- Reach and impressions are different: reach counts unique users; impressions count total views.
- Engagement rate is the key metric for assessing content performance beyond raw view counts.
- Organic and paid content serve different purposes in a balanced social media strategy.
- UGC (User-Generated Content) is a powerful tool for building authentic brand credibility.
- Understanding algorithm behaviour is central to maximising organic reach on any platform.
Social media is one of the most globally uniform professional fields — industry terminology is almost entirely in English, regardless of the country or language of the team using it. Social media managers in Warsaw, São Paulo, and Seoul all talk about engagement rates, content calendars, and A/B testing using the same English terms. Mastering this vocabulary is essential for anyone working in, or aspiring to work in, the digital marketing industry.

What does 'engagement rate' mean in social media English?
Engagement rate is the percentage of an audience that interacts with a piece of content through likes, comments, shares, saves, or clicks. It is calculated as total engagements divided by reach (or impressions), multiplied by 100. A high engagement rate indicates that content is resonating with its target audience.
What is the difference between 'reach' and 'impressions'?
Reach is the number of unique users who have seen a piece of content. Impressions is the total number of times the content was displayed, regardless of whether the same person saw it multiple times. For example, if one post was seen twice by 500 people, its impressions would be 1,000 but its reach would be 500.
What does 'organic' vs 'paid' mean in social media?
Organic content is posted and distributed without paying for promotion — it reaches people through natural algorithms, shares, and followers. Paid content (also called 'promoted' or 'boosted' content) is supported by an advertising budget to reach a wider or more targeted audience. Most social media strategies combine both organic and paid approaches.
What is a 'content calendar' in social media management?
A content calendar (also called an editorial calendar) is a planning document that maps out what content will be published, on which platforms, on which dates, and in what format. It helps social media teams work in an organised way, maintain a consistent posting schedule, plan around seasonal events, and ensure a balanced mix of content types.
What does 'UGC' stand for in social media?
UGC stands for User-Generated Content. It refers to any content — photos, videos, reviews, testimonials, or posts — created by consumers or fans rather than the brand itself. UGC is highly valued because it is perceived as more authentic and trustworthy than branded content. Brands often encourage UGC through contests, branded hashtags, or ambassador programmes.
What is a 'call to action' (CTA) in social media?
A call to action (CTA) is a prompt in a social media post or advertisement that encourages the audience to take a specific action. Common examples include: 'Click the link in bio', 'Share this post', 'Tag a friend', 'Save this for later', 'Comment below', or 'Shop now'. Effective CTAs are clear, specific, and aligned with the content's objective.
What does 'going viral' mean?
Content 'goes viral' when it spreads rapidly across social media platforms and reaches a far larger audience than the creator's usual following, typically through shares, reposts, and word of mouth. There is no fixed threshold for virality — it is relative to the account's normal reach. Viral content is usually highly emotional, surprising, relatable, or entertaining.
What is an 'algorithm' in the context of social media?
A social media algorithm is a set of computational rules used by platforms (Instagram, TikTok, LinkedIn, etc.) to determine which content is shown to which users and in what order. Algorithms typically prioritise content based on factors such as engagement rate, relevancy to the user's interests, recency, and relationship with the creator. Understanding how algorithms work is central to social media strategy.
What is 'influencer marketing'?
Influencer marketing is a form of social media marketing that involves partnering with individuals who have established audiences on social media (influencers) to promote a brand, product, or service. Influencers are categorised by audience size: nano (1K-10K followers), micro (10K-100K), macro (100K-1M), and mega/celebrity (1M+). Each tier offers different trade-offs between cost, reach, and authenticity.
What does 'A/B testing' mean in social media marketing?
A/B testing (also called split testing) is the practice of running two versions of the same content or advertisement simultaneously to see which performs better. For example, you might test two different headlines, images, or CTAs with different audience segments and then scale up the version with the better results. It is a fundamental data-driven approach to optimising social media performance.
