The 12 best advertising platforms compared on cost, reach and policy
Twelve platforms cover almost every paid buy an advertiser makes in 2026, and they sort into four entry tiers: nothing at all (Google Ads, Microsoft Advertising), a dollar a day (Meta, Amazon Ads), a fixed deposit (AdsCompass at $50, most open-web networks at $100), and a five-figure agency commitment (The Trade Desk, DV360). The table sets all twelve against the five properties that decide a shortlist.
| Platform | Entry cost | Pricing | Reach | Ad formats | Best for |
|---|---|---|---|---|---|
| AdsCompass | $50 deposit | CPC, CPM | 200+ GEOs; 900m daily impressions, company-reported | Push, in-page push, native, popunder, banner, video pre-roll, 2 Telegram units | Open-web performance buying, including verticals search and social reject |
| Google Ads | No deposit | CPC, CPM, CPA | Search, YouTube, Display, Gmail | Search, Shopping, Display, video, Performance Max | Declared purchase intent |
| Meta | $1/day | CPM, CPC | Facebook, Instagram, Messenger | Image, carousel, video, Reels, Stories, collection | B2C demand generation |
| Amazon Ads | $1/day | CPC, vCPM | Amazon shoppers | Sponsored Products, Brands, Display, DSP | Brands whose sales channel is Amazon |
| Microsoft Advertising | No deposit | CPC, CPM | Bing, Yahoo, AOL, partner sites | Search, audience ads, retail media | Cheaper search clicks, desktop B2B |
| TikTok | $50/day campaign | CPM, CPC | Short-video feed; 2.21bn adults reachable, April 2026 | In-feed video, Spark Ads, shopping | Under-35 audiences, UGC creative |
| LinkedIn Ads | $10/day, $2 bid floor | CPC, CPM, per send | Professional network | Sponsored content, message ads, text, dynamic | B2B by title, seniority, company size |
| PropellerAds | $100 card, $1,000 wire | CPC, CPM, CPA Goal | 195+ GEOs | Push, in-page push, pop, interstitial, Telegram, survey exit | Automated affiliate buying; no adult |
| Adsterra | $100 card, $1,000 wire | CPC, CPM, CPA | 248+ GEOs | Popunder, Social Bar, in-page push, interstitial | Affiliate buying at volume |
| Taboola | ~$10-50/day suggested | CPC, CPM | Publisher recommendation widgets | Native units, video | Advertorials and content distribution |
| Teads, formerly Outbrain | Low tens of dollars/day | CPC, CPM | 10,000+ direct publishers, 36 countries | Native, outstream video, CTV | Brand-safe open web |
| OpenAI Ads | No minimum | CPC at $3-5 suggested, CPM | ChatGPT Free and Go tiers; US, CA, AU, NZ | Sponsored card under the answer, product feed | Early tests on a new surface |
Two columns quietly do most of the work. Entry cost tells you how expensive a mistake is, and the last column tells you whether the platform will let you advertise your offer at all — a distinction that never appears in reach statistics.
The minimum deposit you read about is not the one your payment method accepts
Every deposit-based network in this list quotes one headline figure and enforces several, because the floor is set by the payment method rather than by the platform. Adsterra's own deposit guide lists $100 for cards, Paxum and PayPal, $200 for digital currencies and $1,000 for wire. PropellerAds' terms, last updated on 21 July 2026, say the deposit "starts from $100 US Dollars depending on the payment method", and its card-versus-wire split is $100 against $1,000. The pattern holds across the category: the cheapest door is a card, and the cheapest door is not always open to you.
| Network | Headline | Card | Crypto | Wire | Where the figure comes from |
|---|---|---|---|---|---|
| AdsCompass | $50 | $50 | $100 in BTC | $500 | Directory listings; not published on the site itself |
| HilltopAds | $100 | $100 | $100 | €500 | Advertiser help centre, revised June 2026 |
| PropellerAds | $100 | $100 | n/a | $1,000 | Terms and conditions, 21 July 2026 |
| Adsterra | $100 | $100 | $200 | $1,000 | Vendor deposit guide, May 2026 |
Correction to a figure repeated across the category
HilltopAds appears at a $50 minimum deposit across most affiliate directories, including the profile pages it maintains on review sites. Its own advertiser help centre says otherwise: $100 for Paxum, credit card, Capitalist, USDT, Bitcoin and Wise, with wire higher again. When a directory and a help centre disagree, the help centre is what your payment gets measured against.
