Really, in the world of the web, slow speed kills. And most people only think about the length of time it takes a website to load when it is taking eons to show up. For static sites, meeting the magic four second page load time isn’t too hard, but for sites with lots of “dynamic content” (fancy menus and whatnot) and maps, it becomes sort of a trick.
Many (most?) fancy real estate search sites are plagued by slow load times – see the real estate 2.x person’s site reviews to see scathing analyses of how long it takes to for many sites to load. In light of this, we took great pains to make our site both feel and be speedy and, if I don’t say so, I think we’ve been pretty successful. On my old-ish computer, the Seattle real estate page typically loads in under 10 seconds (we could still do better on this!) and house detail and nearby pages typically load in under 3 seconds.
One of the tricks we employ is we don’t actually shuffle visitors from a complete page to a completely new page, which means we don’t have to reload the time-consuming Google Map or any of the stuff on the sidebar. Instead, we load little subpages within the site using AJAX (which is, I believe, a dumb acronym). When you click to see the details for a house, we only load up those details and leave the side and top of the site alone and intact. When you click back to the map tab, it’s already there waiting for you because it was just hiding behind the house information.
There are some other tricks that are much more technical: before we launched in December we did a bunch of optimization to cut down the time it takes our database (with over 30,000 western Washington properties currently for sale) to find and spit out the houses that match each search. Currently it it returns the ‘shacks’ that match your search within a second of you dragging the map around – the rest of your wait is the time it takes to actually send and display that information on your screen.
The dynamic updating introduces a can of worms of it’s own, including longer development time, but we think the tradeoffs were entirely worth it.
This is the first in a series of “Behind the Shack” themed posts. If you are especially interested in one aspect of ShackPrices.com, let me know and I’ll try to write about it!
