Digital marketing covers everything from search ads and SEO to social media and email, and its results can be measured. We explain the channels, where to start, how to build a strategy and what to look for in an agency.
Digital marketing means promoting a product or service to the right people through online channels and measuring the result of that effort. The ads you see on Google, sponsored posts on Instagram, a website ranking near the top of search results, a reminder email sent to someone who left items in their cart: all of these are part of digital marketing. In this article we answer the question “what is digital marketing?” in plain language, walk through the channels one by one, and explain where a small or mid-sized business should start and what to look for when choosing a digital marketing agency.
What is digital marketing, and how is it different from traditional marketing?
With traditional marketing you pay for a newspaper ad, a radio spot or a roadside billboard, and you usually have to guess how many people saw it and how many contacted you because of it. The real difference with digital marketing is measurability. You can see how many times your ad was shown, how many people clicked, and how many of them filled in a form, called you or made a purchase.
The second difference is targeting. In digital advertising you can show your message to people in a specific area, people searching for a specific thing or people with specific interests. The third is flexibility: you can pause an ad that is not working without waiting months, and move the budget to the channel that performs. That flexibility is as much a responsibility as an opportunity; if tracking is not set up properly, digital marketing is just as much a shot in the dark as traditional advertising.
The channels of digital marketing
Digital marketing is not a single tool but a set of channels that complement each other. Each one is strong in a different situation.
Search ads (Google Ads)
These are the ads that appear above the results when someone types “boiler repair” or “teeth whitening” into Google. Their strength is that the demand already exists: the person is looking for a solution right now. You usually pay per click, and spending stays within the limits you set. For a step-by-step look at setting up a campaign, see our guide to advertising on Google.
Social media ads (Meta, TikTok, LinkedIn)
Meta ads run on Facebook and Instagram, TikTok ads on TikTok, and LinkedIn ads on the professional network. Unlike search ads, the person is not looking for you; the ad creates demand by catching their attention. They work well for products that can be shown visually, for introducing new brands and for e-commerce. LinkedIn is also worth considering for businesses that sell to other companies (B2B).
SEO and local SEO (Google Maps)
SEO is the work of getting your website to rank higher in Google’s free (organic) results: technical foundations, content and the site’s credibility. There is no cost per click, but results take time and build up over months. Local SEO is about showing up for “near me” style searches and on Google Maps, with your Google Business Profile at the centre. We cover the basics in detail in our article What is SEO?
Social media management and content marketing
Posting regularly on your accounts, replying to messages and producing videos that present your brand, independently of ads, is social media management. Content marketing is a broader idea: earning trust with content that is genuinely useful to your customers, such as blog posts, guides and videos. It does not bring sales overnight, but it helps your ads and search presence perform better.
Email marketing and remarketing
Email is a low-cost way to send offers, reminders or updates to people who have given you permission. In Turkey, sending commercial electronic messages requires the recipient’s consent, and businesses are expected to follow the rules of the national commercial message management system (IYS). Remarketing means reaching people again with ads after they visited your site without taking action. Because it gives a second chance to visitors who did not decide on their first visit, it is an efficient channel for many businesses, but it must be set up in line with cookie consent and personal data protection (KVKK) rules.
Website and landing page
Traffic from every channel ends up somewhere: on your website or on a landing page built for a specific campaign. If that page loads slowly, looks messy on mobile or leaves visitors unsure what to do next, even the best-built ad wastes money. That is why your website is less a channel of digital marketing and more its foundation.
Paid, owned and earned media
A practical way to classify the channels is to split them into three groups:
| Type | Examples | Characteristic |
|---|---|---|
| Paid media | Google Ads, Meta, TikTok and LinkedIn ads | Delivers results quickly; visibility stops when payment stops. |
| Owned media | Your website, blog, social media accounts, email list | You are in control; it takes effort and gains value over time. |
| Earned media | Customer reviews, shares, press coverage, links from other websites | The most convincing; it cannot be bought and is earned through good service and good content. |
A healthy digital marketing plan balances all three. A business that relies only on paid media becomes invisible the day it cuts its budget; a business that waits only for organic growth may struggle to find demand in the first months.
Where should a small or mid-sized business start with digital marketing?
