Get-Free-PR-AppPR is one of the best sources of free traffic. And finding ways to get users cost-efficiently is critically important if you're looking to build a viable business model.

But for a new startup, it's not as easy as it sounds. There are thousands of apps launching each month, and not everyone gets coverage.

The good news is; a good old hustle can get you much further than waiting for things to just happen. Here are some tips.

1. Nail Your One Sentence Pitch

Journalists are pitched every day. They get hundreds of emails, they're tweeted at and approached in person at conferences and events. And then they have to spend their days reading, researching and writing.

Frankly, no one is going to read your lengthy emails and listen to complex pitches explaining every aspect of your app. If you can't convey your idea in a single sentence and make it attractive, you're done.

So nail your one sentence pitch and make it powerful, clear and concise. Use the language of a 6th grader, avoid buzzwords, superlatives, and technical terms. A great template to follow is the one designed by Adeo Ressi.

2. Have Some News

To land a the name of your app you need to offer some news. The reality is that most apps are particularly unique or breakthrough, so make sure you have something newsworthy to offer. For example:

•       Launch of your app, product or new feature

•       Closing an investment round

•       Announcement of high-profile partnership

•       Reaching an important milestone

•       Response to current/trending events

•       Release of interesting data or study

PR marketing is not a one-off event. It's rather a continuous process or an effort that should become a habit. So every time you have some news to offer, reach out. Over time, you'll develop connections, and things will get easier.

3. Make a Hitlist of Relevant Journalists

Most founders/marketers assume they should just pitch the editor-in-chief. In reality, major publications have journalists that specialize in particular areas such as hardware, mobile, productivity, food, enterprise, etc.

Aside from fro finding the relevant person, look up the preferred pitching method for given publication. For example, stories for Mashable should be pitched to news@mashable.com.

The best way to start is using Google to find articles related to your market and just copy the name of the journalist to a spreadsheet. Even better tool is Buzzsumo.

4. Do Your Research

Before you send out any emails, make sure you know something about the journalists you're going to pitch so you can establish rapport and make it more engaging.

As for finding emails use PressFriedly and JustReachOut. Both tools make this aspect of PE marketing incredibly easy. To track what happens your emails, Sidekick from Hubspot is another great tool.
