Core Platform Terms
Listing / Ad / Post
The fundamental unit of any classified platform. A listing (also called an ad or post) is the page where a seller describes an item or service, sets a price, uploads photos, and provides contact information. On Avito it's called "объявление," on Craigslist it's a "post," on OLX it's a "listing." The terms are interchangeable.
In practice: Your listing is a micro-landing page. Every element — headline, photos, description, price — affects whether a buyer contacts you or scrolls past.
Classified / Classifieds Site
A classified is a type of advertisement, and a classifieds site is a platform that hosts them. The C2C (consumer-to-consumer) modelis dominant: individuals sell to individuals. Some platforms also support B2C (business-to-consumer), where small businesses list alongside private sellers.

Marketplace vs. Classifieds
A marketplace (Amazon, eBay) handles the transaction — payment, shipping, returns. A classifieds site (Craigslist, Avito basic) connects buyer and seller but traditionally stays out of the transaction. The line is blurring: Avito now offers delivery and escrow, OLX has integrated payments in some markets.
Case: New user, first week selling electronics on OLX Poland. Problem: Listed 5 items expecting platform-managed shipping like on Allegro. Buyers messaged asking about meetup locations — user didn't understand why. Action: Learned the difference between marketplace (Allegro handles logistics) and classifieds (OLX connects parties). Switched to local meetups with cash payment. Result: Sold 4 out of 5 items within 10 days. Understood the C2C dynamic and adjusted expectations.
⚠️ Important: Don't confuse classifieds with marketplaces when setting your selling strategy. On a classifieds site, you handle communication, payment, and delivery yourself. If you expect Amazon-level buyer protection on Craigslist, you'll be disappointed — and potentially scammed.
Listing Management Terms
Bump / Raise / Republish
Bumping means pushing your listing back to the top of search results or category feeds. On Avito this is called "поднятие." Most platforms charge for this — it's one of their primary revenue streams. Free bumping is usually limited to once every few days.
In practice: Bumping works best during peak browsing hours (evenings and weekends). A $2-3 bump at 7pm gets more eyeballs than the same bump at 3am.
Boost / Promote / Highlight
Boosting goes beyond bumping. A boosted listing gets visual emphasis — larger thumbnails, colored borders, "TOP" badges, or placement in premium positions. On Avito, the tiers are "Поднятие," "Выделение," and "Турбо-продажа." On OLX, it's "Promote" with options like "Top Ad" and "Urgent."

In practice: Boosting is worth it for high-margin items (electronics, vehicles, real estate) where the promotion cost is a small percentage of the sale price. For a $15 item, spending $5 on a boost makes no economic sense.
Auto-Renewal / Auto-Republish
Some platforms let you set a listing to auto-renew when it expires. This keeps it active without manual intervention. On Avito, free listings auto-renew after 30 days. On Craigslist, you must manually renew every 7-45 days depending on the category.
Draft / Inactive Listing
A draft is an unpublished listing saved for later editing. An inactive listing is a published ad that has been paused or deactivated — either by the seller or by moderation. On Avito, you can deactivate and reactivate listings without losing views history.

Moderation and Trust Terms
Moderation / Review
Moderation is the process where the platform checks your listing before (pre-moderation) or after (post-moderation) it goes live. Automated moderation uses AI to scan for prohibited content, duplicate images, and policy violations. Manual moderation involves a human reviewer.
In practice: Avito's 2026 AI moderation approves most listings in under 60 seconds. But if the algorithm flags your ad, manual review can take 2-24 hours. Avoid trigger words like "replica," "copy," or brand names in categories where counterfeits are common.
Shadow Ban
A shadow ban means your listings appear to you but are hidden from other users. You won't receive any error message — everything looks normal on your end, but no one can find your ads. Platforms use shadow bans instead of outright bans because they slow down rule-breakers who would otherwise just create new accounts.
