We decided to do this now because our two-year contract with Microsoft was up for renewal. We did an evaluation and figured out a way to draw a large number of pushpins on GMaps very quickly. When we went with VE in 2006, GMaps was faster out of the box but slower once we started drawing on it, especially on IE6.

We like a lot of things about going with Google Maps:

• Fast downloads
• Fast drawing speeds
• Broad browser support
• High-resolution Geoeye-1 satellite images

We don’t like that we can no longer embed Bird’s Eye views on our site and that 3 developers spent four weeks to do the switch instead of adding more features. Plus, Redfin has had a very good relationship with the Microsoft Virtual Earth team, which we’ll miss. We’d like to give special thanks to Sujatha, the Microsoft PM who answered our e-mails, calls, and random entreaties with the utmost of professionalism and speed. We really only have good things to say about VE. Anyone looking to build a map-based Web 2.0 site has two solid choices.

In the end, it was speed, speed, speed that convinced us to switch. In our worst case scenario of 500 pushpins on the map in IE6, GMaps is 385% faster.

“Every millisecond counts” is a “Googley” UX design principle that we remember from Marissa Mayer’s evangelism of speed and that we strongly believe in (see here, here, and here). Users who come to Redfin’s site now should see maps load and render just a little bit quicker, which makes us feel a little Googley inside.

That’s it! Happy holidays from Redfin Engineering. You won’t hear from us until February, as we’re already working on a major release that will take a little more time. But it’ll be worth it. For those of you using the site, can you notice a performance difference? Leave a comment and let us know!

Bonus for developers: read about our experience switching from Virtual Earth to Google Maps. 

In an effort to improve our forms, ace product manager Matt Goyer bought a book on usability for one of his young charges, Jim Lamb. But when Jim started reading the book, he found that one of the forms the book was supposed to help us improve was already in the book:

On the left side of the page pictured here, you’ll see Redfin’s Offer Wizard.

When Matt came into my office to show it to me, I could only think of Groucho Marx’s rejection of any club that would accept him as a member. “Wow,” I thought. “It’s time to get Jim another book.”

(In fact, the book looks fantastic. Many thanks to author Luke Wroblewski for including us!)

When we released the latest version of Redfin.com, we ran our first message this space announcing our new neighborhood pages. The text was: “New! Pricing trends for every neighborhood. And more.” With “neighborhood,” we linked to a respective city page for each market. With “more,” we linked to the Redfin blog post about the features of the latest release.

We were worried that placing an announcement across the top of the map would annoy people searching for homes. We ran the message for a week and tracked how often people dismissed the box and clicked-through to the links.

Click-Through Rate
The total click-through rate (CTR) for the message box was high (1.95%), higher than any other message location on Redfin.com. For the “neighborhood” anchor text, Seattle (2.93%) had the highest CTR and Southern California (1.35%) the lowest. The anchor text linking to the blog post had a CTR of 0.15%, which is not surprising given that it was the second link in the message.

Dismissal Rate
The dismissal rate for the message box was 1.50%. DC had the highest rate (1.86%) and Boston had the lowest (1.08%). The dismissal rate was lower than we expected. The low rate is likely due to the fact that users: 1) weren’t seeing the box; 2) were unable to find the X to close the box; or 3) didn’t mind having the box on the screen.

We’re thinking about trying out a few different treatments for the box- different colors and different length messages to test how the dismissal and click-through rates change.

What about you? Did you notice the message? Did you leave it open or click it away?

Before launching the feature we debated what the top service would be. Glenn, voted for Delicious, I voted for Facebook. In fact I thought Facebook would win by a long shot which is why we used the text “Share on Facebook” instead of something more generic like “Share on…”

Curious who won the bet we used the AddThis analytics feature to settle up. Here’s a breakdown of how many times the various services have been used:

Of course, maybe the fact that the link specifically calls out Facebook is the reason it is the leading bookmarking service .

Here’s a breakdown by day.

In our next release we’ll add a Facebook icon in front of the link to increase its discoverability.

Big thanks to Dan, for pushing us to use AddThis.com, instead of adding only a Share on Facebook link.

