A

A/B testCreatives & testing

Running two versions of an ad that differ in just one thing, like the image or the hook, to see which wins.

Why it matters: Change one thing at a time, or you won’t know what made the difference.
In Adwize: Adwize splits your budget to test and tells you when a test has enough data to call.

AdCampaigns & budget

The bottom level: the creative, copy, headline and button people actually see.

Why it matters: The ad is what you can change most freely. It’s usually the fastest lever on your results.
In Adwize: Adwize writes on-brand ads from your Brand DNA, ready for you to review before anything goes live.

Ad accountTracking & account

Where your campaigns, billing and spending limits live. One business can hold several.

Why it matters: Agencies and freelancers run one per client, so budgets and data never mix.
In Adwize: Connect 1 account on Starter, 5 on Growth, up to 15 on Elite. Client data never mixes.

Ad copyCreatives & testing

The words around your creative: primary text above it, headline and description below.

Why it matters: Clear copy that names the benefit beats clever copy. Most people only read the first line.
In Adwize: Adwize writes copy in your brand voice. You edit anything before it goes live.

Ad reviewTracking & account

Meta checks every ad against its advertising standards before it runs, usually within a day.

Why it matters: Rejected ads delay launches, and repeated rejections can restrict your account.
In Adwize: You review every ad before it goes to Meta, so you can catch risky claims first.

Ad setCampaigns & budget

The middle level of a campaign. It sets the audience, placements, schedule and, with ABO, the budget.

Why it matters: Too many ad sets split your budget thin and keep each one stuck in the learning phase.
In Adwize: Adwize splits your budget across a few audiences to test, and tells you when a test has enough data.

Advantage+Campaigns & budget

Meta’s automation features: they let the algorithm widen your audience, choose placements or tweak creatives for you.

Why it matters: They often beat manual setups, especially with a working pixel and enough budget.
In Adwize: Adwize tells you which automation settings a campaign uses, and why, before you approve.

Attribution windowMetrics

The time frame Meta uses to credit a sale to your ad, like 7 days after a click or 1 day after a view.

Why it matters: Change the window and the same campaign looks better or worse. Compare numbers on the same window only.
In Adwize: Adwize’s numbers come straight from Meta, so they match what you see in Ads Manager.

Audience overlapAudiences

When two of your ad sets target many of the same people.

Why it matters: Your own ad sets end up bidding against each other, which raises costs.
In Adwize: Ask Adwize to review your account. It points out ad sets fighting over the same people.

B

Bid strategyCampaigns & budget

How Meta bids in the ad auction for you. “Highest volume” gets the most results for your budget; cost and bid caps add a limit.

Why it matters: Start with highest volume. Add a cap only once you know what a result is worth to you.
In Adwize: Adwize sets the bid strategy with the rest of the campaign and explains it before you approve.

Broad targetingAudiences

Targeting with just a location, age range and few or no interests, so the algorithm finds buyers itself.

Why it matters: It wins more often than you’d think, because your creative does the targeting.
In Adwize: Adwize picks the audience from your offer and tells you why. Change it before you approve.

Budget: CBO vs ABOCampaigns & budget

CBO sets one budget at the campaign level and lets Meta split it across ad sets (Meta now calls it Advantage+ campaign budget). ABO sets a fixed budget on each ad set.

Why it matters: CBO is simpler and lets the algorithm move money to what works. ABO gives you control when testing.
In Adwize: Your daily budget is never exceeded without you, and budget changes come in gradual steps.

Business ManagerTracking & account

Meta’s hub for your business assets: ad accounts, Pages, pixels and who has access. Meta now calls it a business portfolio.

Why it matters: Owning your assets here, not in a freelancer’s personal account, keeps you in control.
In Adwize: Connect Adwize in one click through Meta’s official login. Remove access anytime.

C

Call to action (CTA)Creatives & testing

The button on your ad, like Shop now, Sign up or Learn more, plus the action your copy asks for.

Why it matters: Match it to the step people are ready for. “Shop now” on a cold audience can feel pushy.
In Adwize: Adwize sets the button with the rest of the ad. Change it before you approve.

CampaignCampaigns & budget

The top level of a Meta ad setup. It holds your objective and, often, your budget. Ad sets and ads live inside it.

Why it matters: Fewer, simpler campaigns give Meta more data per campaign, which usually means better results.
In Adwize: Describe what you sell in one prompt and Adwize builds the full campaign in about 2 minutes, paused until you approve.

