How to Improve PPC Campaign Performance in Google Ads: A Step-by-Step Workflow

Most Google Ads accounts that feel stuck have the same problem: money is going to searches that were never going to convert, while the searches that do convert are under-bid or buried. This guide gives you a repeatable routine to improve PPC campaign performance in a Google Ads Search campaign, moving from measurement to cleanup to expansion to tuning. You'll need account access, at least a few weeks of click data, and a clear conversion goal.

Step 1: Confirm Conversion Tracking and Set a Baseline

Every optimization you make will be judged against your conversion data, so start by checking what your account counts as a conversion. Open your conversion actions and make sure the ones marked as primary reflect real business value: purchases, qualified leads, booked calls. If page views or button clicks sit alongside them as primary actions, bidding and reporting will reward the wrong behavior, and every later step will chase a bad signal.

Next, record a baseline for a fixed date range, such as the last 30 days, before you change anything. Capture:

• Spend
• Conversions
• Cost per conversion (CPA) or return on ad spend (ROAS)
• Conversion rate
• Search impression share (the share of eligible impressions you actually received)

Keep a simple change log next to it. This is an illustrative layout:

• Baseline (last 30 days): spend, conversions, CPA, conversion rate, impression share
• Change log: date, what changed, why you changed it

The log matters more than it looks. Three weeks from now, you'll want to know which change moved CPA, and memory won't be good enough.

One mistake to avoid is judging changes on too little data. Google's guidance says Smart Bidding learns from your conversion history, so very low conversion volume makes results noisy and harder to read. Check the current wording in Google Ads Help for bidding strategy requirements. If you only get a handful of conversions a month, give changes more time and lean on cleanup work rather than aggressive bidding experiments.

Step 2: Audit the Search Terms Report for Wasted Spend

The search terms report shows what people actually typed before seeing your ad. That's different from your keywords, which are what you bid on. A single keyword can trigger dozens of different search terms, and some of them will be nowhere near what you intended.

In Google Ads, you'll find the report under Insights and reports, then Search terms. Google moves menus around occasionally, so confirm the path in your own account if it looks different. Set the date range to match your baseline so the numbers line up.

Then work it in two passes:

1. Sort by cost and look for terms with spend and zero conversions. The biggest leaks go first.
2. Sort by conversions to find your winners. Note them for Step 4.

Read the terms, don't just glance at the numbers. A term with two clicks and no conversions might be perfectly relevant, while one with a single click might be clearly the wrong audience. Intent is what you're evaluating.

One pitfall: the report doesn't show everything. Google hides some low-volume queries for privacy reasons, so the list you see is incomplete. Don't assume you've found every problem; the Google Ads Help page on the search terms report explains what's shown and what isn't.

This is the part of the job that eats hours when you export to a spreadsheet, filter, and re-upload. Keywordme is a Chrome extension that works inside the Search Terms Report itself, so you can review and tag terms in the same screen without exporting anything. You still make each call yourself; the extension just removes the busywork.

Step 3: Add Negative Keywords to Block Irrelevant Traffic

A negative keyword tells Google not to show your ad for searches containing that term. A positive keyword is what you want to match; a negative is what you want to avoid. Negatives are the fastest way to cut wasted spend, but only if you choose them with care.

The decision rule: add a negative when the intent is wrong, not just because a term hasn't converted yet. Suppose you sell a paid accounting service. Terms containing "free," "jobs," or "DIY" signal people who won't buy, so they're sensible negative candidates (illustrative examples). A relevant term with two clicks and no sales is just a small sample and needs more data.

Pick the match type and level

Negative match types behave differently from positive ones. Negative broad, phrase, and exact each have their own rules, and negatives don't expand to close variants such as plurals or misspellings the way positive keywords can. If you block "job," you may still see "jobs" unless you add it too. Check Google Ads Help for the current behavior before building a big list.

Then choose where the negative lives:

• Ad group: for terms that are wrong for one ad group but fine elsewhere.
• Campaign: for terms that are wrong across the whole campaign.
• Shared negative keyword list: for account-wide junk you want applied to multiple campaigns.

The mistake to avoid is blocking your own good traffic. Before you add a negative, cross-check it against your keyword list. A broad negative like "cheap" can quietly kill a keyword you actually bid on.

With Keywordme, you can add a negative in one click from the Search Terms Report, pick the match type as you go, and build reusable lists. You review each choice before it's applied.

Step 4: Promote High-Intent Search Terms to Keywords

Cleanup stops the leaks. Expansion is where you start scaling. Go back to the winners you noted in Step 2 and decide which deserve to become keywords in their own right.

