Jan 27, 2012   //   by Kristi Hines   //   SEO Blog, SEO tools  //  14 Comments

Have you ever visited a website and were curious about what they were running on it, such as the platform, analytics, or add-ons? Have you ever wondered how many other people are using the same website components as you do? Do you want a quick SEO profile of the site as well? If so, then you need to visit BuiltWith.com.

Learn What Technology Any Website Uses

Technology Profile

There are three ways to find out technology a particular website is using. First off, you can visit the BuiltWith.com homepage and enter the domain name in the search box. Next, you can just enter http://builtwith.com/domain.com into your browser and change domain.com to the domain of the site you wish to view. Or you can download the Chrome Extension and click on the extension to see a popup with the website’s technology profile.

On the website’s profile page, you will find the following information (when applicable).

  • Server Information – This doesn’t tell you where a site is hosted, but tells you the type of web server the site is hosted on.
  • Content Management Systems – This will tell you if the website is using WordPress, Joomla, or a similar CMS.
  • Ecommerce – This will tell you if the website is using an Ecommerce system like E-junkie or other shopping cart software.
  • Frameworks – This will tell you the programming framework of the website. For WordPress, it will commonly be PHP.
  • Advertising – This will tell you what advertising systems are being used on a website such as Google AdSense and some affiliate networks.
  • Analytics and Tracking – This will tell you if a site uses Google Analytics, StatCoutner, or similar analytics system. Aweber’s mailing list code sometimes pops up into this area too.
  • JavaScript Libraries – This will tell you about the different JavaScript coding libraries called in the website’s coding.
  • Audio / Video – This will tell you about any technology such as Vimeo, YouTube, or other media found on the website.
  • Widgets – This will tell you about different widgets and add-ons a website is using, including social sharing buttons. It will pull information about some WordPress plugins, but most will just be lumped under WordPress Plugins.
  • Aggregation Functionality – This will tell you about the RSS and pingback functionality of a site, including whether it uses Feedburner.
  • Document Information & Encoding – This will tell you more about the website’s coding, like if it uses HTML, CSS, etc.

Alternatively, you can visit theTechnology Trends page and see the top technology used across the Internet. For example, if you clicked on WordPress, you would see the following.

SEO Profile

If you want to check out a website’s SEO information, click on the SEO Profile tab. This will give you a little analysis of basic SEO elements such as your title tag, meta description, H1 heading tag, common keywords (as shown in the pie chart above), image ALT tags, website speed, and social bookmarking stats on Facebook & Delicious. It also gives you an overall score plus a score of where your website ranks compared to others. Apparently 57% is a good score if 97% of other websites score below that!

    You don’t know how long I’ve needed something like this.

    You always come up with the most useful stuff, and that’s why I love having you write for my blog! πŸ™‚

    This is a great tool to get information of a site. I always used Alexa most of the time but it lacks some of the information i need like what framework and CMS the site is using. This comes in handy when i want learn more of my competitors. Thanks for sharing this site Kristi.

  • This tool is very informational. It is interesting to see what is running on other websites, and also can help me to determine everything that is running on mine. It could help eliminate some items that I may not need to run.

    Is this service free? If so, pretty cool!

  • Ray says:

    It amazes me the things like these we have available now. Many totally free. I did a quick check with the builtwith site you mentioned. It’s hard to imagine it knows that much about a site in a mater of seconds. We sure didn’t have all these kinds of things when I first got started in the online world. Makes me wonder what we will have in 5-10 years from now.

      I think it’s easy to pull because of the common coding required by each technology, like WordPress usually has folder structure (wp-content/themes/theme/style.css) which will be in the HTML code of any site using WordPress. πŸ™‚
