Why 360ecom?
360ecom is a knowledge and tools site for online businesses. We do not invent testimonials, traffic numbers or expert panels. The value is the explanation, the formula and the next page to read. Learn more on the about page. Corrections and questions go to the contact page.
Explanations are written for people who run or build stores, not for generic search snippets.
Terms, formulas and platform differences are explained in plain English before they get technical.
Tools run in the browser, validate inputs and show the formula used for every result.
Cornerstone guides are maintained as living references and linked to supporting articles and tools.
Each article starts from a real question, then adds examples, comparisons and next steps.
Published and updated dates are visible. Material changes are reflected in the article, not hidden.
