UTM tags are not glamorous, but they are the difference between knowing whether a campaign worked and guessing. The best convention is not the most complex one. It is the one your team can apply consistently across paid social, email, affiliates and partner activity.How to calculate profitable ROAS when returns and fulfilment costs matter
Return on ad spend (ROAS) is simple: revenue divided by advertising spend. A £5,000 campaign that drives £20,000 in tracked revenue has a 4.0x ROAS. The problem is that revenue is not profit. For an ecommerce business, a seemingly excellent ROAS can still lose money once product cost, returns, payment fees and fulfilment are included.How to write product and category page titles that earn the click
A page title is a short promise about what the searcher will find. It should help a person distinguish your result from the alternatives, not try to repeat every possible keyword. For ecommerce pages, clarity usually wins: product or category first, the most useful qualifier second, then the brand if it adds recognition.Free forever - a donation keeps it that way
No accounts, no limits, no data collection, and that won't change. If these tools save you time, a small contribution towards hosting and upkeep wouldn't be missed.
