority should be featured works and update rhythm, the bio should state frequency and content form, and the activity summary should stay fresh — a profile page untouched for over a month automatically downgrades itself in a visitor's mind. Shen Xia at Banxia Kitchen belongs to the creator scenario, so her first screen is three featured works plus update rhythm; for a studio account taking corporate orders, the first screen should instead be service scope, cooperation process, and contact methods. The same field-layering rules can produce pages that look different in the two scenarios — templates can be reused, but priorities must be re-ranked against the visitor's judgment criteria. Before drawing any interface, ask “who is the visitor, and what are they judging?” That question matters more than the interface itself.

Screenshotted, reposted, impersonated: going public means accepting partial loss of control

Once a profile page is public, some loss of control should be accepted at design time; the key is to prepare responses in advance rather than improvising after an incident. First, screenshots and reposts: public content is by principle shareable, and expecting technical measures to fully prevent screenshots is unrealistic. What can actually be done is making sure reposts still lead back to you — keep a stable contact method or home page address in your bio and featured works, rather than relying only on in-platform follow relationships. Second, impersonation: someone opens another account with your avatar and nickname, and visitors struggle to tell them apart. Countermeasures include a verifiable mark for the official account (such as a home page link bound to a domain, and a consistent nickname and avatar across platforms), a prominent note on the profile page stating “this is the only official account,” and a fast impersonation-report channel whose entrance is not buried in a third-level menu. Third, old information that will not die: a bio you changed or a work you deleted may already live in search engine caches or other people's screenshots, so “deleted from the profile page” does not mean “gone from the internet.” Before publishing, every line should pass the standard of “once public, it may exist permanently.” Shen Xia at Banxia Kitchen once had a casually written bio reposted to another platform, and after she changed it, the reposted version kept circulating — the lesson is not “don't go public,” but “run everything through the permanent standard before publishing.”

Migration when redesigning a profile page: old fields, new fields, user notice

Profile pages rarely get it right the first time, and mishandled migration during a redesign leaves existing users' data fractured. Migration needs three field categories handled differently. The first category is fields that stay: avatar, nickname, bio, featured works migrate as-is, with users not needing to refill them; the page structure may change, but content must not be lost. The second category is fields being tightened: previously public by default, now private by default — such as follow lists or activity records. A redesign must not quietly flip users' existing choices; the correct approach is a clear notice telling users “this section will change from public to visible only to you, and you can change it back from the profile editing entrance,” with a grace period, rather than flipping it on launch day. The third category is new fields: a new “contact rules” or “featured works” section should launch empty with fill-in guidance, never with system-generated placeholder copy pretending to be user content, and never auto-filled from an old, unrelated field. Banxia Kitchen once turned a “personal signature” field into a “contact rules” field, and the system automatically carried old signatures over, so users' signature lines appeared in the “do you accept business inquiries” slot, causing plenty of confusion. The acceptance test for migration is simple: after a redesign, logging in with an old account should make your profile page look “clearer,” not “unfamiliar.” Any migration that makes a user feel “I didn't write this” is a failed migration.

Pre-launch checklist: walk your own profile page as a stranger

Before a profile page launches, do a “stranger-view walkthrough”: log out, open your own profile page in an incognito window, and answer six questions. One: within ten seconds, can you say what this person does? Two: are the three works most worth seeing on the first screen? Three: does any private information appear (email, phone, real name, precise location, registration time)? Four: have semi-public items like follow lists and activity records all passed through the user's own explicit choice? Five: can the block and report entrances be found within three seconds? Six: sharing the page link to a social platform — are the generated title image and summary what you want others to see (many products fail here: the share card grabs a large avatar image or internal test copy by default)? If any question cannot be answered, do not ship. One last reminder: a profile page is not better for being richer. Its job is to build trust within ten seconds, not to display an entire life across three screens. Make the public layer sharp, guard the private layer firmly, and keep the switches within reach, and the business card passes; whether it brings follows and cooperation is the content's own business — the page's job is only not to hold it back.

A profile page is not one-off decoration: review it every quarter

Profile pages have one more easily overlooked property: they expire. The update frequency stated in the bio changes, the direction of featured works shifts, contact rules change, and if the profile page still shows what it said six months ago, everything it communicates is outdated information. Review it once a quarter, doing only four things. One: is the bio still accurate — have update frequency, content direction, or target audience changed, and if so, change them rather than keeping old promises. Two: are the featured works still the current direction — the work that best represented you three months ago may have been replaced by a better new piece, and the featured slot should follow, not keep hanging the historical like-count champion. Three: do the privacy switches still fit your situation — after changing jobs, moving cities, or starting to take business inquiries, the public scope and DM rules may all need adjusting, so walk through the switches one by one during review. Four: is the share card still right — reshare the link once and check whether the title image and summary are the latest versions, so social platforms are not caching a six-month-old image. The review takes fifteen minutes, but it decides whether the profile page is a “living business card” or an “expired résumé.” A business card's value is not in how beautifully it is printed, but in whether its information is true; an outdated profile page damages trust more than an empty one, because visitors contact you based on the promises written there.
