How to Use Web Annotations to Build a Swipe File for Copywriting

A swipe file is a collection of copy that works: headlines, emails, landing pages, product descriptions and ads you can learn from. Copywriters have kept them for decades. The web makes collecting easy; the hard part is remembering why each example caught your eye.

What to collect

• Headlines that made you click.
• Opening lines that pulled you in.
• Landing pages with clear offers.
• Calls to action beyond "Submit."
• Product descriptions that make features feel concrete.
• Emails you actually read to the end.
• Error messages and microcopy with personality.

Note why it works

An example without a note is just a bookmark. For each one, write a sentence on what makes it effective:

• "Specific number in the headline."
• "Speaks to the reader's worry before the product."
• "Turns a feature into a result."
• "Removes risk with a clear guarantee."

Annotate on the page

Sticky Notes Anywhere lets you leave notes directly on the page next to the copy. Each note is saved for that page, and the side panel lists all your notes with search, so tagging notes "HEADLINE" or "CTA" lets you pull up every example of one type. You can export everything to a backup file.

An example entry

A note on a meal-kit landing page might read: "HEADLINE. Leads with time saved ('Dinner in 20 minutes') rather than food. Price per serving shown right under the button. Guarantee repeated next to the sign-up form." Months later, that note tells you exactly what to borrow.

Save a copy

Websites change copy often, and campaigns end. Take a screenshot of anything you want to keep, and check whether the Internet Archive has saved the page.

Organize by use

Group examples by what you'll need them for: headlines, emails, sales pages, onboarding. When you sit down to write a launch email, you can review a dozen good ones in minutes.

Using a swipe file well

• Study structure: how a page moves from problem to solution to proof to offer.
• Borrow techniques, not words.
• Adapt to your audience: what works for one product may not suit another.
• Don't copy: lifting copy is plagiarism and may infringe copyright. It also won't sound like your brand.

Keep it fresh

Add a few examples a week and remove ones you never look at. A small, well-annotated file is more useful than thousands of saved pages.
