Blurring of Social and Business Boundaries

Targeted advertising is when a social media platform uses the data it holds about you to decide which advert you see. The platform is not choosing adverts at random: it matches each advert to users whose details and interests fit what the advertiser asked for.

When an organisation sets up a paid advert, it can choose factors such as gender, age, location and interests. For example, a company selling revision planners might target 14- to 16-year-olds in Manchester who follow study or homework accounts. The platform compares those choices with the profile data it stores, such as your age, town and the pages you like, and shows the advert only to users who match.

Third-party cookies add to this picture. These are small files placed by a company other than the website you are visiting, and they record pages you view across different websites. If you spend time reading about camping tents on an outdoor shop's site, a third-party cookie can pass that interest to an advertising platform, which may later show you adverts for sleeping bags. Your browsing outside the platform can therefore shape the adverts you see inside it, and it helps the platform build a picture of what you like.

Because the data is different for each person, different users receive different adverts, and each advert is more relevant to that user's age and interests.

This is the aim of targeted marketing: to put an advert in front of the people most likely to want the product, rather than paying to show it to everyone. It also shows how personal and business activity can blur. Your personal posts, likes and browsing create the data that businesses use to aim adverts at you, so using social media for fun affects what commercial messages you receive.

A social media advertising campaign is a paid set of adverts placed in social feeds, so they appear between people's personal posts. Businesses use social media in this way because they can set the campaign up themselves, choose who sees it and change it quickly if it is not working.

Setting up a campaign

• Format: an image is quick and cheap and suits one clear offer, such as a free drink with breakfast; a video costs more to make but can show a product in use.
• Type of user to target: the advertiser picks the audience most likely to buy, so the budget is not wasted on people who will never be interested.
• Budget: the money set aside for the campaign; a bigger budget buys more showings to more people, while a small one means the advert appears less often.
• Duration: a few days to advertise an event, or several weeks to build regular custom.

What an advert is designed to do

A single campaign can use several purposes in turn: a trampoline park might run a video to build awareness, then a booking link to create conversions, then a form for a taster session to generate leads.

Analytics and trends show the business the demographics of the people who responded, such as their age, gender and location, and which adverts gained the most likes, comments and shares. Comparing an image with a video, for example, shows which earned more engagement, so the next campaign's budget goes on the format that worked.

An influencer, or paid content creator, is someone with a social media following who is paid to promote products or services. This is called paid promotion. The creator gains money or free products, while the business reaches a large audience.

Why both sides agree

The creator is paid a fee, or sometimes given free products, to feature a business in their posts. In return, the business reaches the creator's followers more quickly and widely than it could through its own account. For example, a small climbing gym pays a local climber with 30,000 followers to show its new bouldering wall in a short video. Many viewers already watch his clips and value his opinion, so the gym becomes known to people who have never visited.

Brand awareness and trust

This builds brand awareness: more people recognise the business and what it sells. It can also build trust, because followers already listen to that creator. A recommendation from someone they choose to follow can feel more believable than a company advertising itself. That trust depends on the promotion being honest; if you follow a creator and feel tricked, the creator's reputation and the business's image can suffer.

Advertising must be acknowledged

Some platforms require paid promotions to be clearly acknowledged as advertising. The creator might add a paid partnership label or state that the post is an advert. This tells followers that money or gifts were involved, so they can judge the recommendation fairly. It also makes the boundary between a personal post and business content visible: the same friendly video has become commercial promotion.

The boundary between work and personal life blurs when the same digital systems are used for both. Your phone, messaging apps and social media can be how you chat with friends and how an employer reaches you, which makes it harder to switch off.

Contact outside working hours

Digital systems make it quick for a business to reach staff, and some employers expect people to install a work app on their own phone. A notification about a changed shift or a customer message can arrive on a day off or after midnight, and because it is your own device you see it straight away. A read receipt that shows the message has been opened makes it awkward to ignore. As a result, staff may answer messages and complete small tasks outside their contracted hours, without extra pay — a swimming teacher replying to a booking message on a rest day, for example.

One account, two audiences

Your contact list and follower list hold everyone at once: family, friends and people you know through a job, with no switch to separate them. A message about a rota change sits between birthday messages, and a photo meant for friends lands in the same feed as a post about work. Because the audiences are mixed, your online behaviour can have professional consequences: a joke posted on a personal account, or a photo you are tagged in, may be seen by a manager, colleague or customer and damage your professional reputation.

Professional networks in your own time

Business-focused social networks are built for work rather than chat. In their own time, employees use them to build contacts, follow news in their field and look out for vacancies, and past colleagues stay in touch through them. Because a profile shows someone's roles and skills in one place, and contacts pass on openings, it is easier for employees to hear about a new role and move between jobs — sometimes without actively applying.

Employers often look at what you share online when they are deciding who to shortlist for a job. Checking someone's public posts in this way is sometimes called screening. A search of your name, profile and recent comments can reveal things that a CV would not.

What employers may learn

Your online activity can give an employer useful insight into how you communicate, what interests you and how you present yourself. For example, if you apply for a customer service role and your public posts show you politely answering questions in a local hobby group, that supports your application. The reverse is also true: rude replies or jokes that target a group of people can raise doubts about how you would treat customers or colleagues.

Your posts can be used against you

Personal posts can be seen by people outside your friends list, including employers. Even a post you delete may already have been screenshotted or shared. Privacy settings reduce the risk but do not make you invisible, especially if a friend's account is public or you comment in a public group. The same applies to anything you write on a public forum or blog.

This can affect your job prospects, your professional reputation and your employment. An employer might decide not to shortlist you or withdraw an offer, and an existing employee can face disciplinary action if their posts damage the organisation's image. A personal account is not automatically separate from working life: what you post online shapes how trustworthy, reliable or suitable you appear to an employer.
