What is the difference between impressions and reach?

Impressions count every time your post appears on a screen, even if the same person sees it three times. Reach counts unique people. A post can have 1,000 impressions from 400 people, meaning your reach is 400. Reach tells you how many people you touched. Impressions tell you how many times your content showed up.

What is a good engagement rate for a solo founder?

For a solo founder with under 5,000 followers, an engagement rate of 3 to 5 percent is solid. Above 5 percent means your content is resonating. Below 2 percent means you may be posting at the wrong time or your audience is not the right fit. Platform averages for 2026 sit around 1 to 3 percent for most business accounts.

Should I track vanity metrics like follower count?

Follower count is a proxy, not a goal. A solo founder with 500 engaged followers who click links and reply to posts is worth more than one with 5,000 passive followers. Track followers to spot trends, but do not optimize for it. Optimize for clicks, signups, and replies instead.

What is the one social media metric I should watch every week?

For most solo founders, the single most important weekly metric is link clicks or website visits from social. If your social media presence is not sending people to your site, your product page, or your newsletter signup, the other metrics do not pay bills. Set up UTM parameters on every link you post so you can track which platform and which post type actually drives traffic.

How do social media algorithms work for small accounts?

Every platform algorithm prioritizes engagement signals: comments, shares, saves, and time spent viewing. For small accounts, the algorithm tests your post on a small slice of your followers first. If it performs well on that sample, it expands the reach. This means quality beats frequency. One post that gets 20 genuine comments performs better than five posts that get two likes each.

Social media marketing glossary for solo founders

All posts

Most social media marketing glossaries list 80 terms. They are written for marketing teams with specialist roles: a content strategist, a paid media buyer, a community manager, and an analytics person who lives in dashboards.

Solo founders have none of those people. You are the strategist, the media buyer, the community manager, and the analytics person. You have about 90 minutes a week to post on two or three platforms and maybe $10 a day for ads.

This glossary is not 80 terms. It is 25. These are the social media marketing terms that actually affect your decisions, your budget, and your time. If a term did not make this list, a solo founder does not need to think about it yet.

The terms you hear in every meeting

These five terms come up constantly. If you understand nothing else, understand these.

Algorithm. The set of rules a social media platform uses to decide which posts appear in a user's feed and in what order. Every platform has its own algorithm, but they all share one DNA: they reward content that keeps people on the platform. For a solo founder, the practical takeaway is simple. Comments beat likes. Saves beat shares. And anything that starts a conversation gets pushed further than anything that does not.

Engagement rate. Engagement rate is the percentage of people who saw your post and did something with it: liked, commented, shared, saved, or clicked. The formula is (total engagements divided by impressions or reach) times 100. For a solo founder with a small following, a 3 to 5 percent engagement rate is healthy. Below 2 percent and you need to change what you are posting or who you are posting to.

Impressions. The total number of times your post appeared on a screen. If one person sees your post three times in their feed, that is three impressions. Impressions measure visibility, not audience size. A high impression count with zero clicks means your content is showing up but nobody is interested.

Reach. The number of unique people who saw your post. If 400 people saw your post and each saw it twice, your reach is 400 and your impressions are 800. Reach tells you how many people you touched. It is the better metric for measuring brand awareness.

Click-through rate (CTR). The percentage of people who clicked a link in your post after seeing it. If 500 people saw your post and 10 clicked the link, your CTR is 2 percent. This is the metric that connects social media activity to actual website traffic. A social media strategy without CTR measurement is a hobby, not a growth channel.

The money terms

These are the paid advertising terms. Even if you are not running ads yet, you will hear these in every conversation about scaling social media.

Cost per click (CPC). The amount you pay each time someone clicks your ad. CPC varies wildly by platform, audience, and competition. LinkedIn can run $5 to $12 per click for B2B audiences. Meta can be $0.30 to $2. TikTok often lands under $0.50. For a solo founder with a small budget, CPC determines how many people you can afford to reach. A $10 daily budget at $2 CPC means five clicks a day. At $0.50 CPC, it means 20 clicks. That difference compounds fast.

Cost per mille (CPM). The cost per 1,000 impressions. "Mille" is Latin for thousand. CPM is the standard pricing model for brand awareness campaigns. If you pay a $10 CPM and your ad gets 10,000 impressions, the cost is $100. For a solo founder, CPM campaigns make sense when your goal is visibility, not direct response. They are cheaper per impression than CPC but harder to tie to revenue.

Cost per acquisition (CPA). The total ad cost to acquire one customer or one specific action like a signup. CPA is the metric that tells you whether your ads are profitable. If your product costs $29 per month and your CPA is $15, you are in good shape after one month of retention. If your CPA is $90, you need to fix your targeting, your creative, or your landing page before scaling.

Return on ad spend (ROAS). Revenue generated divided by ad spend. A ROAS of 3x means you earned $3 for every $1 spent. ROAS is the headline number managers ask for, but it hides important detail. A 5x ROAS on $50 of spend means nothing for a business that needs $5,000 in monthly revenue. Watch ROAS alongside total spend and total revenue.

Conversion tracking. The method of tracking when someone who clicked your ad completes a desired action like a signup, a purchase, or a demo booking. Without conversion tracking, you are throwing money into a black box. You see clicks but never learn which clicks became customers. Every platform has its own conversion pixel or tracking code. Install it before you spend a dollar on ads.

