Useful calculations and cleaner campaign links—without an account.

Campaign URL builder
Create a link with UTM parameters for source, medium and campaign. Use consistent naming and reserve these tags for external campaign links. Adding UTMs to internal navigation can make measurement harder to interpret.
Existing query parameters and fragments are preserved. A parameter with the same UTM name is replaced. Read Google’s campaign URL guidance for reporting context.
Word and character counter
Count words separated by whitespace and characters including spaces. Reading time uses an approximate 200 words per minute. Character counts are useful for editing; they do not predict how Google will display a title or snippet.
Campaign metrics calculator
Enter spend and revenue in the same currency. ROAS = revenue ÷ spend; cost per click = spend ÷ clicks; cost per conversion = spend ÷ conversions; conversion rate = conversions ÷ clicks × 100. A zero denominator returns N/A.
Attributed revenue is not profit. Taxes, product costs, refunds and attribution settings can change the business interpretation. Multiple conversions per click can produce a rate above 100%.
For context around these numbers, explore PPC management and measurement planning.
