Link Attraction Factors: Report, Tools, API and Plugin

A few weeks ago I published my Link Attraction Factors report over on Read/WriteWeb and the response was awesome. I also made two tools: a keyword checking tool and a title checking tool.

The keyword checking tool
Enter a keyword and the tool will return data on popular stories on Digg that mentioned that keyword. The average story in my database got 299 links and this tool displays the difference between that average and the average number of links accumulated by stories using the word.

The title checking tool
Enter a title and the tool will breakdown the words and display the effect they had on the link accumulation of popular Digg stories. This tool is good for copywriters looking to find “words that word”. The scores are displayed in an easy to learn from way.

There have been a bunch of great blog posts about them, and some people have said some nice things:

I love it! Dan has developed a fascinating resource and I am sure it will only improve with time and tweaks.
Chris Garrett

I love to see people passionate about their craft who work hard to develop tools and products that help the community. Many people have created Digg tools and Dan has worked hard to create a new, unique tool of his own like his LAF tool. Simply plug-in your future Digg submission title, hit Calculate, and it will return the potential effectiveness of each word contained within your title. The keyword effectiveness is crosschecked with titles of past successful submissions. A fun tool that I’m sure many people will get a lot of use out of.

Great job, Dan! You’ve helped the industry take a huge leap towards quantifying the value of social media optimization.
-Hugo Guzman

Dan summarizes a large amount of Digg front page data to show us what categories typically get the greatest number of links. Interesting read, and I look forward to seeing other great studies from him in the future.

This is an amazing tool.

This tool is great! Will try to write better titles using this tool in the future. Thanks for your great effort.

Never one to get complacent I’ve also developed an XML API version of the title checking tool and a WordPress Plugin version of the same tool.

LAF XML API
You can access the LAF (Link Attraction Factors) database via a new XML API by sending your title through a URL (GET) variable like this:

http://www.linkattraction.com/api.php?title=this+is+a+test+title

The API will return an XML document of your results that looks like this:

<titleresults>
	<title>this is a test title</title>
	<score>-6.96%</score>
	<word>
		<name>this</name>
		<score>-5.26%</score>
	</word>
	<word>
		<name>is</name>
		<score>-0.87%</score>
	</word>
	<word>
		<name>a</name>
		<score>-0.16%</score>
	</word>
	<word>
		<name>test</name>
		<score>2.29%</score>
	</word>
	<word>
		<name>title</name>
		<score>-30.79%</score>
	</word>
</titleresults>

The average number of links is ~299, and the scores are calculated by comparing the average number of links accumulated by stories using each keyword in their titles against the average. They’re displayed in percentage format.

WP-LAF
This is a plugin for the wordpress that checks a title against the LAF (Link Attraction Factors) database. The plugin will breakdown the words in your post title and display the effect they have on link accumulation.

A plugin version of the LAF Title Check tool, it uses the XML API LAF database interface. For more information about the LAF database, read the report.

Download the plugin now.

How to install WP-LAF

  1. 1. Extract the WP-LAF folder from the zip file
  2. 2. Upload the WP-LAF folder to your the plugins directory on your server
  3. 3. Click the ‘Activate’ link for WP-LAF on your Plugins page (in the WordPress admin interface)

So go, check them out and let me know what you think.

Sneak Peak of Digg Link Acquisition Report


Above is a little sneak preview of data from a report I’m finishing up now and has been the reason my blog has been so quiet recently. (Click for a larger view).

I’ve compiled a database of over 32,000 links that made Digg’s homepage in 2007 (a little over 37,000 total went popular last year) and the number of incoming links each page has. Then I dug into the data and discovered which factors (like time and day of submission, popularity of submission, topic, and the occurrence of certain words in the title and description) lead to higher or lower average incoming links.

The graph above shows the containers stories can be listed in on Digg and how many more (or less) links the average story submitted into those containers gets compared to the average story overall.

I will be selling the report as a PDF once I’m done with it, and it will include access to a tool that allows you to enter any keyword or phrase and it will return information about that word or phrase’s effect on the average number of incoming links a story gets.

If you’d like to pre-order the report, email me with a price you think is fair, if you have a fairly popular social media/internet marketing blog and you’d like to get a free review copy when its published, email me too.

If you think of any additional factors that may influence link accumulation comment them on this post and I’ll make sure I include them in the final report.
