About social media marketing tools

Social media work is part creative, part measurement. This group of free tools covers both: calculators for engagement rate, follower growth, social ROI and influencer ROI, plus writing helpers that preview posts and count characters against each platform's limits, and a lightweight content calendar for planning.

If you report to a client or manager, the calculators turn raw likes, reach and spend into figures you can compare month to month. If you write the posts, start with the post preview or character counter so captions are not cut off. Everything runs in your browser, and your drafts and numbers are not uploaded.

Frequently asked questions

Should I calculate engagement rate by followers or by reach?

Both are useful. Engagement by followers is easy to compare across accounts because follower counts are public. Engagement by reach shows how people who actually saw the post responded, which is better for judging content quality. Pick one method, label it clearly in reports and stick with it so month-to-month comparisons stay fair.

What is a good engagement rate on Instagram or LinkedIn?

Published averages vary by platform, industry, account size and how engagement is defined, so any single benchmark can mislead. A more reliable approach is to track your own engagement rate over time, compare similar post formats against each other, and look for what lifts your own baseline.

How do I prove the ROI of social media?

Tag links with UTM parameters, use tracked discount codes or landing pages, and record all costs including tools, people and content production. Then compare attributed revenue with total cost. Remember that social often assists conversions that are credited to other channels, so also look at assisted conversions in your analytics.