When we re-designed our website in April one of the changes we made was hiding the search options. The reasoning behind this controversial design was that since users spend most of their time navigating the map and only occasionally change the number of beds or square footage that they’re looking for, we should make the map as large as possible and move the search options to an overlay. The overlay then only appears when you give focus to the search input box or click a widget.

Initially to display the search overlay pictured above users would need to click the link ‘Filter Search’:

However, we heard occasional stories of users not knowing they could search on number of beds or price. So our next design was to include a drop down widget besides the search button. This is reminiscent of what many Windows applications do or what Facebook does.

But still we heard stories of users not knowing they could change their search options. With our next release we’re looking at combining both the link and drop down widget approachs by moving the drop down widget and changing the name on the link to hint at what it enables you to change:

Unfortunately a number of co-workers stormed into my office yesterday, criticized the design and called me names. If I were to pass you the Redfin Search Product Manager baton how would you solve this discoverability problem? Feedback welcome but Photoshop submissions preferred . To sweeten the pot we’re offering $250 if we use your submission. However, if you have a winning submission the real question is, why haven’t you applied for our interaction designer position yet?

And with that I’m off to Whistler. Happy Thanksgiving!

We only get one shot at the explanation because returning visitors see a view of our map as they left it on their last visit. Many are so thunderstruck by Redfin’s search superpowers that they never realize we have to make a living buying and selling homes.

When we surveyed our customers about what they wanted to see on the home page 58% asked for an explanation of our commission refund, 47% for an overview of our company, and 45% for a step-by-step guide to the process. But you should just say what you want: even though this blog is by and for people at an absurd remove from reality, please don’t feel like you have to channel anyone normal. It never works.

Thanks to Savan Kong, Jason Wu, Michael Young, Matt Goyer, Jeff Yee, Marc Singer, Dana Irming, Bryan Selner, Leo Shklovskii and many others for their input so far. And thanks to everybody else for your feedback now…

We’ll also post a link to Redfin Forums, too.

Scroll down a bit and look for the above box on the left-hand side of the listing detail page, usually below the “Sales History” box. Note: clicking on the links will open another window, leaving your Redfin search intact on the original page.

I checked out my own Zip Code (98109 in the Queen Anne area of Seattle) and immediately homed in on education level and school test scores. I think I secretly wanted to know if my neighbors could hold their own on the new hot game show where “smart, educated” adults pit themselves against a handful of Golden State fifth-graders. I learned some fascinating conversation topics for my next cocktail party or playground chat with a neighborhood fifth-grader … I’ll crush them with my local knowledge.

A few things I learned about my area (which you can discover about your current or prospective one too!):

1. The median age is 36.28, not 9 (the average age of a fifth-grader).
2. Summer break comes at just the right time. July’s average high is 74 degrees!
3. The bachelor-of-arts crowd dominates at 31.2 percent, beating the fifth-graders at only 1.4 percent.
   
4. We’re under average for murders, but we must have easy-to-steal cars because the motor vehicle theft rate is more than 300 times the national average.
   
5. Earthquakes are the biggest weather risk – eek! A reminder for Seattleites to go to the mailbox and vote … tunnel, viaduct, both or neither?! sigh
   
6. Another cool thing you can do is compare cost of living, down to how much more or less your clothes will cost.
   
7. Out of 15,395 people, there are only 63 fifth-graders. Majority rules!

Warning: the comparison feature is addictive! I looked at a couple different cities I’ve lived in:

1. If I wanted to move back to Redondo Beach, Calif., I’d need to get an 11 percent raise to maintain my “Bud Light” lifestyle.
2. I could go back to Pullman, Wash. and get by with 37 percent less money (a round of drinks at the Coug on me!).

We also added open house information, when available. In the next couple months, they’ll be easier to find, but right now you will see the information under the house photo on the listing detail page.

Look for the above box under the listing’s main photo

An added bonus for you trivia hounds out there (real questions from Are You Smarter Than a Fifth-Grader? – no cheating!):

1. Which U.S. border is longer – Canada or Mexico?
2. Name the ship the pilgrims sailed from Plymouth, England to the Plymouth colony in America in 1620.
3. How many teaspoons are in a tablespoon?
4. How many U.S. states border the Pacific Ocean?
5. If you mix equal amounts of red and yellow paint, what color do you get?