Campaign objectiveCampaigns & budget

The goal you give Meta: sales, leads, traffic, awareness, engagement or app promotion. Meta shows your ad to people likely to do that.

Why it matters: Same ads, different objective, different people and a very different cost. Pick the one closest to revenue.
In Adwize: Adwize sets the objective from what you describe and tells you why. Change it before you approve.

Catalog (dynamic ads)Campaigns & budget

Your product list, synced to Meta, so each shopper sees the products that fit them.

Why it matters: For stores with many products, it’s the fastest way to show the right item to the right person.
In Adwize: Adwize doesn’t manage catalogs. Give it a product or collection and it builds the campaign around it.

Conversion eventTracking & account

The action you tell Meta to optimize for, like Purchase, Lead or Add to cart.

Why it matters: Pick the event closest to revenue that still happens often enough, or the campaign never exits learning.
In Adwize: Adwize picks the goal from what you describe and tells you why, before you approve.

Conversion rateMetrics

The share of people who take your goal action (buy, sign up) after clicking your ad.

Why it matters: A good ad with a low conversion rate points to the landing page or offer, not the ad.
In Adwize: Ask Adwize why sales are down. It tells you if the issue is the ad or what happens after the click.

Conversions API (CAPI)Tracking & account

Sends conversion data from your server straight to Meta, alongside the pixel.

Why it matters: Browsers and ad blockers make the pixel miss sales. CAPI fills the gaps, so Meta optimizes on better data.
In Adwize: Better data means sharper suggestions. Most store platforms let you turn CAPI on in a few clicks.

Cost capCampaigns & budget

A bid setting that asks Meta to keep your average cost per result near a target.

Why it matters: It protects your CPA, but set it too low and your ads barely spend.
In Adwize: If a capped ad set stops spending, daily fixes point it out with a fix you approve in one click.

Cost per resultMetrics

Meta’s name for what you pay per goal reached. The “result” depends on your campaign objective: a purchase, a lead, a click.

Why it matters: It’s the most honest single number in Ads Manager, as long as the result is the one you care about.
In Adwize: Daily fixes flag any ad above your target cost, with a fix you apply in one click.

CPA (cost per acquisition)Metrics

What each purchase or sign-up from your ads costs on average: spend divided by conversions.

Why it matters: It’s the number that decides if you can scale. If your CPA is below what a customer is worth, spend more.
In Adwize: Set a rule like “alert me if cost per sale goes over $40.” Adwize checks it 24/7.

CPC (cost per click)Metrics

What each click on your ad costs: spend divided by clicks.

Why it matters: A rising CPC often means your ad is losing attention. But cheap clicks don’t matter if nobody buys.
In Adwize: Adwize reads CPC next to CTR and CPA, so you don’t chase clicks that don’t convert.

CPL (cost per lead)Metrics

What each lead costs you: spend divided by leads (form fills, calls, sign-ups).

Why it matters: The key number for service businesses. A cheap lead that never buys is still expensive, so track quality too.
In Adwize: Adwize reports CPL per ad set, so you see which audience brings leads at the right price.

CPM (cost per 1,000 impressions)Metrics

What you pay for 1,000 views of your ad.

Why it matters: It measures what your audience costs, not how well your ad works. A cheap CPM with a weak ad is still a bad campaign.
In Adwize: Ask why costs went up and Adwize answers in plain English, from your own account data.

CreativeCreatives & testing

The visual part of your ad: image, video or carousel. A variant changes one thing from a winning creative.

Why it matters: On Meta today, the creative does most of the targeting. More good creatives, more good results.
In Adwize: Adwize makes on-brand creatives from your Brand DNA: your colors, fonts and tone, every time.

Creative fatigueCreatives & testing

When people have seen your ad too often and stop reacting: CTR falls and cost per result rises.

Why it matters: Every ad wears out. Catch it early and swap in a fresh variant before costs climb.
In Adwize: You get a heads-up before costs climb, with fresh versions ready to approve.

CTR (click-through rate)Metrics

The share of people who click after seeing your ad: clicks divided by impressions.

Why it matters: A quick read on whether your hook works. Always check it against CPA before you crown a winner.
In Adwize: When CTR drops while frequency climbs, Adwize flags creative fatigue and suggests a fresh variant.

Custom audienceAudiences

An audience built from people who already know you: site visitors, customer lists, video viewers, followers.

