Google Ads has no fixed price list. It is an auction that charges you per click, so you set your own daily budget, anything from a few hundred baht to six figures a month, and you pay only when someone clicks the ad, not when it appears. The cost per click is not a number Google sets in advance. It comes out of the competition for the keywords you chose, the quality of your ad, and the quality of the page you send people to.
This guide explains where the money actually goes, how to work out a starting budget, how agency fees are structured, and how to tell whether the spend is paying for itself.
How Google Ads pricing works and what the auction does
Every time someone searches, Google runs a fresh auction in a fraction of a second. Advertisers whose keywords match the query are ranked by Ad Rank, which is not simply whoever bid the most. The calculation includes your bid, the quality of your ad at auction time, the rank thresholds for each ad position, the context of the search such as device, location and time of day, and the expected impact of your ad assets.
The consequence matters more than the mechanics. You do not pay your bid. You pay the minimum needed to beat the advertiser ranked below you, divided by your quality. A site with a landing page that matches the keyword and ad copy people actually want to click can pay less per click than a competitor bidding higher.
Quality Score in Google Ads runs from 1 to 10 and has three components: expected click-through rate, ad relevance to the keyword, and landing page experience. Each is reported as below average, average, or above average. Treat it as a diagnostic that tells you which of the three to fix, not a grade to chase to 10.
One more mechanic that trips people up is the daily budget. Google can spend up to twice your daily budget on a given day to make up for quiet days, but your monthly total will not exceed your daily budget multiplied by the average number of days in a month, 30.4. Set a daily budget of 500 baht and the monthly ceiling for that campaign is roughly 15,200 baht, regardless of individual heavy days.
What budget do you need to start running Google Ads
Google sets no minimum spend, no contract, and no account opening fee. Technically you can start with a few tens of baht a day. But the useful question is not what the system accepts. It is how much buys enough clicks to show you what works and what does not.
Work backwards from your own numbers. Start with the bid range for the keywords you intend to use, multiply by the clicks you need per day to produce an enquiry or an order, then multiply by the days in the month. If the total is more than you can carry, the fix is not to cut the budget until you get one or two clicks a day. The fix is to narrow the keyword set to the terms where people are ready to buy, and to narrow the geography as well.
Underfunded accounts all hit the same wall: the data is too thin to decide anything. Automated bidding strategies such as Maximize Conversions or Target CPA need a run of accumulated conversions before they can learn. If your budget produces only a handful of conversions a month, automation makes results swing harder. In that situation, manual CPC or Maximize Clicks with a bid ceiling usually keeps costs closer to what you planned.
What is the average CPC by industry in Thailand
The honest answer is that there is no official figure. Google does not publish average cost per click by industry for Thailand. Nearly every table circulating on websites and in sales decks comes from a tool vendor or an agency summarising the accounts it happens to manage. That is one sample, not a market standard. Setting a budget straight off those numbers without checking your own keywords is how plans go wrong.
Why a single average number is not usable
Two accounts in the same industry can pay several times different rates per click, because the variables that set the price are not the same. Different keyword sets. Different match types. A keyword containing the Thai word for price pulls a different crowd than a general question. Different quality scores, different targeting areas, different times of year, and a different number of competitors bidding on the same term that month. An average blends away exactly the differences that matter.
How to find the click price range for your own business
The closest answer you can get without spending money first comes from Keyword Planner, under the Tools menu in Google Ads. Open Discover new keywords, enter the terms your customers would type, set the location to Thailand and the language to Thai, then read the two columns named Top of page bid low range and Top of page bid high range. Those are the amounts other advertisers actually pay to hold the top of the results page for that term.
That range is not yet the google ads cost per click you will pay, because it does not know your quality score. It is a planning frame. Take the midpoint between the low and high figures, allow room for error in both directions, and after two or three weeks of live traffic switch to the keyword report inside your own account, because that is your real price rather than the market's.
