Google Ads is the system that lets you buy visibility on Google. Type "handmade ceramic mug" into Google and the first results marked "Sponsored" are ads. Someone paid to be there, and they pay again each time a person clicks. The same system runs the product tiles on Google Shopping, the video ads before a YouTube clip and the banners on millions of partner websites.

It concerns you as soon as people search for what you sell. A creator with a course, a brand with 40 products, a one-person store shipping candles: all three can open an account with $10 a day. The question is never whether you can run Google Ads, but whether a click costs less than what it brings back.

What is Google Ads?

Google Ads is an auction-based advertising platform. You describe who you want to reach (a search query, an audience, a placement), you write or upload the ad, you set a budget and a maximum price, and Google decides in real time whether to show your ad and where. You are charged only when a measurable event happens, most often a click.

Several campaign types live inside the same account:

  • Search campaigns: text ads shown on Google results pages when someone types a query that matches your keywords. This is the classic form of search engine advertising.
  • Shopping campaigns: product tiles with a photo, a price and your store name, fed by a product feed. See Google Shopping.
  • Performance Max: one campaign that spreads across Search, Shopping, YouTube, Gmail, Maps and Display, steered by a conversion goal rather than keywords.
  • Display and video: image and video ads across partner sites and YouTube, mostly bought on impressions rather than clicks.

What Google Ads is not: it is not SEO. Organic results are earned with content and cannot be bought. It is also not a set-and-forget channel. The auction moves daily, competitors change their bids, and a campaign left alone for three months will usually drift.

Vocabulary you will meet on day one: keyword (the query you want to match), match type (how loosely Google interprets that keyword), Quality Score (a 1 to 10 rating of how relevant your ad and landing page are), conversion (the action you count as success, usually a purchase) and ROAS (return on ad spend, revenue divided by ad cost).

Why it matters

Search traffic is different from social traffic. A person scrolling Instagram was not looking for you. A person who types "linen apron for pottery" wants one now. That intent is why a click from Google converts more often than a click from a feed, and why it costs more.

Here is the arithmetic that decides everything. Say your average order is $48 and your gross margin is 55%, so each order leaves $26.40 before ad costs. Your product page converts paid search traffic at 2.5%. That means you need 40 clicks per sale. If a click costs $0.60, one sale costs $24 in ads and you keep $2.40. If a click costs $0.80, the same sale costs $32 and you lose $5.60 on every order.

Nothing else about the campaign matters until that equation is positive. Google Ads matters because it exposes this math with brutal clarity. You see your cost per click, your conversion rate and your revenue per campaign in one table. Few channels give a small seller that much feedback that fast.

How it works

The auction runs every time a query is typed. Here is what happens in the half second before the results page loads:

  • You pick keywords. For a search campaign, you list the queries you want. "ceramic mug handmade" in phrase match will catch "handmade ceramic mug set" and "best handmade ceramic mug".
  • You write ads. A responsive search ad takes up to 15 headlines and 4 descriptions. Google assembles combinations and learns which ones people click.
  • You set a landing page. The URL the click goes to. For a store this should be the exact product or collection, not the home page.
  • You set a budget and a bid strategy. A daily budget caps spend (Google may spend up to twice it on a given day but averages out over the month). The bid strategy tells Google how to compete: manual CPC, maximize clicks, maximize conversions or target ROAS.
  • Google ranks the ad. Ad Rank is roughly your bid multiplied by your Quality Score, plus the expected impact of extensions. A relevant ad with a great page can beat a bigger bid.
  • You pay per click. You pay just enough to beat the advertiser ranked below you, not your full maximum bid.
  • A conversion tag reports back. A small script on your order confirmation page tells Google which clicks became sales, and for how much. Without it, automated bidding is blind.

For Shopping and Performance Max, keywords are replaced by your product feed: title, price, image, availability. Google matches queries to products on its own.

Benchmarks and examples

Costs vary wildly by industry, country and season, so treat these as orders of magnitude, not targets.

  • Cost per click on Search: $0.30 to $1.50 for most physical goods in the US and Europe. Niche crafts sit low; insurance, legal and software sit at $5 to $50, but those are not your market.
  • Cost per click on Shopping: often 30% to 50% lower than Search for the same product, because the tile already shows the price and filters out window shoppers.
  • Conversion rate from paid search: 2% to 4% for a store with a decent product page. Brand-name searches (people typing your store name) can convert at 8% to 15%.
  • ROAS: a store with 50% margins needs a ROAS above 2.0 just to break even on the ad, and above 3.0 to make it worth the time.

