30 billion.

That’s how many pins have been created on Pinterest since its launch in 2010.

And guess what? The number of pins has increased 50 percent in the last 6 months alone!

With so much content, Pinterest is working hard to make sure users can still find the content that’s most interesting to them.

Learn about Pinterest’s newest discovery features and much more in this week’s marketing news roundup.

1. Pinterest’s newest features: Guided Search and Custom Categories

Pinterest launched two new features designed to make it easier for users to search and discover the content that’s most interesting to them.

Guided Search: The new Guided Search feature, will help users search for content on the site, even when they aren’t quite sure what it is they are looking for. Similar to search engines like Google or Bing, when a user begins typing a word in the search box, Pinterest will pull in possible categories and keywords that start with the same letters.

According to Ben Silbermann, CEO of Pinterest: “Guided search will help you discover when you didn’t know how to ask for things to begin with.”

Custom Categories: The new Custom Categories feature will expand on the current list of 32 categories that are currently available within Pinterest. Now, users will be able to create sub-categories for specific topics that they are most interested in. Pinterest will then pull in content, based on the keyword you’ve chosen for the category.

Silberman explains, “If there’s something you’re interested in that isn’t encapsulated in the 32 categories, you can now search for it with keywords.”

Bottom Line: To date, Pinterest users have created 750 million boards, including 30 billion pins.

With these new features, Pinterest is helping users navigate the ever-growing amount of content that’s available on the site, and find what’s most interesting to them.

As a brand on Pinterest, this is an important reminder to make sure you’re creating boards and pins that are descriptive and include keywords that are relevant to your audience.

Provide a complete description of what you’re pinning on your board. Use the keywords that you would use on your website or in blog posts to get found. The more descriptive you are, the more likely your content will come up when someone is searching for those topics.

2. LinkedIn announces mobile photo sharing

According to LinkedIn, members who share images with their network are five times more likely to have other LinkedIn users engage with their updates.

And this week, LinkedIn announced a new tool for users to create and share photos on-the-go. With the new photo-sharing app, LinkedIn also provided ideas for how users can use the new photo-sharing app to generate engagement.

A few examples include:

  • Share a view from your desk
  • Add a professional photo to your profile
  • Show off talents
  • Share visual updates from conferences, tradeshows, and events

The new app will be rolling out to all LinkedIn users in the coming weeks.

Bottom Line: Allowing users to share photos from their mobile device is by no means a new idea for social networks. This is a feature that has been available on sites like Facebook, Twitter, and Google+ for quite some time.

For other networks, adding the ability to share photos from wherever you are, completely changed the way people use these channels for personal and professional use.

As a small business on LinkedIn, the ability to share behind-the-scenes photos could be an opportunity to think differently about how you’re using the site to build relationships and tell your business’s story.

3. Facebook launches Nearby Friends feature to find friends in your area

Facebook has begun rolling out a new opt-in feature called Nearby Friends.

The new feature allows Facebook users to see when friends are in the area, and can share their exact location with them for a limited a time.

If you’ve opted-in to use the feature, Facebook will show you a list of friends who are in the area, and will give notifications when other users share their location. When sharing your location with a Facebook friend, you can include a 40-character message about what you’re doing, which Facebook hopes will encourage friends to meet-up offline.

(Note: This change will impact personal profiles, not Facebook Pages.)

Bottom Line: Nearby Friends  provides another example of how Facebook is changing the way users interact and share information with each other online.

Here’s how Facebook explains the new feature:

When Nearby Friends is on, you can see when your friends are traveling if they’re also using this feature and sharing with you. You’ll be able to see the city or neighborhood they are in, including on their profile. When you see a friend visiting a place you’ve been, it’s the perfect opportunity to send a recommendation for a great restaurant. You can also make last-minute plans to meet up with a friend who happens to be in the same place you’re headed to.

This could prove to be a big win for local businesses, especially those with brick and mortar locations. Now, Facebook users will not only have the option to check-in at your business, but will also be able to share their location and use the new feature to connect with friends.

This is another example of why it’s so important to use a Facebook  Page, rather than a Facebook Profile to market your business. You’ll also want to make sure you’re choosing the right type of Page, so that people can find and check-in at your location.