An example calculation with made-up numbers
The figures in this paragraph are round numbers invented to demonstrate the method. They are not Thai market averages. Assume a CPC of 20 baht and a landing page conversion rate of 2 percent. You would need roughly 50 clicks to produce one enquiry, so the cost per enquiry is 1,000 baht. If sales close one enquiry in five, the cost of one new customer is 5,000 baht. That last figure is the one you compare against your profit per customer, not the cost per click.
Change one assumption and you can see which variable carries the most weight. Move the conversion rate from 2 percent to 4 percent and the cost per enquiry halves without the click price moving at all. That is why fixing the landing page usually pays off faster than grinding down bids.
How agency fees are calculated, percentage or flat retainer
Management fees are always separate from the media you pay Google. Ad spend goes straight into your Google account. The fee pays for the people who build the campaign structure, write the ads, read the reports, and fix what breaks. A few fee models are common.
- Percentage of ad spend. The fee moves with the budget, which suits accounts whose spend swings with the season. The thing to watch is the built-in incentive to recommend a bigger budget.
- Flat monthly retainer. The fee stays the same whatever the spend, which makes costs easy to forecast, but the scope needs to be written down: how many campaigns, how many new ad sets per month.
- Hybrid. A minimum retainer plus a percentage once spend passes an agreed level.
- Performance based. The fee is tied to conversions or revenue. This one only works if both sides trust the measurement setup first, otherwise every month turns into an argument about the numbers.
What you ask before signing matters more than the fee itself. First, whose name is on the Google Ads account? If the agency opens it under its own name and the relationship ends, the history that trains the bidding system leaves with them. Second, is the setup fee separate from the monthly fee? Third, are the reports live account numbers you can log in and check yourself, or a slide summary? The search advertising management service at Relevant Audience gives clients full access to their own accounts, because the data in the account belongs to the business that paid for it.
What monthly budget should you start with
Rather than looking for a standard figure, calculate your own minimum from three inputs: the bid range from Keyword Planner, the conversion rate you expect on your landing page, and the number of enquiries per month that your sales team can handle and that justifies running the campaign at all.
Divide the enquiries you want by the conversion rate to get the clicks you need to buy, multiply by the cost per click for the monthly budget, then add roughly a quarter on top for the first month of testing. Some of the first month's money goes to irrelevant queries before you have collected a full negative keyword list.
If the resulting number is beyond what you can spend, three adjustments actually work. Reduce the geography and target a province or a radius around the shop instead of the whole country. Cut broad keywords and keep only clear purchase intent, such as terms containing price, hire, near me, or a specific product model. Or start with your own brand terms, which usually carry the lowest cost per click, and expand once you have conversion data.
How Search, Display and Shopping pricing differ
Campaign types differ in more than appearance. They differ in what you are billed for and what pushes the price around. The table below covers the mechanics without price figures, since real prices depend on each account's keywords and products.
| Campaign type | What you are billed for | What moves the price |
|---|---|---|
| Search | Per click on a results page | Number of competitors bidding the same keyword, query intent, and quality score |
| Display | Per click or per thousand impressions | Audience selected, placements shown on, and creative format |
| Shopping | Per click on a product card | Your price against competitors on the same page, feed quality, and product category |
| Video on YouTube | Per view or per thousand impressions | Ad format, length, and how contested the audience is |
In practice Search tends to cost more per click than Display, because someone typing a query is showing clearer intent than someone reading an article. A cheaper click does not mean better value, though. Compare cost per conversion every time. There is more detail on the display advertising service page and the Google Shopping service page.
How you pay Google, and is there VAT
Google Ads has three main payment settings. Automatic payments charge a card once your accrued costs hit a billing threshold or when the monthly billing date arrives, whichever comes first. Manual payments mean you top up first and ads run until the balance runs out. Monthly invoicing is a credit line with eligibility requirements that you have to apply for.
Two settings must be right on the day you open the account because they cannot be changed later: currency and time zone. A Thai business billing in baht should pick baht and the Bangkok time zone. Otherwise every report is offset by a day from your accounting system and reconciling invoices stays awkward for the life of the account.
