Digital marketing is full of acronyms and shorthand. You do not need to memorise them all, but knowing the common ones helps you read a report, question an agency and brief your own team with confidence.
This glossary explains the terms agents run into most often when they work on social media, advertising, websites and email. The entries are in alphabetical order, so you can jump to the one you need.
How to use this glossary
Skim the section on key measures first, since those numbers are the ones that show up in most campaign reports. Then use the alphabetical list as a reference when you meet a term you do not know.
The measures that matter most to an agent
Many metrics exist, but a short list is enough to judge most campaigns:
- Reach and impressions tell you how many people saw something.
- CTR tells you how many of them clicked.
- Conversion rate tells you how many of those completed the action you wanted.
- Cost per lead tells you what an enquiry cost.
Reach and clicks are easy to inflate. Leads and booked appraisals are what pay the bills, so judge campaigns by those first.
Social media and advertising terms
The entries below cover everything from algorithm to retargeting. Terms that relate to how you measure results, build a website or rank in search follow in the same list, to make the glossary easy to scan.
The glossary, A to Z
A/B testing
Also called split testing. You show two versions of an ad, email or page to similar audiences at the same time, changing one element only, to see which performs better. See our A/B testing guide for the full process.
Ads Manager
Meta's tool for creating, running and reporting on Facebook and Instagram ad campaigns. It is where you set budgets, audiences, placements and objectives, and where you read your results.
Algorithm
The set of rules a platform uses to decide what to show each person and in what order. Platforms change these rules often, so build your marketing on things that stay useful, such as clear messaging and good local content.
API
Short for application programming interface. It is how two pieces of software exchange information. When your CRM sends new contacts to your email platform automatically, an API connection is usually doing the work.
Audience
The group of people you reach or target. On social media it can mean your followers. In advertising it means the specific group you choose to show an ad to, based on location, interests or past behaviour.
Avatar
The small profile picture that represents you or your agency on a social network. Use a clear headshot or logo that is recognisable at a tiny size.
Bio
The short description on your social media profile. It should say who you help, where, and what to do next, usually with a link to your website.
Boosted post
An existing organic post that you pay to show to more people. It is quick to set up but offers fewer options than a campaign built in Ads Manager.
Business Manager
Meta's system for managing your business pages, ad accounts and team access in one place, so that your assets belong to the business and not to one person's personal profile.
Chatbot
An automated program that answers common questions in a messaging channel and can collect details or book appointments. It works best for simple, repeatable questions, such as open home times.
Clickbait
Headlines or images that exaggerate or withhold information to force a click. Platforms can reduce the reach of content that does this, and it damages trust with readers.
CMS (content management system)
Software that lets you create and edit website pages without writing code. WordPress is one of the best-known examples.
CRM (customer relationship management)
Software that stores your contacts, tracks conversations and schedules follow-up. For agents, it is where appraisal enquiries, vendors and buyers should be recorded, so no lead is forgotten.
CTA (call to action)
The instruction that tells someone what to do next, such as "Book a free appraisal". Every ad, email and page should have one clear CTA.
CTR (click-through rate)
The percentage of people who saw your ad or link and clicked it. Clicks divided by impressions, multiplied by 100. A high CTR shows the message got attention, but not that those clicks became leads.
Conversion
The action you want a person to take, such as submitting an appraisal form, calling, or downloading a guide. You decide what counts as a conversion, and it should be a step that is valuable to your business.
Conversion rate (CVR)
The percentage of visitors or ad viewers who complete a conversion. It is a better measure of quality than clicks alone.
CPC (cost per click)
What you pay on average for each click on an ad. Total spend divided by clicks. A cheap click is not automatically a good result, and a more expensive click can be worth it if it converts.
CPL (cost per lead)
Total ad spend divided by the number of leads generated. It is a more useful figure for agents than CPC, as it measures what you pay for an enquiry.
DM (direct message)
A private message sent through a social platform.
Engagement rate
The share of people who interacted with a post, usually through likes, comments, shares, saves or clicks, divided by those who saw it. Platforms define engagement slightly differently, so compare like with like.
Evergreen content
Content that stays useful long after you publish it, such as a guide to preparing a home for sale, as opposed to news about a platform update. It can be reshared repeatedly.
Feed
The stream of posts you see when you open a social platform.
Geotargeting
Showing ads only to people in selected locations, such as particular suburbs or a radius around a listing. It is central to local real estate advertising.