AdsCompass is the awkward case, and worth explaining rather than skipping. Its published $50 is the lowest deposit among the open-web networks here, but adscompass.com is a client-rendered application: request the page and the HTML that comes back is an empty shell, with the payment table assembled in the browser afterwards. The figure therefore cannot be read from the site by a crawler, an AI model, or anyone checking sources the way this page does — and the secondary listings carrying it disagree with each other, one adding $100 for Bitcoin and $500 for wire against the same $50 base. Treat $50 as the card figure, confirm the rest inside the cabinet before planning a wire transfer, and remember that a deposit page is one of the few things about a network you can verify without spending anything.
Three families of advertising platform, and why the difference decides your shortlist
Advertising platforms fall into three families that behave differently long before you compare creative specs: walled gardens that sell their own inventory, open-web ad networks that aggregate independent publishers, and demand-side platforms that buy programmatically across exchanges. Which family you can use is usually settled by your vertical and your budget rather than your preference.
Walled gardens — Google, Meta, Amazon, TikTok, LinkedIn — own both the audience and the data, which buys targeting nobody else can replicate. You pay for it in control. Placements are invisible, category policy is enforced by automated review, and whole verticals sit permanently outside the door.
Open-web networks work the other way round. AdsCompass, PropellerAds and Adsterra own no inventory; they auction what thousands of independent sites and apps put up for sale, usually over OpenRTB. Deposits are small, source-level data is exposed, and the verticals walled gardens reject find a home here. In exchange, traffic quality becomes your job rather than the platform's.
Demand-side platforms such as The Trade Desk and DV360 sit in a third category most advertisers never enter, because there is no realistic self-serve door: access runs through an agency seat and monthly commitments start in five figures. Amazon's own DSP is the clearest published example at roughly $10,000 to $15,000 a month through managed service.
AdsCompass: eight ad formats, a $50 card deposit, and bidding you do by hand
AdsCompass has run since 2013 and sells eight ad formats to advertisers on CPC or CPM across 200-plus countries: push, in-page push, native, popunder, banner, video pre-roll, and two Telegram Mini App units — Rewarded Post and Rewarded Video. Publishers monetise six of them; the Telegram pair is advertiser-only, and no other network in the comparison above sells Telegram Mini App inventory at all. Deposits clear through Capitalist, Bitcoin, USDT TRC-20, PayPal, Stripe, Paxum, WebMoney, bank cards and wire.
Targeting reaches further than the deposit suggests: countries and cities, device, OS and browser down to version, ISP and mobile carrier, browser language, connection type, plus two filters that thin out non-human traffic before it costs anything — exclusion of IPv6 addresses and exclusion of proxy connections.
Source ID bidding is the reason to be here. Also called micro bidding, it prices individual publisher source IDs separately: raise the bid where conversion rate holds, cut it where clicks arrive without action, and volume survives while cost per conversion falls. Around it sit black and white lists by IP, ISP and source ID, an Audiences section for retargeting with upload and auto-collection rules, a frequency cap per unique IP per day, dayparting in your own timezone, daily and hourly budgets, and a choice between even pacing across 24 hours and spending as fast as the auction allows.
Measurement runs on S2S postback and an SST pixel rather than browser cookies, with macros for campaign ID, creative ID, price, IP, source ID, user agent and click ID. Integration with other systems goes over OpenRTB, XML or JSON feed, which is how another network plugs into the same pool. Support runs through a personal manager plus a 24/7 Telegram channel in English and Russian.
