Google Ads is the best online ad service for most startups because it has no minimum daily budget, reaches people who are searching with clear intent, and covers Search, YouTube, Display, and Shopping from one account. Meta Ads is the lowest-cost social start, with a $1 per day floor for impression ad sets in the US, while LinkedIn Ads is the best choice for business buyers, with a $10 per day floor and job title targeting. TikTok Ads has the highest self-serve floor here, at $50 per day at campaign level, so test it only after a cheaper channel has shown that short video can sell the offer.
Startups need ad services that let a small test run, show clear results, and stop without a long contract. The eight services below all run on an auction, so the final cost per click or per thousand impressions changes with audience, creative, and competition. What stays fixed is the floor each service sets and the limit that forces a larger budget.

The 8 best best online ad services for startups, in detail
Google Ads
Best for: Search intent and Shopping
Google Ads suits a startup that sells a product people already search for by name or by problem. Search ads appear when intent is high, while Performance Max can place the same offer across Search, YouTube, Display, Discover, Gmail, and Maps from one campaign. Keyword Planner gives bid estimates, so a founder can see which terms are likely to cost more before spending.
- Google states that there is no minimum ad spend, and the advertiser sets an average daily budget for each campaign.
- Monthly spend for most campaigns is capped at the average daily budget multiplied by 30.4, while a single day can spend up to twice the average daily
- A $10 daily budget therefore allows about $304 in a month.
Pros
- No minimum spend
- Search, YouTube, Display, and Shopping in one account
- Keyword Planner gives bid estimates
Cons
- Demand Gen enforces a minimum budget with no figure shown on its help page
- daily spend can reach twice the average daily budget on a busy day
Meta Ads
Best for: Low-cost social reach
Meta Ads covers Facebook and Instagram from Ads Manager, with feed, Stories, Reels, and Marketplace placements. The low floor makes it a useful first social test for a consumer startup, a local service, or an app with a clear visual offer. Interest, behaviour, and custom audience targeting let a small team test two or three audience ideas without building a large campaign structure.
- The floor is not the working budget.
- Meta sets the minimum by objective, optimisation event, bid strategy, buying type, currency, and schedule.
- For impression ad sets in the US, the floor is $1 per day, while ad sets optimised for clicks, conversions, or other lower-frequency events need $5 pe
- For a cost-per-result goal, the daily budget must be at least five times the target cost, so a $10 target cost needs at least $50 per day.
Pros
- $1 per day floor for impression ad sets in the US
- Facebook and Instagram placements in one manager
- Advantage campaign budget can move spend across ad sets
Cons
- Cost-per-result goals need a daily budget of at least five times the target cost
- the learning phase needs about 50 optimisation events in seven days
LinkedIn Ads
Best for: Business buyers by job title
LinkedIn Ads is the best fit in this list for a startup that sells to companies, especially when the buyer is a named role such as a finance director, an operations lead, or a founder. Targeting by job title, company size, industry, and seniority narrows spend to people who can approve a purchase, which is hard to do on a broad social feed. Formats include single image, video, carousel, message, and text ads.
- The entry rules are clear and the working budget is higher than the floor.
- LinkedIn states that the minimum daily budget is $10 for any ad format, and the minimum lifetime budget for a new campaign is $100.
- Once a campaign launches, the lifetime minimum becomes $10 multiplied by the total days scheduled.
- Campaign Manager suggests $25 per day for new advertisers and $50 to $100 per day for existing advertisers who use US dollars.
Pros
- Targeting by job title, company, and seniority
- $10 per day floor for any ad format
- Campaign Manager suggests $25 per day for new advertisers
Cons
- Minimum lifetime budget is $100 for a new campaign
- audience needs at least 300 members, with 50,000 suggested for results
TikTok Ads
Best for: Short video for younger buyers
TikTok Ads suits a startup with a product that looks good in short vertical video and a buyer who spends time in the TikTok feed. Spark Ads let an advertiser use an existing TikTok video, with its likes, comments, and shares, as the ad creative, which keeps the ad close to the style of the feed. Smart+ can automate targeting and bidding for advertisers who want fewer manual settings.
- The budget floor is the highest self-serve floor in this list, and the lifetime rule is the detail most roundups miss.
- TikTok states that the minimum budget is $50 at campaign level and $20 at ad group level.
- For a lifetime ad group budget, the floor is $20 multiplied by scheduled days, so a 31-day ad group needs at least $620.
- The budget type cannot be changed after a campaign or ad group is live, although the amount can change.
Pros
- $20 per day floor at ad group level
- Spark Ads use existing TikTok videos
- Smart+ can automate targeting and bidding
Cons
- Budget type cannot change after a campaign or ad group is live
- lifetime ad group floor is $20 multiplied by scheduled days
Microsoft Advertising
Best for: Lower-cost search reach
Microsoft Advertising places search ads on Bing and partner sites, including Yahoo, AOL, and DuckDuckGo, and it also offers audience, video, and shopping formats. It suits a startup that already runs Google Ads and wants extra search reach without building a second campaign from scratch, because Google Ads campaigns can be imported. The audience skews older and more desktop-based than the audience on TikTok or Snapchat.