Related: Trust and Reputation on Bulletin Boards: Reviews, Verification, Ratings, and Secure Transactions
In practice: If your views suddenly drop to near-zero across all listings, you're likely shadow-banned. Common triggers: duplicate listings, keyword stuffing, posting from a flagged IP address, or using photos copied from the internet.
Verified Seller / Verified Account
A verified badge means the platform has confirmed the seller's identity through phone verification, ID submission, or linked payment accounts. On Avito, "Подтверждённый профиль" requires phone and optional passport verification. On Gumtree, verification is tied to profile completeness and response history.
In practice: Verified sellers get 15-30% more responses on average, according to Avito's own data. Buyers filter for verified sellers, especially in high-value categories like electronics and vehicles.
Trust Score / Reputation
A numerical or visual indicator of how reliable a seller is. Combines factors like: account age, number of completed transactions, buyer reviews, response time, and listing quality. Some platforms display it publicly; others use it internally for ranking.
⚠️ Important: A new account with zero transactions and no verificationwill struggle to sell high-value items. Build trust gradually: start with smaller items, respond quickly, and get positive reviews before listing expensive goods. On Avito, accounts with 10+ positive reviews sell items 2x faster than accounts with none.
Escrow / Safe Deal / Secure Transaction
Escrow is a payment model where the platform holds the buyer's money until the item is delivered and accepted. On Avito it's called "Безопасная сделка," on OLX it's "OLX Доставка." The platform acts as a neutral third party.
In practice: Escrow protects both sides but adds fees (typically 3-8% of the item price). For in-person meetups with cash, escrow isn't necessary. For shipped items or transactions with strangers in different cities, it's the safest option.
Search and Visibility Terms
Impressions / Views / Contacts
- Impressions — how many times your listing appeared in search results or feeds
- Views — how many times someone opened your full listing page
- Contacts — how many times someone messaged, called, or clicked "Show phone number"
The conversion funnel: Impressions → Views → Contacts → Deal. A healthy listing converts 5-15% of views into contacts.
Category / Subcategory
The taxonomy that organizes listings. Choosing the right category is critical — a phone listed under "Electronics > Phones" will rank; the same phone listed under "Other" will be invisible. Most platforms have 10-20 top-level categories with 50-200 subcategories.
Filters / Attributes / Structured Fields
Filters let buyers narrow results by price, location, condition, brand, color, and other parameters. Attributes (or structured fields) are the data points you fill in when creating a listing. Listings with all attributes filled rank higher and appear in more filter combinations.
In practice: On Avito, filling all available attributes increases impressions by up to 40%. If a buyer filters by "Brand: Samsung" and you left the brand field empty, your Samsung phone won't show up — even if "Samsung" appears in your headline.
Relevance / Ranking
Relevance is how the platform decides which listings to show first. Ranking algorithms consider: keyword match, listing freshness, attribute completeness, seller reputation, boost status, and user behavior signals (views, saves, contact rate).
Case: Experienced reseller, clothing category, Avito Moscow. Problem: New listings got fewer views than competitors selling identical items at higher prices. Action: Analyzed competitor listings and found they filled all 12 available attributes. Reseller was filling only 4 (title, price, photos, description). Added size, brand, material, color, condition, season, style, and gender. Result: Impressions increased 3x within 48 hours. The listings started appearing in 8 additional filter combinations.
Pricing and Transaction Terms
Firm / Fixed Price
The seller's price is non-negotiable. Often indicated by "firm" or "fixed" in the listing. On some platforms, there's a specific checkbox for this.
OBO / "Or Best Offer"
The seller will consider offers below the listed price. Common on Craigslist and Facebook Marketplace. On Avito, the equivalent is "Торг уместен."
Free / Giveaway
The item is listed at $0. Platforms handle free listings differently: Craigslist has a dedicated "free" section; Avito allows $0 listings but monitors them for bait-and-switch schemes.
Bundle / Lot
Multiple items sold together at a package price. Common in categories like clothing, books, and baby items. Some platforms allow bundling in a single listing; others require separate listings per item.