The content terms

These are the terms that describe what you actually post. A solo founder produces four or five content formats. Know these five and you have your content engine mapped out.

User-generated content (UGC). Content created by your users or customers, not by you. UGC can be a testimonial video, a tweet about your product, or a screenshot of your dashboard shared by a happy user. For a solo founder, UGC is the most cost-effective content strategy available. One genuine customer video can outperform five polished brand posts.

Evergreen content. Content that remains relevant and useful months after publication. A tutorial on how to set up Google Tag Manager is evergreen. A post about a platform algorithm change is not. Solo founders should aim for a 70/30 split: 70 percent evergreen content that works for you over time, 30 percent timely content that shows you are active and current.

Carousel. A post format that contains multiple images or slides users can swipe through. Carousels consistently generate higher engagement than single-image posts because users spend more time interacting with them. On LinkedIn, carousels often outperform text-only posts by 2x to 3x on impressions. On Instagram, they get more saves than Reels for educational content.

Stories. Short, vertical photo or video posts that disappear after 24 hours. Stories live on Instagram, Facebook, TikTok, and increasingly LinkedIn. They are ideal for behind-the-scenes content, quick polls, and time-sensitive announcements. For a solo founder, stories are the lowest-effort format that still gets seen. A 15-second phone video of your workspace can outperform a polished feed post.

Caption. The text that accompanies an image or video post. Captions are where the actual messaging lives. A strong caption leads with a hook in the first line, delivers value in the middle, and ends with a clear call to action. On platforms like LinkedIn and Instagram, captions often determine whether a post gets shared or scrolled past.

The platform mechanics

These are the nuts and bolts of how platforms work. You do not need to know all 15 platform-specific features. You need these five.

Hashtag. A word or phrase preceded by the # symbol used to categorize content. Hashtags help your posts appear in topic-based searches and feeds. On Instagram, 3 to 5 targeted hashtags outperform 20 generic ones. On LinkedIn, hashtags are optional and often ignored. On TikTok, trending hashtags can put your video in front of a new audience overnight.

Handle. Your username on a social platform, usually preceded by @. Your handle is how people find you, tag you, and mention you. Pick one handle and use it across every platform. A consistent handle builds recognition faster than a clever one that changes per platform.

Direct message (DM). A private message sent from one user to another on a social platform. For solo founders, DMs are where actual relationships and sales conversations happen. A public comment starts the conversation. A DM closes it. Check your DM requests folder regularly. Many platforms hide messages from non-followers in a separate inbox.

Feed. The main scrolling stream of content a user sees when they open a social app. The feed is where your permanent posts live on your profile. It is distinct from Stories, which disappear, and from the algorithmic For You pages on TikTok and Instagram Reels. For a solo founder, the feed is your content archive. Anyone who discovers you and scrolls your feed should understand what you do within three posts.

Bio. The short description section on your profile. Your bio is the most valuable 150 characters you own on any platform. It should answer three questions in this order: what you do, who you do it for, and why someone should follow you. Include one clear call to action and one link. If your bio says "Founder" and nothing else, you are leaving free traffic on the table.

The strategy terms

These are the terms that separate posting for fun from posting for growth. You do not need a marketing degree to use them. You just need to understand what they mean for a one-person operation.

Social listening. The practice of monitoring social media for mentions of your brand, your competitors, and your industry keywords. At the enterprise level, this means expensive tools and dedicated analysts. For a solo founder, social listening means setting up Google Alerts for your company name and competitor names, and spending 10 minutes a week searching relevant subreddits and X/Twitter for your target keywords.

Audience targeting. The practice of defining who sees your content or ads based on demographics, interests, behaviors, or custom data. For organic content, targeting means posting on the platforms where your customers actually spend time. For paid ads, it means defining audiences narrowly enough that your $10 daily budget reaches people who might actually buy, not everyone who might scroll past.

Content calendar. A schedule of what you will post and when. For a solo founder, a content calendar does not need to be a spreadsheet with 12 columns. It can be a Notion page with three slots per week: one educational post, one personal story, and one promotional post. The value is not in the tool. It is in removing the daily decision of what to post.

Brand voice. The consistent personality and tone your brand uses across all communication. A solo founder's brand voice is usually just their own voice, slightly tightened. The key is consistency. If your LinkedIn posts are formal and your TikTok videos are casual and your Twitter replies are sarcastic, your audience gets three different versions of you. Pick a lane and stay in it.

Key performance indicator (KPI). A specific, measurable value that tells you whether your social media activity is working. For a solo founder, pick three KPIs and ignore everything else. A good starter set: (1) website visits from social, (2) new email subscribers from social, and (3) replies or DMs that led to a sales conversation. Follower count and likes are not KPIs. They are vanity metrics.

What to do with these terms

Knowing the terms is step one. Step two is applying them to your specific situation. A solo founder selling B2B SaaS needs different platforms, different content, and different KPIs than a solo founder selling a consumer product. The terms are the same. The application changes.

Start with your KPIs. Decide what success looks like before you post anything. Then pick two platforms where your customers actually spend time. Use the content terms to plan a simple weekly rotation. Use the money terms to decide if and when paid promotion makes sense. And use the platform mechanics terms to optimize as you go.

The goal is not to know 80 terms. The goal is to know 25 terms well enough to make better decisions in 90 minutes a week.
