Digital marketing is promoting a business through online channels: search engines, social media, email, websites, messaging apps and online ads. The video explains the idea and its key components; here is the written summary.
The key components
- Website: the home base where every other channel sends people.
- Search engine optimisation (SEO): earning free visibility on Google.
- Online advertising: paid ads on Google, Meta (Facebook and Instagram), YouTube and marketplaces.
- Social media marketing: building an audience and trust through regular content.
- Content marketing: blogs, videos and guides that answer customer questions.
- Email and WhatsApp marketing: staying in touch with leads and customers.
- Analytics: measuring what works so you can do more of it.
How the parts work together
A typical customer might see your Instagram reel, search your name on Google, read reviews, visit your website, and finally message you on WhatsApp. Each channel does a different job, and they work best together. A plan that uses two or three channels well beats one that tries everything badly.
Where to start
- Know who your customer is and what they search for.
- Get a fast website and a complete Google Business Profile.
- Pick one or two channels where your customers spend time.
- Measure enquiries and cost per enquiry every month.
