Setting up a Google Ads account for the first time is straightforward in theory. In practice, the decisions you make in the first hour, campaign structure, match types, bidding strategy, and conversion tracking, determine whether the account will perform or bleed budget for months. This guide covers the setup process specifically for small businesses operating in Japan.

Start with conversion tracking, not keywords

Most guides tell you to start with keyword research. We disagree. If your conversion tracking is not set up correctly before the first click, every optimization decision you make will be based on bad data. Install Google Tag Manager on your site first, then configure a GA4 purchase or lead event, then import that event into Google Ads as a conversion action. Only then should you start building campaigns.

Keyword research for Japanese search behavior

Japanese search queries mix hiragana, katakana, and kanji in ways that differ from how the same concept is searched in English. A dental clinic in Tokyo will be searched as '歯科 渋谷', '歯医者 渋谷', and '渋谷 歯科医院' by different users. All three need to be in your keyword list. Use Google's Keyword Planner with Japanese as the language setting, and cross-reference with the search terms from any existing campaigns.

Campaign structure for a new account

For a new account with a budget under ¥300,000 per month, we recommend starting with one Search campaign, two to four tightly themed ad groups, and phrase match keywords. Broad match requires strong conversion data to work well. Without at least 30 conversions per month, broad match will spend on irrelevant queries faster than you can add negatives. Start narrow, then expand once the data supports it.

Bidding strategy selection

New accounts should start on Manual CPC or Maximize Clicks with a bid cap. Smart Bidding strategies like Target CPA require a minimum of 30 to 50 conversions in the past 30 days to function reliably. Starting a new account on Target CPA with no conversion history puts the algorithm in a permanent learning phase. Build the conversion volume first, then switch to Smart Bidding.

The first 30 days

In the first 30 days, your job is to collect data, not to optimize aggressively. Review the search terms report every three to four days and add negatives for clearly irrelevant queries. Do not change bids or budgets more than once a week. Let the algorithm stabilize. After 30 days, you will have enough data to make informed decisions about which ad groups to scale and which to pause.

Setting up an account correctly from the start saves months of cleanup work later. If you would rather have a professional handle the build, our Google Ads setup service covers everything in this guide and has your first campaign live within five business days.