GA4 (Google Analytics 4)
Google's current analytics product for measuring how people use your website and apps. It reports on events, such as form submissions and phone clicks. See our Google Analytics guide for real estate.
Google Business Profile
Your free listing on Google Search and Maps, which shows your agency's address, hours, reviews and photos. It was previously called Google My Business.
Impressions
The number of times your content was displayed. One person seeing an ad four times counts as four impressions.
KPI (key performance indicator)
A number you track to see if you are on target, such as booked appraisals per month or cost per lead.
Landing page
A page built for one purpose and one audience, usually the page an ad or email sends people to. It has a single CTA, such as a form for an appraisal.
Lead
A person who has shown interest in your service and given you their contact details, such as a vendor who requested an appraisal.
Lead magnet
A free resource offered in exchange for contact details, such as a suburb report or a selling checklist.
Listicle
An article built around a numbered list, such as "7 ways to prepare for an auction".
Lookalike audience
An ad audience built by the platform from people who resemble a source group, such as your existing contacts or past leads.
Metric
Any measurable number used to track performance, such as reach, CTR or cost per lead.
Native advertising
Paid content designed to look like the content around it, such as a sponsored post in a feed.
Organic
Unpaid. Organic reach is the people who see your posts without any ad spend. Organic search results are the unpaid listings on Google.
Paid media
Any channel where you pay for visibility, including social ads, Google ads and vendor-paid listing upgrades on portals.
Pixel
A snippet of code that tracks visitor actions on your website and reports them back to an ad platform, so it can measure results and build retargeting audiences. Privacy settings and consent can limit how much it records.
PPC (pay per click)
An advertising model in which you pay only when someone clicks. You normally set a daily or monthly budget as a cap.
Reach
The number of different people who saw your content. Unlike impressions, each person counts once.
Relevance score
An old Meta ad metric that rated how well an ad resonated with its audience. Meta replaced it with ad quality diagnostics in Ads Manager, so you will not find it today.
Retargeting (remarketing)
Showing ads to people who have already visited your website or engaged with your page. Privacy changes, such as Apple's requirement for apps to ask permission before tracking, have reduced how much data is available, so expect smaller audiences.
ROI (return on investment)
The profit from an activity compared with what you spent on it. For agents, this often means commission from listings that began as marketing enquiries, compared with the marketing cost.
Schema markup
Code added to a web page that tells search engines what the page is about, such as a local business, a FAQ or a review. See schema markup for real estate.
SEM (search engine marketing)
Promoting a website through search engines, mainly by paid search ads.
SEO (search engine optimisation)
Improving your website and content so that it appears higher in unpaid search results. It takes longer than paid ads, but the benefit builds. Our post on SEO versus paid ads explains when to use each.
SERP (search engine results page)
The page you see after a search on Google or another search engine.
UGC (user-generated content)
Content created by customers or the community about your brand, such as reviews and tagged photos. See our guide to user-generated content for real estate.
UTM parameters
Short pieces of text added to a link so analytics can show which campaign, source or ad brought a visitor. See UTM tracking explained.
Using these terms in practice
When you review a campaign report, ask three questions: how many people did it reach, what did each lead cost, and how many of those leads became appraisals. If the report cannot answer those, ask for the tracking to be fixed.
If any term is used in a way that confuses you, ask for it to be explained in plain language. A good agency or consultant should be glad to do that.

Frequently asked questions
What is the difference between reach and impressions?
Reach counts each person once. Impressions count every time the content was shown, so one person who sees an ad four times adds four impressions but only one reach.
What is the difference between SEO and SEM?
SEO improves your unpaid search visibility over time. SEM usually refers to paid search advertising, where you pay to appear in search results.
Which digital marketing metric should agents watch most closely?
Cost per lead and the number of leads that become booked appraisals. Reach, impressions and clicks help diagnose problems, but they do not show whether the marketing is bringing in business.
Is Google My Business still a thing?
The product is now called Google Business Profile. It is the free listing that shows your agency in Google Search and Maps.
Key takeaways
- Reach and clicks are easy to inflate: judge campaigns by leads and booked appraisals.
- Cost per lead is more useful to an agent than cost per click.
- Some older terms, such as Meta's relevance score and Google My Business, have changed.
- If a report uses terms you do not understand, ask for a plain-language explanation.
