PPC Strategy: How to Plan Google Ads That Pay Back

A PPC strategy is the written plan behind your paid search: the business goal, the profit you can afford per lead or sale, which searches you will pay for, how Google Ads should bid, how much you will spend and how you will measure results. Without it, campaigns tend to drift towards whatever the platform suggests, and spend grows faster than enquiries.

This guide sets out how we build a PPC strategy for UK businesses at ProntX, using Google’s own Google Ads documentation as of October 2026. It includes a worked break-even example, a bid strategy table and a checklist you can use on your own account.

Key takeaways

• Start with the numbers: decide the most you can pay for a lead or sale before choosing keywords or bids.
• Match the bid strategy to the goal. Google’s conversion-based strategies only work if conversion tracking is set up correctly.
• Broad match and Smart Bidding are designed to work together, but negative keywords and clean data keep them honest.
• A daily budget is an average. Google can spend up to twice it on a single day, but no more than 30.4 times it across a month.
• UK tracking needs consent mode in place, and paid search ads must follow the CAP Code like any other advert.

What is a PPC strategy, and how is it different from PPC tactics?

A PPC strategy is the overall plan that decides what your paid search is for and how success is judged; tactics are the individual settings and changes used to carry it out. Choosing Target CPA bidding, adding a negative keyword or rewriting a headline are tactics. Deciding that the account exists to win quote requests below a set cost is strategy.

The difference matters because Google Ads is full of recommendations. Many are reasonable, but each one is written to improve a platform metric, not your profit. A clear strategy gives you a reason to accept or reject each suggestion. It also stops the common pattern where a business adds campaigns one at a time until nobody can explain what the account is meant to achieve.

What should a PPC strategy include?

A complete PPC strategy covers seven decisions, made in this order, because each one depends on the one before it.

1. The business goal. Sales, booked calls, quote requests or sign-ups. Pick one main conversion per campaign and treat everything else as secondary.
2. The target cost. The highest cost per lead or sale you can pay and still make money, plus a lower cost you would be happy with.
3. The audience and the searches. Which problems, products and locations you want to appear for, and which searches you never want to pay for.
4. The campaign types. Search for people actively looking, Performance Max or Shopping for product catalogues, and video or display only when there is a reason.
5. The bid strategy. Clicks, conversions, conversion value or visibility, chosen to match the goal and the amount of data you have.
6. The budget. A monthly figure that can buy enough clicks to learn something, split across campaigns by priority.
7. Measurement and review. What gets tracked, where it is reported and how often decisions are made.

If you only have time for two of these, do the first two properly. A tidy account with the wrong target cost will still lose money.

How do you work out what you can afford to pay per lead?

Work backwards from profit: take the profit from one customer, multiply it by the share of leads that become customers, and the result is your break-even cost per lead. Anything below that figure is profitable; anything above it is a loss, however good the click-through rate looks.

Here is an illustrative example for a service business. These figures are made up to show the method, not results from any account.

• Average job value: £1,200
• Gross profit after materials and labour: £400
• Share of enquiries that become paying jobs: 25%
• Break-even cost per enquiry: £400 x 25% = £100

At £100 per enquiry the business only breaks even on the first job, so a sensible target might be £60 to £70, leaving room for the management fee and for weeks when conversion rates dip. If a customer usually comes back, you can justify a higher target, but only if you can show the repeat business in your own records. For ecommerce, the same logic gives you a target return on ad spend (ROAS) instead of a cost per lead.

Which Google Ads bid strategy should you choose?

Choose the bid strategy that matches what you want more of: clicks, conversions, conversion value or visibility. Google groups its bid strategies by these goals, and it states that for the conversion-based options you should make sure your conversion tracking is set up correctly before you rely on them.

Google also notes that Maximise clicks is not suited to campaigns that need a specific cost per conversion, which is why we treat it as a starting point rather than a long-term setting. A typical path is to begin on clicks or Maximise conversions, then move to Target CPA or Target ROAS once the campaign has a steady record of conversions to learn from.

How should keywords and match types fit the strategy?

Keywords decide which searches you can appear for, and match types decide how loosely Google interprets them. Google describes three positive match types:

• Broad match (no symbols) may show your ad on searches related to your keyword. It is the default and reaches the most searches.
• Phrase match (“keyword in quotes”) may show your ad on searches that include the meaning of your keyword.
• Exact match ([keyword in brackets]) may show your ad on searches with the same meaning or intent. It gives the most control and reaches the fewest searches.

Google’s guidance says Smart Bidding works best with broad match, because bids are set for each search using signals available at auction time. In practice we only lean on broad match once conversion tracking is trustworthy and the target cost is set. Before that, phrase and exact match keep spend close to the searches you meant to buy.

