Mobile marketing explained: the seven channels, the consent rules, and what to measure

Mobile marketing is everything a business does to reach and serve a customer on a phone. It is not a channel of its own, it is the condition most of your marketing now runs in, and it covers seven distinct routes: the mobile web and mobile search, apps and push notifications, SMS and messaging apps, email read on a phone, advertising inside social and app environments, location and proximity, and wallet or QR journeys that start offline and finish on the device. Each route has its own consent rules and its own measurement. The practical order is to make the mobile web experience fast and easy first, then add channels that need permission, and to treat the phone as a personal device in everything you send to it.

This page explains the channels and how to run them. For the technical search side of a mobile site, see mobile SEO optimisation.

The seven channels

Channel	What it is	Best at	What it depends on
Mobile web and search	Your site, loaded on a phone from search, social or a link	Capturing demand that already exists	Speed, a working form, and content that is complete on mobile
Apps and push	An installed app and the notifications it may send	Repeat use and habit	Install, plus explicit notification permission
SMS and messaging apps	Text and business messaging to a number you hold	Time critical, high read rate messages	Opt in per channel, easy opt out, and each platform's template and policy rules
Email on a phone	Your ordinary email programme, read one handed	Owned reach with no gatekeeper	Single column design, large tap targets, a subject line that works truncated
In app and social advertising	Paid placements in feeds, games and apps	Reaching people who are not searching yet	Creative made for sound off vertical viewing, and clean measurement
Location and proximity	Local search, maps, store visit campaigns, geofenced targeting	Getting somebody nearby through the door	A complete business profile and accurate opening hours
Wallet and QR	Passes, tickets, loyalty cards, codes on packaging and print	Bridging offline to a digital journey	A landing page that loads instantly and does one thing

What is genuinely different about a phone

• One thumb, one column. Anything that needs two hands or a horizontal scroll loses the task.
• Interruption is the default. The session is short, often standing up, often resumed later on another device.
• Forms are the main point of failure. Every extra field costs completions. Use the right input types so the correct keyboard appears, allow autofill, and never ask for the same information twice.
• Payment is easier, if you let it be. Device payment sheets remove the step where most carts are lost.
• The device is personal. A message on a phone arrives beside messages from family. That is why consent and frequency matter more here than anywhere else.

Consent, in plain terms

Direct messaging to a phone is permission based, and the rules differ by country and by channel. Five habits keep you on the right side of all of them.

• Collect consent per channel, explicitly. An email subscriber has not agreed to receive SMS.
• Store when and how consent was given, and the exact wording they agreed to.
• Keep marketing messages separate from transactional ones, such as a delivery notification or a one time passcode.
• Make opting out a single step, honour it immediately, and never make somebody reply twice.
• Check the specific rules for each market you message into, and the policy rules of the messaging platform you use, before you build the campaign.

The build order for a business starting now

1. Make the mobile site fast and the forms short. This is where almost all of your current mobile traffic already goes, and improvements here raise every other channel.
2. Complete the local presence. Profile, hours, photographs, directions and a phone number that is answered. Phone searches are heavily local.
3. Design email for a phone first. Assume a one handed read: a short subject line, one clear action, large tap targets.
4. Add SMS for messages that are genuinely time critical. Appointment reminders, dispatch notices, a back in stock alert. Not a weekly newsletter.
5. Add paid social or in app advertising once you know what a customer is worth, with creative made vertical and legible with the sound off.
6. Build an app only when there is repeat use. An app earns its cost when customers come back weekly. For an annual purchase, the mobile web is the better product.

Creative that works on a phone

• Lead with the message in the first second, as text on screen, because most feed video is watched without sound.
• Shoot vertical and keep anything important away from the edges, where the interface sits.
• Use one idea per asset. Phone attention does not survive a second idea.
• Make the landing page continue the creative. A click from a specific advert into a generic home page wastes the click.
• Test the whole journey on a mid range phone on a normal connection, including the form and the payment step.

What to measure

Channel	The number that matters
Mobile web	Task completion rate on a phone, and the speed of the page that carries it
App	Retention at day seven and day thirty, not installs
SMS	Click rate, conversion per send, and opt out rate per send
Email	Clicks and conversions from mobile clients specifically
Paid in app and social	Cost per enquiry or per sale, with a stated attribution window
Location	Calls, direction requests and bookings from your profile
Wallet and QR	Scans, then the action after the scan

One cross device discipline makes all of this readable: write down the attribution model you use, including the window and whether you credit first or last interaction, and report the number alongside the model every time. A buyer who sees an advert on a phone and buys on a laptop is normal, so decide in advance how you will count it and keep counting it the same way.

Three mistakes that cost the most

• An interstitial on arrival. A pop up that covers the content a person came for, before they have read a word, is the fastest way to lose a mobile visitor. Delay it or lose it.
• A desktop journey with a mobile skin. Six form fields and a PDF do not become mobile friendly by being narrow.
• Treating SMS like email. The read rate is the reason it works and the reason overuse destroys it. Set a monthly cap and hold to it.

The local side of mobile marketing is where most smaller businesses see the fastest return, and the method is in local SEO. The speed side is in Core Web Vitals, and the email side in email deliverability and the flows that earn.

The mobile marketing explained questions worth an answer

What is mobile marketing in simple words?

It is reaching customers on their phones, through your website, your app, messages they agreed to receive, advertising inside the apps they use, and local search. The phone is the screen most people use most, so mobile marketing is mostly just marketing done properly for a small screen and a short session.

Is mobile marketing the same as SMS marketing?

No. SMS is one of seven channels and the most permission sensitive. Most businesses get more from a fast mobile site and a complete local presence than from text messages, and the two work best when SMS is reserved for messages the customer is waiting for.

Do we need an app?

Only if customers would use it repeatedly. Repeat purchase, bookings, accounts and loyalty justify an app. For occasional purchases, invest the same money in making the mobile site faster and the checkout shorter, and you will see more of it back.

How often can we message a mobile list?

Set a cap before you start, watch the opt out rate on every send, and only increase frequency while it stays flat. A monthly cap on SMS and a weekly rhythm on email suits most businesses, and your own opt out numbers will tell you where your limit is.

How do we measure mobile campaigns when people switch devices?

Pick one attribution model, write down the window, and report every number with that model attached. Add one number that cannot be argued with, such as enquiries or orders in the period, and read the two together. Consistency is what makes the series useful.

What should a mobile landing page contain?

One promise at the top, the proof under it, one action, and nothing else above the fold. Then the detail for people who scroll, and the same action again at the end. Load it on a phone and complete the action with one thumb before you publish it.

The moment on the phone that no report covers

SMS opens, app sessions and click to call all land in reports. A person on a phone asking an assistant out loud for a nearby option leaves no trace in any of them.

Voice or typed, the question is short and the answer names a few places. Ask it the way your customer would, standing on a street in your service area. AI Knows Us sends such questions to the main assistants and lists which businesses are returned.
