Key Terms Explained

Character limit

The maximum number of characters a platform will display before it truncates your text. Twitter/X allows 280, Google titles render around 60 and meta descriptions around 160.

Reading time

An estimate based on an average adult reading speed of 200–250 words per minute. Publishers use it to set expectations above the fold.

Whitespace normalisation

Collapsing duplicated spaces, tabs and line breaks so pasted text from PDFs or Word behaves predictably.

Slug

The URL-safe, lowercase, hyphenated version of a title used in web addresses.

Why this matters

Text is the raw material of everything you publish — an ad headline, a product description, a university essay or a support reply. Getting the length, casing and structure right is the difference between copy that ships and copy that gets rejected by a character limit, an editor or a search engine.

Worked Step-by-Step Example

camelCase: 'eCommerceProductLaunchStrategy'
snake_case: 'e_commerce_product_launch_strategy'
kebab-case: 'e-commerce-product-launch-strategy'