Negative keywords are the other half of keyword strategy. They stop your ads showing on searches containing a term, such as “free”, “jobs” or a product you do not sell. Google points out that negative match types behave differently from positive ones, so read the search terms report every week in the early months and add negatives from what people actually typed.

How much budget does a PPC strategy need?

A PPC budget needs to buy enough clicks for the campaign to produce conversions you can learn from; a budget too small to generate a handful of leads a month will not tell you whether the strategy works. Start from your target cost per lead and the number of leads you want, then check that the result is realistic against the click prices Keyword Planner shows for your terms.

Two Google rules matter when you plan cash flow. Google says a campaign “might spend up to twice your average daily budget” on a given day to take advantage of traffic swings, and that across a month you will spend no more than 30.4 times your average daily budget. So a £50 daily budget means roughly £1,520 a month, not £50 every day.

Ad spend and management are separate costs. At ProntX, paid search management starts from £450 a month on a rolling monthly contract, and ad spend is paid direct to Google from your own account, so you always see exactly what the clicks cost.

Where does Performance Max fit in a PPC strategy?

Performance Max is a goal-based campaign type that can serve ads across all Google Ads inventory from one campaign, including Search, YouTube, Display, Discover, Gmail and Maps. Google recommends it when you have specific conversion goals such as online sales or leads, and describes it as a way to complement keyword-based Search campaigns.

It suits ecommerce businesses with a product feed and service businesses with plenty of conversion data. It is a poorer fit when tracking is weak, because the campaign optimises towards whatever it is told is a conversion. Google also states that when a search matches an exact match keyword in a Search campaign, that Search campaign takes priority over Performance Max, which is useful when you want tight control over your most valuable terms.

What tracking does a UK PPC strategy need?

A UK PPC strategy needs conversion tracking that records real business outcomes, consent mode connected to your cookie banner, and ideally enhanced conversions. Without these, every automated bid strategy in the account is learning from incomplete or wrong data.

• Conversion actions: track form submissions, calls and purchases as primary conversions. Page views and button clicks are better kept as secondary actions.
• Consent mode: Google describes consent mode as the way to pass your visitors’ cookie consent status to Google. It does not create a banner; it works with the one you already have. In advanced mode, tags still send cookieless pings when consent is denied, which supports more detailed conversion modelling than basic mode.
• Enhanced conversions: these send first-party data such as email addresses, hashed with the one-way SHA256 algorithm, to improve conversion measurement. There is a version for website sales and a version for leads that close offline.
• GA4 and Search Console: link them so you can compare paid and organic behaviour on the same landing pages.

Paid search ads are also adverts in the legal sense. The ASA’s advice states that pay per click and other sponsored search listings are covered by the CAP Code, so claims about prices, results or being “the best” need evidence. You can read it in the ASA guidance on search engines and price comparison sites.

How do you know if your PPC strategy is working?

Your PPC strategy is working when the cost per lead or ROAS sits inside your target and lead quality holds up when you check it against real sales. Click-through rate, Quality Score and impression share help explain results, but they are not results. Google itself describes Quality Score as a diagnostic tool that is not an input in the ad auction.

Use this decision framework at each monthly review:

1. Cost per lead below target and lead quality good: raise budget in small steps and watch whether cost holds.
2. Cost per lead below target but leads poor: fix what counts as a conversion, tighten keywords and qualify on the landing page before spending more.
3. Cost per lead above target with good leads: work on the landing page and offer first, then bids. Conversion rate is usually the quickest lever.
4. Cost per lead above target and leads poor: go back to the search terms report, match types and negatives. The account is likely buying the wrong searches.
5. Not enough conversions to judge: narrow the focus to fewer, higher-intent terms rather than spreading a small budget thinly.

PPC strategy checklist

• One main conversion per campaign, tracked and tested with a real form fill or purchase
• Break-even and target cost per lead (or target ROAS) written down
• Keyword list grouped by intent, with match types chosen on purpose
• Starter negative keyword list, reviewed weekly against search terms
• Bid strategy matched to the goal and the amount of conversion data
• Monthly budget planned using the 30.4 times daily budget rule
• Consent mode connected to your cookie banner; enhanced conversions considered
• Landing pages that match the ad, load quickly and make the next step obvious
• Ad copy claims you can back up under the CAP Code
• A monthly review date and the decision framework above

If your account already exists, a structured review of your current Google Ads setup is often the fastest way to see which of these points are missing. For the wider question of when paid search should take priority over organic, see our guide to choosing between SEO and PPC.