- The entry floor is the lowest in this list.
- Microsoft lists a minimum keyword bid of $0.05, a minimum daily budget of $0.05, and a minimum monthly budget of $5 in USD, with no minimum fee to ope
- Budgets are set per campaign as daily, shared across campaigns, or lifetime for audience campaigns only.
- Microsoft treats the daily budget as a target and works out the real limit over a month, so a single day can run above or below the set amount.
Pros
- No minimum fee
- $0.05 minimum keyword bid in USD
- Google Ads campaigns can be imported
Cons
- Minimum monthly budget is $5 in USD
- daily budget is treated as a target, so single days can run above or below it
Reddit Ads
Best for: Niche communities
Reddit Ads suits a startup whose buyers gather in named communities, such as a hobby, a profession, a game, or a technical topic. Community targeting places an ad in a chosen subreddit, while interest and keyword targeting reach people by topic across the site. Formats include image, video, carousel, and free-form posts that look close to a normal Reddit post, and they can run in the feed and in conversation threads.
- The cost rules are simple at the low end and strict at the high end.
- Reddit states that fees start from about $5 per day, and its help pages set a $5 daily minimum.
- Billing follows the objective, with cost per thousand impressions, cost per click, or cost per video view, and the minimum cost-per-view bid is $0.01.
- An ad group can overspend its budget by up to 20% because delivery runs on a real-time auction, so a $5 daily budget can spend up to $6 on a busy day.
Pros
- Targeting by community, interest, and keyword
- $5 per day floor
- $0.01 minimum cost-per-view bid
Cons
- An ad group can overspend its budget by up to 20%
- large takeover placements need a managed sales team
Snapchat Ads
Best for: Young mobile buyers
Snapchat Ads suits a startup that sells to younger mobile buyers with full-screen vertical video and image ads in Stories, Spotlight, Discover, and Chat. The self-serve manager lets a small team set daily or lifetime budgets, choose one of five objectives, and use the Snap Pixel to track site actions. The price page states the floor and the working range in the same paragraph, which is useful for planning.
- Snap states that the minimum spend per day is $5, although it recommends $20 to $50 per day to help an ad complete the Exploration Phase, which typica
- Snap also offers $75 in ad credit when a new advertiser spends $50, with terms applying.
- A $5 test can launch, but it should run for at least four days at $20 to $50 per day for a clean read on cost per result.
Pros
- $5 per day floor
- Snap recommends $20 to $50 per day to complete exploration
- $75 ad credit when a new advertiser spends $50
Cons
- Exploration phase typically takes four days or more
- $5 per day rarely gathers enough data to complete exploration
X Ads
Best for: Low-cost tests and live discussion
X Ads suits a startup that wants to test a message in live discussion, reach people by keyword, interest, or follower look-alike, and run a small auction test without a platform minimum. Formats include promoted posts, vertical video, Amplify pre-roll, and collection ads, with objectives for reach, video views, website clicks, app installs, and engagements. The auction is second-price in style, so the winning bid pays just above the next highest bid, up to the set maximum.
- The entry rules are the most open in this list, with one gate that matters.
- X states that there is no minimum spend required for X Ads, and the lowest bid it accepts is $0.01 per desired action.
- An advertiser sets a daily budget at ad group level, and X states that it will not exceed that daily budget.
- Before ads can run, the account must be verified through Verified Organizations or an X Premium plan.
Pros
- No minimum spend
- $0.01 minimum bid per desired action
- daily budget is not exceeded
Cons
- Account must be verified through Verified Organizations or an X Premium plan
- billing runs at least once every seven days
How we chose
We chose services that a startup can open as a self-serve account, set a daily budget, and run without a managed sales contract. Every service in this list has a stated minimum budget or a stated no-minimum rule on an official vendor page opened on 2026-11-12, and every starting price comes from that official page or from the vendor help page cited in Sources.
We did not test any tool hands-on. Prices and plan limits come from official vendor pricing pages and docs opened today, 2026-11-12. We did not use customer counts, awards, or review scores to rank the services.
Pick by daily budget
| Service | Minimum per day | 7 days at minimum | 30 days at minimum |
|---|---|---|---|
| Google Ads | No minimum | $0 at the floor | $0 at the floor |
| Meta Ads | $1 | $7 | $30 |
| LinkedIn Ads | $10 | $70 | $300 |
| TikTok Ads | $50 | $350 | $1,500 |
| Microsoft Advertising | $0.05 | $0.35 | $1.50 |
| Reddit Ads | $5 | $35 | $150 |
| Snapchat Ads | $5 | $35 | $150 |
| X Ads | No minimum spend | Set by the advertiser | Set by the advertiser |
Use this table as a floor check, not as a test plan. A $7 week on Meta Ads can launch, but it will not gather 50 optimisation events unless the cost per event is very low. For a first test, set $10 to $20 per day on Google Ads, Meta Ads, Reddit Ads, or Snapchat Ads, $25 on LinkedIn Ads, and $50 on TikTok Ads, then run for at least seven days.
