On Valentine’s Day in 2014, love isn’t just in the air, it’s online as well.

As usual, Google Inc. (NASDAQ: GOOG) is getting into the spirit with one of its trademark doodles. On the U.S. homepage, Google’s logo has changed into a collection of clickable candy hearts. Each tells a “true story of love.” New Zealand users are treated to a different, interactive logo that actually allows them to create a customized Valentine’s Day box of chocolates.

Social media websites shared some information about love and relationships. Twitter Inc. (NYSE: TWTR) reported that users tweeted “I love you” 481 times and in 116 different languages in 2013. Israel sent love into the Twittersphere more than any other country, while the U.S. was ranked 26th.

Facebook Inc. (NASDAQ: FB), which has a lot more access to personal data, celebrated Valentine’s Day by sharing some interesting relationship statistics found by the Facebook Data Science Team. Using anonymous, aggregated data from Facebook users over the age of 21, the Facebook Data Science Team looked at users who changed their relationship status during the course of a month to determine which cities are the best and worst to find love.

The cities with the highest percentage of single people are, in following order, Detroit, Los Angeles, New York, Miami and Memphis, but the cities where people have the best chance of finding a relationship are Colorado Springs, Colo.; El Paso, Texas; Louisville, Ky.; Fort Worth, Texas; and San Antonio, Texas.

Facebook also used check-ins to create lists of Valentine’s Day restaurants for 10 U.S. cities.

Users are also finding interesting ways to express their love on social media this Valentine’s Day. To help out, Facebook released two new packs of Valentine’s-themed stickers users can send to their loved ones.

Here’s an example of a guy using Vine to ask his girlfriend to marry him. Of course, she answered on Twitter.

Actor Aaron Paul, known for playing Jesse on the AMC show “Breaking Bad,” also made a cool stop-motion animation on Vine to express his love to his wife.

Microsoft Corp. (NASDAQ: MSFT) celebrated Valentine’s Day slightly different. Instead of cute graphics or relationship stats, Microsoft decided to show how relationship councilors use Skype, which Microsoft purchased in 2011, to help troubled relationships. Not really the most uplifting of messages, but alright, Microsoft.
