Paid Ads Guide for SaaS Founders

Everything you need to launch, track, and optimise paid campaigns — from choosing the right platform to understanding your CPA.

What is Paid Advertising?

Paid advertising (also called PPC — Pay-Per-Click — or SEM — Search Engine Marketing) means paying a platform to show your message to a targeted audience. Unlike organic marketing where you earn visibility, paid ads rent attention and can generate results from day one.

You typically pay in one of three ways:

CPC

Cost Per Click

Pay only when someone clicks your ad. Common on Google Search, Meta.

CPM

Cost Per 1000 Impressions

Pay for visibility regardless of clicks. Common on display and video.

CPA

Cost Per Acquisition

Pay only when a conversion happens. Requires tracking setup.

Choose the platform that matches where your audience spends time and your budget constraints.

Key Metrics Explained

You'll see these metrics in your dashboard. Here's what each one means and what "good" looks like.

CTR — Click-Through Rate

Clicks ÷ Impressions × 100

The percentage of people who see your ad and click on it. A high CTR means your ad copy and targeting are well aligned. Low CTR suggests your headline or creative isn't resonating.

Good: Google Search ≥ 6%, Meta ≥ 0.9%, LinkedIn ≥ 0.5%

CPC — Cost Per Click

Total Spend ÷ Total Clicks

How much you pay on average every time someone clicks your ad. Lower is better, but a high CPC can still be profitable if your conversion rate is strong.

Good: Google Search ≤ $4.66, Meta ≤ $1.72, LinkedIn ≤ $7.00

CPM — Cost Per Mille

(Total Spend ÷ Impressions) × 1000

The cost to show your ad to 1,000 people. Key for awareness campaigns where you care about reach more than clicks. Lower CPM = more visibility for your budget.

Good: Meta ≤ $14.90, TikTok ≤ $9.16, Google Display ≤ $2.80

CVR — Conversion Rate

Conversions ÷ Clicks × 100

The percentage of ad clickers who complete your goal (purchase, sign-up, form fill). This depends heavily on your landing page quality, not just the ad itself.

Good: Meta ≥ 9.2%, Google Search ≥ 7%, LinkedIn ≥ 6% (lead gen form)

CPA — Cost Per Acquisition

Total Spend ÷ Total Conversions

How much you spend to get one customer or lead. The most important metric for profitability. Compare against your average order value or customer LTV to check viability.

Good: Meta ≤ $18.68, Google ≤ $66.17. Target CPA < 30% of LTV for SaaS

ROAS — Return on Ad Spend

Revenue from Ads ÷ Ad Spend

For every $1 spent on ads, how much revenue did you generate? A ROAS of 3× means $3 revenue per $1 spent. Essential for eCommerce where revenue is directly attributable.

Good: eCommerce ROAS ≥ 3–4×, SaaS varies (depends on CAC:LTV ratio)

Industry Benchmarks (2025–2026)

Use these numbers to set expectations and benchmark your campaign performance. All figures are platform-wide averages from 2025–2026 research reports.

Meta / Facebook Ads	2.59%	$1.92	$19.81	7.72%	$27.66
LinkedIn Ads	0.56%	$8.00	~$50	7.00%	$100+

Setting Up Your First Campaign (Step-by-Step)

Define your goal before touching the platform

Know your goal before you open any ad platform. Common goals:

Awareness — maximise impressions. Optimise for CPM.
Traffic — drive clicks to a page. Optimise for CPC/CTR.
Conversions — sign-ups, purchases. Optimise for CPA/ROAS.

Set your budget using the CPA formula

Work backwards from your economics:

Max CPA = Customer LTV × Target margin
Daily budget = (Target conversions/month ÷ 30) × Max CPA

Example: LTV $200, target 30% margin → Max CPA $60. Need 10 conversions/month → $20/day budget minimum.

Build your targeting audience

Narrow targeting gets cheaper clicks but smaller reach. Start broad, then refine based on data:

Google: use Broad Match keywords + Smart Bidding for discovery; Exact Match for control
Meta: start with interest + demographic targeting; then use Lookalike Audiences once you have 1,000+ conversions
LinkedIn: target by job title + company size for B2B; avoid too many layers (raises CPM)

Write high-converting ad copy

The formula that works consistently:

Headline: State the benefit or problem solved, not the feature
Body: Proof + urgency ("10,000 businesses use…", "Offer ends Friday")
CTA: Action verb + benefit ("Get Free Trial", "See Pricing")

Always test 2–3 variations (A/B test). Let each run for at least 50–100 clicks before judging.

Install conversion tracking before going live

Without conversion tracking you're flying blind. Set up:

Google Tag Manager + Google Ads conversion tag on thank-you page
Meta Pixel + Events (PageView, Lead, Purchase) on your site
UTM parameters on all ad URLs → use the UTM Links tab to track with MarketiStats

Log your daily spend in MarketiStats

After your campaign runs, come to the Ad Campaigns tab and add daily entries for spend, clicks, impressions, and conversions. This unlocks your CPC, CPA, and CTR charts — and lets you compare against benchmarks in the Simulator.

Budget Planning & Optimisation

💡

The 70/20/10 rule: Spend 70% of budget on proven campaigns, 20% on scale tests of winners, 10% on experiments. Don't bet everything on one ad.

ℹ️

Learning phase: Most ad platforms need 50 conversions per week to exit the learning phase and optimise bidding. Budget accordingly — underfunding kills performance.

⚠️

Don't optimise too early. Wait until each ad variation has received at least 50–100 clicks before pausing it. Statistical significance matters.

Start small

$20–50/day for 1–2 weeks to gather data before scaling

Day-part bids

Analyse by hour/day — many B2B ads perform 2× better Tuesday–Thursday 9am–6pm

Negative keywords

On Google: block irrelevant searches immediately. Saves 10–30% of wasted spend

Quality Score

On Google, a higher Quality Score reduces your CPC. Improve landing page relevance to cut costs

Frequency cap

On social: cap impressions per user at 3–5/week to avoid creative fatigue

Retargeting

Audiences who visited your site convert 3–5× better. Always run a retargeting campaign

Common Mistakes to Avoid

✗

Sending traffic to your homepage

Always send ad traffic to a dedicated, relevant landing page. Homepages convert at 1–2%; focused landing pages at 5–15%.

✗

No conversion tracking

If you can't measure CPA, you can't optimise. Set up tracking on day 1.

✗

Changing campaigns too frequently

The algorithm needs time to learn. Wait 7–14 days before making significant changes.

✗

Ignoring search terms report (Google)

Review your actual search terms weekly. Add negatives to stop wasted spend on irrelevant queries.

✗

Broad audience + no data

Without Pixel data or prior conversions, Meta's algorithm can't find buyers. Start with narrow, targeted audiences.

✗

Comparing platforms directly

A $50 CPA on LinkedIn for a $5,000 B2B contract is excellent. A $50 CPA on Meta for a $60 product isn't. Always evaluate relative to revenue.