There is no single recipe for every business, but two questions determine the right order: how flexible is your budget, and how long does your customer think before deciding?
- Check the foundations first. Does your website load quickly on mobile, are your phone and WhatsApp links easy to find, and is your Google Business Profile live with correct details? If not, fix these before spending on ads.
- If demand already exists, start with search ads. For services people search for at the moment of need, such as plumbers, locksmiths, air-conditioning repair or clinics, Google Ads can bring measurable enquiries fairly quickly. If you serve a specific area, running local SEO alongside makes sense.
- If your product sells by being seen, prioritise social media ads. For clothing, home decor, cosmetics or a brand-new brand that people need to see before they would search for it, Meta and TikTok ads can create demand.
- If your sales cycle is long, make room for content and remarketing. Where decisions can take weeks, such as business services or high-value products, a single ad click rarely turns into a sale. Trust-building content, email and remarketing carry people through that period.
- Plan SEO as a long-term investment. Even on a tight budget, consistent SEO work gradually reduces your dependence on ad spend.
With a limited budget, setting up one or two channels well, measuring them and scaling what works usually beats trying every channel at once.
Measurement in digital marketing: which numbers matter?
If measurability is the biggest advantage of digital marketing, looking at the wrong numbers is the most common mistake. Likes, impressions and clicks do not make your business money on their own. These are the indicators that really matter:
- Conversion tracking: Correctly reporting actions such as form submissions, phone calls, WhatsApp messages or purchases to your ad platforms and analytics tool. Without it, none of the other numbers can be trusted.
- Cost per acquisition (CPA): Total ad spend divided by the number of conversions. It shows what you pay to win a customer.
- ROAS (return on ad spend): Revenue from ads divided by ad spend. But revenue is not profit; you still need to work out whether you are profitable after product costs and other expenses.

How to build a digital marketing strategy
A good digital marketing strategy does not have to be a long slide deck; it is a clear answer to these six points:
- Goal: What do you want? Quote requests, online sales, appointments… Write the goal down with a number and a timeframe.
- Audience: Who is your customer, where are they, what problem brings them to you, and what do they weigh up before deciding?
- Channel: Which channel reaches this audience most directly? The roadmap above helps here.
- Budget: What is the most you can spend to win one customer? Treat the ad budget and the agency or management fee as separate items.
- Testing: Compare different ad copy, visuals, targeting and landing pages. The first setup is rarely the best version.
- Reporting: Check regularly how close you are to the goal; stop what does not work and scale what does.
What to look for when choosing a digital marketing agency
When comparing digital marketing agencies, these points matter far more than a polished presentation:
- Transparent reporting: Spend, conversions and cost per customer should be shared in a clear way. Ask questions if an agency only reports impressions and clicks.
- You should own the accounts: Your Google Ads account, Meta ad account, analytics tool and Business Profile should belong to your business, with the agency given access only. If you part ways, your historical data stays with you.
- Guarantees are a red flag: Be cautious of offers that guarantee “number one on Google” or a set number of sales. No agency controls search results or the ad auction.
- An effort to understand your business: An agency that asks about your goals, customer profile and profit margin before quoting makes a sounder start than one selling the same package to everyone.
- A clear contract: Whether the ad budget is included in the fee, the contract length and the cancellation terms should all be in writing.

Frequently asked questions
Are digital marketing and digital advertising the same thing?
No. Digital advertising is the paid part of digital marketing. Digital marketing also includes SEO, social media management, content, email and work on your website.
How much budget should I set aside for digital marketing?
There is no figure that fits everyone. The budget depends on competition in your sector, the area you target and the profit a customer brings you. The sensible approach is to work out the most you can spend per customer and measure the real cost with a small test budget.
When will I see results?
Search and social media ads can start bringing traffic and enquiries shortly after going live, but campaigns take a few weeks to settle and improve. SEO and content marketing usually build results over months.
What is performance marketing?
Performance marketing is an approach where spending is managed according to directly measurable results (forms, calls, sales). Success is judged not by likes or impressions but by figures such as cost per acquisition and ROAS.
Can I do digital marketing myself?
Yes, especially at the start and with small budgets. If your time is limited, or results do not keep up as spending grows, getting help from a specialist while keeping ownership of your accounts can be more efficient.