Prepayment / Deposit
A partial payment made before the item is shipped or the service is delivered. Prepayment scams are the #1 fraud type on classifieds. Never send full prepayment to an unverified seller without escrow protection.
⚠️ Important: According to Avito's own fraud reports, 70%+ of scam cases involve prepayment requests outside the platform's secure transaction system. If a seller insists on prepayment via bank transfer or crypto — especially before you've seen the item — treat it as a red flag.
Account and Profile Terms
Account Age
How long an account has been registered. Older accounts generally receive more trust from both the platform algorithm and buyers. A 3-year-old account with transaction history ranks higher than a 3-day-old account.
Multi-Accounting
Using multiple accounts on the same platform. Most classifieds prohibit this in their terms of service. Platforms detect multi-accounting through phone numbers, IP addresses, device fingerprints, and payment methods.
In practice: If you need to manage listings across different cities or product categories, some platforms (like Avito Pro) offer legitimate business tools instead of requiring multiple personal accounts.
Profile Completeness
The percentage of profile fields filled out: photo, name, bio, phone verification, email verification, linked social accounts. Higher completeness = higher visibility and trust.
Activity Score
An internal metric some platforms use to measure how engaged a seller is. Factors include: login frequency, response time to messages, listing update frequency, and transaction completion rate. Higher activity scores can lead to better ranking.

Communication Terms
Response Time
How quickly a seller replies to buyer inquiries. Most platforms track and display this. On Avito, sellers with "responds within an hour" badge get significantly more contacts. On Facebook Marketplace, "Very Responsive" badge appears for sellers who reply within 15 minutes.
Lowball / Lowballing
An offer far below the listed price — typically 50%+ less. Considered disrespectful on most platforms. Some sellers preemptively state "no lowballers" in their descriptions, though this can come across as aggressive.
Ghosting
When a buyer or seller stops responding mid-conversation without explanation. Common on classifieds because there's no obligation to complete a transaction. Reduce ghosting by confirming meetup details explicitly and getting a phone number for day-of coordination.
No-Show
When a buyer or seller agrees to meet but doesn't show up. The #2 annoyance on classifieds after scams. Mitigate by confirming 1-2 hours before the meetup and offering a narrow time window.
Fraud and Safety Terms
Scam / Fraud
Deliberate deception for financial gain. Common classified scams include: prepayment fraud (taking payment and disappearing), fake escrow sites, overpayment scams (sending a check for more than the price and asking for the difference back), and phishing links disguised as "secure payment" pages.
Phishing
Fake messages or websites designed to steal login credentials or payment information. On classifieds, phishing often comes as a link to a "payment confirmation page" or "delivery tracking" that mimics the platform's design.
Flagging / Reporting
The mechanism for users to report suspicious listings or accounts. Flagged listings get reviewed by moderation. On Craigslist, enough flags from users can automatically remove a listing. On Avito, flagging triggers manual review.
Blacklist / Ban
A permanent or temporary prohibition from using the platform. A ban can be account-level (all activity blocked) or listing-level (specific ad removed). Bans are triggered by: repeated policy violations, fraud reports, multi-accounting, or prohibited content.
Platform-Specific Terms
Avito Pro
Avito's business subscription for professional sellers. Includes analytics, batch listing management, CRM-like tools, and priority support. Available in tiers based on the number of active listings.
OLX Delivery
OLX's integrated shipping and escrow service. The buyer pays through OLX, the seller ships through a partner courier, and money is released after the buyer confirms receipt.
Craigslist CL Flag
Craigslist's community-based moderation system. Users can flag listings for miscategorization, spam, prohibited items, or overposting. Enough flags remove the listing automatically without admin intervention.
Facebook Marketplace Commerce Policy
Facebook's rules for what can and can't be sold on Marketplace. Notably stricter than other classifieds: no digital goods, no services, no animals in many regions, no weapons, and strict rules about health products.