Three things worth knowing before you deposit
There is no CPA-goal automation: bidding and source pruning are manual work, and PropellerAds' CPA Goal will save hours that AdsCompass will not. The published volumes — 900 million daily impressions, 30 million daily clicks, 6,500 advertisers — are company and review-site figures that nobody audits. And publisher-side requirements are genuinely unclear, because the network moderates case by case and publishes no criteria, which is the same reason there is no public rate card for the traffic you are about to buy.
The vertical list is the other reason buyers land here. iGaming, dating and software are the core categories, with e-commerce, sweepstakes, crypto, finance, nutra, mobile apps, surveys and utilities also running, and adult traffic permitted — a line PropellerAds does not cross. Google and Meta reject most of that list outright, so a feature-by-feature comparison across the two families is less like-for-like than it looks.
| Network | Since | Card deposit | GEOs | Auto-optimisation | Adult allowed |
|---|---|---|---|---|---|
| AdsCompass | 2013 | $50 | 200+ | Manual, source-level control | Yes |
| PropellerAds | 2011 | $100 | 195+ | Strong: CPA Goal, SmartCPC | No |
| RichAds | 2018 | $100 | 220+ | Strong | Restricted |
| HilltopAds | 2013 | $100 | 250+ | Moderate | Yes |
| Adsterra | 2013 | $100 | 248+ | Moderate | Yes |
Google Ads and Microsoft Advertising: $5.42 a click and $66.69 a lead, as medians
Search advertising cost a median $5.42 per click and $66.69 per lead across 23 industries in the 2026 edition of LocaliQ and WordStream's benchmark report, built from 13,474 US campaigns running between April 2025 and March 2026. Click-through rate averaged 6.64%, conversion rate 8.18%. Two qualifications get dropped almost everywhere that figure is quoted: the numbers are medians rather than means, and the dataset blends Google Ads with Microsoft Advertising — which is why the two platforms share a section here.
The spread beats the average for planning. Arts and Entertainment paid $1.63 a click and Restaurants and Food $2.05, while Attorneys and Legal Services paid $9.87 and carried the highest cost per lead of any industry at $131.63. Conversion rates diverge harder still, from 16.22% in Animals and Pets down to 2.64% in Finance and Insurance, so a click price means nothing except next to the rate it converts at.
One finding in that report cuts against most commentary published last year: cost per lead fell for the first time in five years, down from $70.11, while clicks got dearer. Auctions grew more expensive and conversion improved enough to more than absorb it — the reverse of the story everyone told about rising costs.
Microsoft Advertising earns its place on inventory other advertisers under-bid and on one-click import from Google Ads, which makes a test almost free in setup time. Its limit is query volume: on thin keyword sets, significance arrives slowly.
Meta and TikTok: the floor that keeps a campaign alive is not the one that makes it learn
Meta and TikTok publish the friendliest entry numbers of any major advertising platform and enforce the harshest data requirements behind them. Meta accepts $1 a day for impression-optimised delivery and $5 a day for campaigns optimised toward clicks or conversions, and if you set a cost-per-result goal it wants a daily budget of at least five times that goal. TikTok's budget documentation fixes $50 a day per campaign and $20 a day per ad group, computes lifetime budgets as $20 multiplied by scheduled days, and sets a higher $30 floor for web conversion campaigns in North America and EMEA.
Both then want roughly 50 conversion events per ad set per week before the bidder stops guessing. Run that against a $25 target cost per action and the working floor lands near $179 a day per ad group, around nine times TikTok's printed minimum. Beneath it the campaign still delivers. It simply never learns.
Size the budget from target CPA multiplied by 50 and divided by seven, then leave it alone: TikTok's own guidance is to raise a budget by no more than 40% per adjustment while a campaign is still learning, because a bigger jump restarts the phase you are paying to finish.