On tax, Thailand's VAT rate is 7 percent. Whether your invoice carries VAT depends on which selling entity issues the bill for your account and whether you entered a Thai tax ID in the payment profile. The reliable way to check is to open Billing, then Documents, and look at the most recent invoice for a VAT line. Advertising costs paid by a Thai company also interact with withholding tax, and the treatment depends on the payee and the contract, so confirm with your accountant before you book the entry rather than relying on an article online.
How to judge whether it pays off using ROAS
ROAS is conversion value divided by ad cost. Spend 10,000 baht and generate 40,000 baht in sales and the ROAS is 4, or 400 percent. That tells you how much revenue each baht of ad spend produced. It does not yet tell you whether you made a profit.
The number you need first is break-even ROAS, which is one divided by your gross margin. Assume a 40 percent gross margin and the break-even ROAS is 2.5. Below 2.5 the campaign loses money the harder you run it. Above it, you start earning. Every figure in this paragraph is an invented example to show the formula. Substitute your own real margin.
For businesses that do not sell on the website, such as services or project work, use cost per enquiry multiplied by your close rate and compare that with profit per deal. What has to exist first is measurement that counts real events: call taps, chat button taps, form submissions. Offline conversions should be imported back into the account when deals actually close. Without that, automated bidding learns from the wrong signal and goes hunting for cheap enquiries that never become customers.
People who have already visited the site and not bought usually carry the lowest cost per conversion, which is why a remarketing campaign belongs in the same budget from the start rather than being added later.
What this means in the Thai market
Three things make budgeting in Thailand different from English-language playbooks. Thai search queries have no spaces between words, and many Thai users mix English and Thai inside a single query, typing a product model in English followed by the Thai word for price. A complete keyword set needs both forms, and the search terms report needs checking more often in the first month, because broad match in Thai pulls in unrelated queries easily.
Second, the closing channel. Plenty of buyers click an ad and never fill in a form. They move into chat instead. If chat button taps and call taps are not configured as conversions, reports will show a campaign failing while real enquiries arrive, and budget gets pulled toward campaigns that are easier to measure but lower in quality.
Third, seasonality. Thai festivals, e-commerce double-digit sale dates, and corporate budget cycles all move the number of competitors in the auction. A budget held flat all year buys fewer clicks in the heavy months. Planning budgets month by month and watching impression share lost to budget shows you which months need topping up.
Frequently asked questions about Google Ads costs
Is there a minimum spend for Google Ads
No. Google sets no minimum spend and no contract, so you choose the daily budget and can pause or change it at any time. The real constraint is data volume: a budget that buys only a few clicks a day takes a very long time to show which keywords work.
Does bidding more always get you the top position
Not always, because ad position is calculated from your bid together with ad quality, landing page experience, and the rank threshold for each position. An advertiser with better quality can outrank a higher bidder and often pays less per click as well.
Is the money paid to Google the same as the agency fee
They are separate. Media cost goes to Google directly based on clicks, while the management fee goes to the service provider for running the account. Before signing, get it in writing whether the fee is a percentage, a flat retainer, or a hybrid, and whether setup work is included or billed separately.
Why is my cost per click higher this month than last
The most common cause is more competitors bidding on the same keywords during that period, followed by a drop in quality score after a landing page or ad copy change, and by new higher-priced queries starting to match your broad keywords. Open the search terms report and the auction insights report and compare the two months before drawing a conclusion.
With a limited budget, should you start with Search or Shopping
If you sell products with proper product detail pages and checkout on your site, Shopping usually delivers a better cost per order because shoppers see the image and price before clicking. If you sell services or anything that needs a conversation before quoting, start with Search on clear purchase-intent keywords and expand from there.
In short
The price of Google Ads is not a number anyone can quote you the same way twice. It falls out of the keywords you pick, the quality of your ads and pages, how contested the auction is at that moment, and how well you can measure results. Pull a bid range from Keyword Planner as a starting point, calculate backwards from the enquiries you need, and judge the result on ROAS or real cost per deal rather than on cost per click alone.
If you would rather have figures based on your own keywords than a floating average, the team behind the Google Ads management service at Relevant Audience can assess your likely click price range, campaign structure, and the budget that fits your target.