Three typical situations:

A creator selling a $79 video course runs Search ads on "learn watercolor online". Clicks cost $1.10. The sales page converts cold traffic at 1.5%, so a sale costs $73. That barely covers the price. The creator moves to a free lesson as a lead magnet, captures the email and sells over the following two weeks. Cost per email drops to $9 and 20% of those emails buy within a month, so a sale now costs $45.

A small skincare brand with a $34 average order tries Performance Max with $20 a day. Month one returns a ROAS of 1.4, month two 2.6 after the feed gets better titles and the low-margin travel sizes are excluded. Month three stabilizes at 3.1.

A candle maker bids on her own brand name. Clicks cost $0.12, conversion is 11%, and the campaign runs at a ROAS of 25. Tiny volume, but it blocks competitors from sitting above her on her own name.

Common mistakes

  • Sending clicks to the home page. Someone searching for a specific product should land on that product. Every extra click before the buy button costs you a share of the traffic you just paid for.
  • Broad match with no negative keywords. "mug" in broad match will show your ad on "mug shot", "mug cake recipe" and "mugging statistics". Check the search terms report weekly and add negatives.
  • Judging a campaign after three days. Automated bidding needs 30 to 50 conversions to learn. With $10 a day, that is a month. Decide on 30-day windows.
  • No conversion tracking. If Google does not know which clicks turn into sales, it optimizes for clicks. You will get cheap traffic that does not buy.
  • Ignoring margin. A ROAS of 2.5 sounds fine until you remember your margin is 35%. Set the target ROAS from your margin, not from a blog post.

Best practices

  • Start with brand and a tight product set. Bid on your own name first (cheap, high intent), then on 5 to 10 exact product queries. Widen only when those are profitable.
  • Match the ad to the page. If the ad says "linen apron, free shipping over $50", the page should show the apron and the shipping rule above the fold.
  • Feed your best products only. A Shopping feed with your 10 best sellers will usually outperform one with all 80 products, because the budget concentrates where conversion is proven.
  • Use a campaign-specific discount code. A code like SEARCH10 in the ad copy lets you see the campaign in your orders even when tracking breaks, and it lifts click-through.
  • Set a weekly review ritual. Fifteen minutes: search terms, cost per conversion, products with spend but no sales. Pause the losers, raise budgets on the winners by 20% at most.
  • Watch the landing page speed. A page that loads in 4 seconds on mobile can lose a third of paid clicks before they see anything. Compress images, remove pop-ups on paid landing pages.
  • Build a remarketing list from day one. Even if you do not run remarketing yet, the audience of past visitors accumulates and becomes your cheapest campaign later.

In Roctify

Roctify is not an ad platform, but it is where your ads land and where the money shows up. Every product page and your link-in-bio page can be used as a landing page, with one-page checkout, custom domain and free SSL so the click goes straight to a fast, trusted page. Discount codes let you tag each campaign (SEARCH10, SHOP15) and see which orders it produced. Because there is one shared catalog behind the store and the link-in-bio page, prices, stock and variants stay identical on every page you advertise, and the reports show orders and revenue per period so you can put real revenue next to your Google Ads spend and compute ROAS honestly. On the Pro plan, audience analytics and exports make that reconciliation easier.

FAQ

How much should I budget to test Google Ads?

Enough to buy at least 200 clicks, which is the minimum to see a conversion rate with any confidence. At $0.70 a click, that is $140. Spread it over two to four weeks rather than one day, so the auction and your ad variants have time to settle. If the test yields fewer than 3 sales, do not scale, fix the page or the offer first.

Is Google Ads or Meta Ads better for a small store?

Google catches demand that already exists; Meta Ads creates demand for something people were not searching for. If your product answers a query people type (a spare part, a specific style, a clear category), start with Google. If your product is new, visual and impulse-driven, start with Meta. Many stores end up running both, with Google taking the buyers Meta warmed up.

Do I need an agency to run Google Ads?

Not below $2,000 a month. A single Search campaign on brand and product keywords plus one Shopping campaign is manageable in an hour a week once set up. Agencies earn their fee when the account has dozens of campaigns, several countries or complex feeds. Learn the basics yourself first; you will manage the agency far better later.
