CPM Calculator vs Semrush: the short verdict
CPM Calculator and Semrush are both listed under Marketing on Launchory, which is why founders weigh them against each other: CPM Calculator describes itself as “Free advertising calculators for CPM, spend, impressions, CPC, CTR, and eCPM”, Semrush as “All-in-one SEO and online visibility toolkit”. On cost, CPM Calculator is the cheaper way in — it is listed as free to use, while Semrush is paid once its free trial ends. Launchory records the pricing model, not price points, so the numbers live on each product's own pricing page. All of that comes from what each product records on Launchory — category, pricing model and tags — not from hands-on testing.
At a glance
Free advertising calculators for CPM, spend, impressions, CPC, CTR, and eCPM.
CPM Calculator is a free browser-based toolkit designed for advertisers, marketers, publishers, media buyers, freelancers, and small businesses that need to plan and evaluate digital advertising campaigns. The main calculator lets users enter any two values among CPM, total ad spend, and impressions, then instantly calculates the missing value. This makes it easy to estimate campaign costs, compare media plans, and check whether a proposal fits an available budget. The website also includes focused calculators for CPC, CTR, eCPM, break-even ROAS, campaign reach, campaign comparison, and YouTube earnings. Each calculator explains the formula, shows the result immediately, and keeps the workflow simple for users who do not want to build spreadsheets or search for formulas. The tools are useful for planning new campaigns, reviewing past performance, comparing advertising channels, and communicating estimates with clients or teammates. CPM Calculator works directly in the browser and does not require an account, installation, or subscription. Users can select a currency label, enter their campaign data, and receive results without hidden currency conversions or unnecessary steps. The responsive interface works on both desktop and mobile devices. Unlike a large advertising platform, CPM Calculator is independent of any particular advertising network. It focuses on transparent calculations and practical planning tools that can be used across display advertising, social media campaigns, video advertising, publisher inventory, and other paid media channels. All core calculators are free to use.
All-in-one SEO and online visibility toolkit
Semrush is an online visibility and marketing platform best known for search engine optimisation. It provides keyword research, competitor analysis, site auditing, rank tracking, backlink data, content tools and advertising research, used by marketers, agencies and businesses to grow organic and paid search traffic. Its breadth is the defining feature. Where some tools specialise in one aspect of SEO, Semrush covers most of the workflow in one subscription. The Keyword Magic Tool and keyword gap analysis find search terms and opportunities competitors rank for; Domain Overview and Traffic Analytics estimate any site's traffic, top pages and sources; Site Audit crawls a website for technical issues; Position Tracking monitors rankings by location and device; and the Backlink Analytics database shows linking domains. Content tools help plan topics and optimise articles, and local SEO features manage business listings and reviews. Semrush has expanded beyond SEO into a broader marketing toolkit. Advertising research reveals competitors' paid search keywords and ad copy, social media tools schedule and analyse posts, and market research features analyse industries and audiences. In response to AI search, it has added tools that track how brands appear in AI assistants and answer engines and recommend ways to improve visibility. An app centre offers additional specialised tools. Semrush is a paid subscription with tiers by number of projects, tracked keywords and users, and a free account with limited queries. The main criticisms are cost, especially for small businesses and when adding users and add-ons, and the reality that third-party traffic and keyword estimates are approximations rather than exact data. Alternatives include Ahrefs, its closest competitor, particularly strong in backlink data; Moz Pro, with its Domain Authority metric; SE Ranking and Mangools for more affordable suites; Similarweb for market and traffic intelligence; Screaming Frog for technical crawling; Surfer for content optimisation; and Google Search Console for free first-party data. Choose Semrush when you want one comprehensive toolkit for SEO, competitor research and search advertising.