Why it matters: It’s the base for retargeting, lookalikes and exclusions, like not showing ads to people who just bought.
In Adwize: Ask Adwize for a retargeting campaign and it builds it for you, paused until you approve.

D

Daily vs lifetime budgetCampaigns & budget

A daily budget is the average you spend per day. A lifetime budget is a total spread across a set end date.

Why it matters: Meta can spend a bit more on good days and less on slow ones. Daily is easier to control for always-on ads.
In Adwize: Set your daily budget in one sentence. A rule can alert you if it’s spent too fast.

F

FrequencyMetrics

The average number of times one person has seen your ad.

Why it matters: When frequency rises and results drop, people are tired of your ad. It’s the earliest sign to refresh it.
In Adwize: Adwize tracks frequency around the clock and tells you when an ad needs a new creative.

H

HookCreatives & testing

The first line or first seconds of your ad, the part that stops the scroll.

Why it matters: If the hook fails, nothing else gets seen. It’s the cheapest thing to test.
In Adwize: From your offer and website, Adwize suggests hooks and visuals. Keep the ones that fit.

I

ImpressionsMetrics

The total number of times your ad was shown, counting repeat views by the same person.

Why it matters: It’s the base for CPM and CTR. On its own, it says nothing about sales.
In Adwize: Adwize uses impressions to calculate the rates that matter, then tells you what they mean.

Instant formCampaigns & budget

A lead form that opens inside Facebook or Instagram, so people sign up without leaving the app.

Why it matters: Less friction means more leads, but often lower quality. Add a question or two to filter.
In Adwize: Ask for leads in your prompt. Adwize builds the campaign, and you review everything before launch.

L

Learning phaseCampaigns & budget

The period when Meta figures out who to show your ad to. It exits after about 50 results in a week.

Why it matters: Results swing while it learns, and big edits restart it. Hold off on changes for a few days.
In Adwize: Adwize suggests budget changes in gradual steps, so your campaigns don’t restart learning for nothing.

Lookalike audienceAudiences

An audience Meta builds to resemble a source you give it, like your buyers or top customers.

Why it matters: Only as good as its source. It needs a real list of buyers, usually a few hundred at least.
In Adwize: Ask Adwize if a lookalike makes sense yet. It reads your account and gives you a straight answer.

M

Meta PixelTracking & account

A small piece of code on your website that tells Meta when someone visits, adds to cart or buys.

Why it matters: Without it, Meta can’t tell which ads drive sales, and it can’t optimize for them.
In Adwize: Adwize works from the results your pixel reports, so a working pixel is the first thing to check.

P

PlacementsCampaigns & budget

Where your ad shows: Facebook and Instagram feeds, Stories, Reels, Messenger, Audience Network and more.

Why it matters: Letting Meta choose placements usually lowers cost. Each placement needs the right format, like vertical video for Reels.
In Adwize: Each ad is sized for feeds, Stories and Reels across Facebook, Instagram, Messenger and more.

R

ReachMetrics

The number of unique people who saw your ad at least once.

Why it matters: Reach shows how far your budget travels. Flat reach with rising spend means you’re showing the same people again.
In Adwize: Your report puts reach next to frequency, so you see at a glance if you’re growing or repeating.

RetargetingAudiences

Showing ads again to people who already interacted with you: site visitors, cart abandoners, followers.

Why it matters: Warm audiences convert cheaply, but they’re small. Keep retargeting a slice of the budget, not the bulk.
In Adwize: Set a rule and Adwize alerts you when a warm audience starts seeing your ads too often.

ROAS (return on ad spend)Metrics

Revenue earned for every dollar spent on ads: revenue divided by spend. A ROAS of 3 means $3 in sales for every $1 in ads.

Why it matters: It tells you if your ads pay for themselves. Know your break-even ROAS before you judge a campaign.
In Adwize: Ask for a report anytime. You get ROAS per campaign, straight from Meta, with the one thing to do next.

S

ScalingCampaigns & budget

Growing spend on what works, either by raising budgets or by adding new campaigns.

Why it matters: Raise too fast and costs jump. Steady steps usually keep results stable.
In Adwize: Adwize suggests budget increases in steps, one click to approve each.

Special Ad CategoryTracking & account

Meta’s restricted categories: housing, financial products and services, employment, and social issues, elections or politics. Targeting is limited, with no age or gender options.

Why it matters: If your ad fits one, you must declare it, or risk rejected ads and account restrictions.
In Adwize: Mention it in your prompt. You review the targeting before anything goes live.