LinkedIn Ads: $10 a day, $100 lifetime, and a $2 bid floor
LinkedIn Ads enforces a $10 daily minimum, a $100 lifetime minimum on new campaigns and a $2 floor on both CPC and CPM bids, with Message Ads set higher again at $25 a day. Against sponsored content clicks that typically run $5 to $12 in B2B, ten dollars buys one or two visits a day: a month of that produces around thirty clicks and, in practice, no pipeline.
The premium is worth paying in exactly one situation — when job title, seniority and company size predict who buys. Director-level targeting runs two to three times the click price of individual contributors, and C-suite targeting in competitive categories runs higher again. That gap is the price of employment data no other platform holds. Outside that case you are funding a filter with no bearing on your offer.
Amazon Ads: $1.18 a click at the shelf, and one structural condition
Amazon Ads charges per click from a technical minimum of $1 a day on Sponsored Products, with a blended average cost per click near $1.18 across formats in 2026 — up 8 to 12% year on year, and far below search, because the shopper already has a basket open. Sponsored Products sit at $0.75 to $1.50, Sponsored Brands at $1.10 to $2.50, and Sponsored Display has moved fastest, averaging around $3.72 after a 49% annual rise.
Two mechanics catch people out. Daily budgets are averaged across the calendar month rather than enforced each day, so a campaign created after March 2023 can spend up to double its daily figure on a high-traffic day and balance it later — useful during Prime Day, alarming if you assumed a hard cap. And Sponsored Products has no lifetime budget at all; that option belongs to Sponsored Brands, at a $100 minimum.
The real constraint is structural rather than financial. Amazon Ads only pays back if Amazon is your sales channel, which brings inventory, fulfilment and rival sellers undercutting you in the same result row. Advertisers who treat it as a traffic source for their own store rarely make that arithmetic work.
Taboola and Teads: native inventory, and a disclosure that must precede the click
Outbrain no longer exists as a brand: the company completed its corporate renaming to Teads Holding Co. on 6 June 2025 according to its own SEC filing, began trading as TEAD on 10 June 2025, and had bought Teads that February for about $900 million. Comparison articles still listing Taboola and Outbrain as two live options are working from stale sources. The auction underneath is the same; the dashboard, the reps and the invoices say Teads, and the combined business now runs direct relationships with more than 10,000 publishers across 36 countries.
Native carries a legal duty the other formats do not. The FTC's native advertising guide for businesses puts the disclosure before the reader reaches your page — above the headline, on the thumbnail, wherever the eye lands first. A label that appears after the click has already misled somebody. Advertorial buyers routinely mark the landing page and leave the widget clean, which is precisely the arrangement the guidance was written to stop.
OpenAI Ads: no minimum spend since 5 May 2026, and measurement that now exists
OpenAI Ads dropped its minimum spend entirely on 5 May 2026, when the self-serve Ads Manager opened to all US businesses alongside CPC bidding at a suggested $3 to $5 and — contrary to most commentary written before that date — a Conversions API and measurement pixel. The compression took 86 days: the pilot launched on 9 February 2026 at a $60 CPM with a minimum in the $200,000 to $250,000 range and CPM-only buying through agency partners, fell to $50,000 with the April beta, then to nothing.
What is still missing shapes the test more than the price does. A conversions objective is listed in the interface as coming rather than shipped, so there is no CPA bidding yet; ads reach only logged-in adults on the Free and Go tiers in the US, Canada, Australia and New Zealand, with paid tiers ad-free; and early click-through rate came in around 0.91%, roughly seven times below the search benchmark. Give it a test budget and a tracker, not a quarterly plan — and wire the Conversions API before the first dollar, because ChatGPT clicks often land in in-app browsers where a client-side pixel loses conversions and makes the channel look worse than it is.
What changed for every advertising platform in 2026: cookies stayed, Privacy Sandbox went
Third-party cookies survived and their replacement did not. Google retired ten Privacy Sandbox technologies on 17 October 2025 — Topics, Protected Audience, Attribution Reporting and IP Protection among them — citing low adoption, with deprecation starting in Chrome 144 in January 2026 and removal targeted for Chrome 150. CHIPS, FedCM and Private State Tokens survive. In the same month the UK's Competition and Markets Authority closed its four-year investigation and released Google from its Privacy Sandbox commitments, since there was no longer a cookie deprecation to police.