A term is worth promoting when it converts, or when it shows clear buying intent at a sensible cost and keeps appearing. A one-off query isn't a pattern. Repetition is.

Choose the match type on purpose

Exact match suits proven terms where you want tight control. Phrase match lets you expand in a controlled way around a theme. Broad match reaches the furthest, and Google's guidance has been that it works best paired with Smart Bidding and solid conversion data. Confirm the current recommendation in Google Ads Help before leaning on it, especially if your conversion volume is thin.

Put each keyword where it belongs

Add each new keyword to the ad group whose ad copy and landing page match it. A term about "emergency plumber" belongs with emergency messaging, not a general plumbing ad group (illustrative). Also avoid duplicating the same keyword across ad groups, since they'll compete with each other and muddy your data.

If you have several close variants of one idea, group them into a tightly themed ad group instead of dumping everything into one bucket. Tight themes make it easier to write relevant ads and to read performance later.

Keywordme lets you add terms as keywords with your chosen match type straight from the Search Terms Report, and its keyword clustering helps group related terms together, all without leaving Google Ads. Check each placement before you confirm it.

Step 5: Align Ads and Landing Pages with Search Intent

Better keywords only help if the ad and page behind them deliver. Take your top converting search terms and compare them with your current headlines and descriptions. Where it's accurate, work the language of real queries into your responsive search ad assets. People click ads that echo what they typed.

Then click through to the landing page as if you were the searcher. Does the page deliver on the promise of the search term? Check for message match and a single, clear call to action. A visitor who searched for a specific service and lands on a generic homepage will often leave, however good the ad was.

Quality Score is worth a look here, but treat it correctly. Google describes it as a diagnostic tool, not a KPI. Its components (expected CTR, ad relevance, and landing page experience) can point you toward what's weak. If landing page experience is flagged below average for a high-spend keyword, that's a lead to investigate. Chasing a 10 out of 10 for its own sake is not the goal; conversions at a good cost are.

Ad strength works the same way. It's guidance on how complete and varied your responsive search ad is, not proof it will perform. An "Excellent" rating doesn't guarantee more conversions.

Test one change at a time and log it in the change log from Step 1. If you rewrite headlines, swap the landing page, and add a new offer in the same week, you won't know which one helped. Slow and attributable beats fast and ambiguous.

Step 6: Tune Bids, Budgets, and Targeting

Only now do you touch bids. That order is deliberate: tuning bids on top of junk traffic just pays more efficiently for the wrong clicks.

Match your bid strategy to the data you have. Manual bidding or maximize clicks can make sense while data is thin. Target CPA or target ROAS works better once conversion volume supports it. Google sets its own guidance on how much conversion history these strategies need, and it can change, so check Google Ads Help for the current requirements.

For budgets, look at each campaign's status. If one is limited by budget and has a good CPA, it's a candidate for more spend. If another has a poor CPA, move some budget from it rather than adding new money everywhere. Bigger budgets don't fix a campaign with a conversion problem.

Then review the segments that often hide waste:

• Device: does mobile convert much worse than desktop?
• Location: are certain regions spending without returning?
• Ad schedule: are there hours or days with clicks but no conversions?

Apply bid adjustments or exclusions only where the data shows a clear gap. A small sample with a big swing is usually noise.

The pitfall to avoid is changing bid strategy and budget in the same week. You won't be able to separate cause from effect, and a bid strategy change can restart the learning period. Change one, log it, wait, then move to the next.

Step 7: Set a Weekly Optimization Routine and Measure Results

One-off cleanups fade. Negatives aren't a one-time job, because new search terms keep arriving. A schedule keeps the gains. An illustrative cadence:

• Weekly: review the search terms report, add negatives, promote winners.
• Monthly: review ads and landing pages.
• Quarterly: review account structure and bidding strategy.

To measure progress, compare against the Step 1 baseline over a matching date range, such as 30 days against the 30 days before. Judge on conversions and CPA or ROAS, not clicks alone. More clicks at a worse cost per conversion is a step backward.

Give changes room before calling them failures. Conversions can be reported with a delay, so recent days may look worse than they are. Bid strategy changes also need time to learn. Check Google Ads Help for how conversion delays and learning periods work for your setup.

If you run several accounts as a freelancer or agency, standardize this routine so every client gets the same checks at the same intervals. Keywordme offers multi-account and team support, which fits that kind of workflow; confirm the current details on keywordme.io before you plan around specifics.

Keep the Gains: What to Do After Your First Cycle

After a few weeks, recheck your baseline numbers. Keep the changes that moved cost per conversion in the right direction, undo the ones that didn't, and note both in your log. Then repeat the search terms routine on schedule, because that's where most of the steady gains come from.