Read it narrowly. Safari, Firefox and Brave still block third-party cookies by default, and consent obligations under GDPR and US state law are untouched by any of it. Nothing about the retirement removes a cookie banner.
For platform selection the conclusion is dull and useful. Attribution that leans on a browser you do not control is permanently fragile, so server-to-server postback tied to your own click IDs is the setup that survives whichever way the browser vendors move next. Every open-web network here supports it, and the walled gardens each run a conversions API of their own.
Which advertising platform fits your goal
Match the platform to the job rather than to the budget, because the wrong family costs more than the wrong bid. The table maps the seven most common goals onto the platforms that actually serve them.
| Goal | Platform | Reason |
|---|---|---|
| Buy volume on the open web, or run a vertical Google rejects | AdsCompass, PropellerAds, Adsterra | Deposit-based entry, source-level control, permissive category rules |
| Capture declared purchase intent | Google Ads, Microsoft Advertising | $5.42 median click against an 8.18% conversion rate |
| Sell physical products at consumer scale | Meta, TikTok, Amazon Ads | Cheap impressions, or $1.18 clicks at the point of sale |
| Reach decision-makers by job title | LinkedIn Ads | Employment data no other platform holds |
| Distribute long-form and advertorial content | Taboola, Teads | Publisher context, with FTC disclosure handled before the click |
| Test a new surface early | OpenAI Ads | No minimum spend, narrow reach, no CPA bidding yet |
| Run cross-channel programmatic at scale | The Trade Desk, DV360, Amazon DSP | Agency seat and five-figure monthly commitment |
Frequently asked questions
Which advertising platform has the lowest entry cost?
Google Ads and Microsoft Advertising take no deposit at all, and Meta and Amazon Ads accept $1 a day. Among deposit-based open-web networks, AdsCompass publishes the lowest figure at $50, against $100 at PropellerAds, Adsterra and HilltopAds. Every one of those floors rises with the payment method: wire transfer costs $500 to $1,000 depending on the network.
What are the best advertising platforms for a small budget?
For under $500 a month, search and open-web networks work and social bidders usually do not. Google Ads and Microsoft Advertising charge per click with no deposit, and AdsCompass, PropellerAds and Adsterra price per click or per thousand impressions with source-level controls. Meta, TikTok and Taboola all run machine-learning bidders that need roughly 50 conversion events per week before they optimise, which costs far more than their published minimums.
How do open-web ad networks differ from Google and Meta?
Open-web networks expose the placement — you see source IDs, bid on them individually and blacklist what fails — and accept verticals such as iGaming, dating and adult that Google and Meta prohibit outright. The trade-off is traffic quality, which you police with filters, frequency caps and postback data rather than trusting the platform.
How much should a first campaign budget be?
On any platform with a machine-learning bidder — Meta, TikTok, Taboola, Google's Smart Bidding — multiply your target cost per action by 50 and divide by seven for a realistic daily figure per ad set. At a $25 target CPA that is about $179 a day. On manual networks such as AdsCompass the formula does not apply, because you read source-level results instead of feeding a learning phase.
Are ChatGPT ads worth testing in 2026?
OpenAI Ads is worth a test budget rather than a quarterly plan. Since 5 May 2026 there is no minimum spend, CPC bidding runs at a suggested $3 to $5, and a Conversions API and pixel now measure post-click events. Reach is limited to logged-in adults on the Free and Go tiers, a conversions objective is still listed as coming, and early click-through rates around 0.91% sit far below search.
Do third-party cookies still matter for ad targeting?
Chrome kept them and retired the Privacy Sandbox APIs built to replace them, with removal running from Chrome 144 into Chrome 150 during 2026. Safari, Firefox and Brave keep blocking by default and consent law is unchanged, so server-side postback tracking tied to your own click IDs works across all three positions.
