Testing Readability

Another post courtesy of Lorelle. This one’s not a Blogging Challenge as such, it is a test of the readability of your blog. I’m not going to go into the specifics. Lorelle has done a really good job (as usual!) of explaining so go read the post to get the full gen.

Most of the results for the tests are irrelevant when testing a blog post. This is because the Juicy Studio tester looks at the content of the whole page rather than just the relevant post. For example, I ran the test on What I did on my summer holiday, a fairly short and recent post about Theo Walcott. These were the results:

  • Total sentences 91
  • Total words 247
  • Average words per Sentence 2.71
  • Words with 1 Syllable 149
  • Words with 2 Syllables 71
  • Words with 3 Syllables 22
  • Words with 4 or more Syllables 5
  • Percentage of word with three or more syllables 10.93%
  • Average Syllables per Word 1.53
  • Gunning Fog Index 5.46
  • Flesch Reading Ease 74.95
  • Flesch-Kincaid Grade 3.48
  •  
    There is definitely not 91 sentences in that post! The three results that are most interesting are the last three – Gunning Fog Index, Flesch Reading Ease and Flesch-Kincaid Grade. The three results mean:

  • Gunning-Fog Index: An estimate of the number of school years it takes for someone to understand the content. The lower the number, the more understandable the content will be to your visitors. Results over seventeen are reported as seventeen, where seventeen is considered post-graduate level
  • Flesch Reading Ease: Represents an index number that rates the text on a 100-point scale. Higher scores means higher readability and easier comprehension. Authors are encouraged to aim for a score of approximately 60 to 70
  • Flesch-Kincaid grade level: Another test that determines the number of years of school required to read the content, like the Gunning-Fog index.
  •  
    I ran the test on five other posts, with the results as follows:

    Two Minute Silence

  • Gunning Fog Index 6.31
  • Flesch Reading Ease 74.97
  • Flesch-Kincaid Grade 4.16
  •  
    Tagging Keywords and Permalinks

  • Gunning Fog Index 5.69
  • Flesch Reading Ease 80.95
  • Flesch-Kincaid Grade 3.00
  •  
    Blog About What You Know

  • Gunning Fog Index 7.08
  • Flesch Reading Ease 78.03
  • Flesch-Kincaid Grade 4.12
  •  
    A Dissatisfied Finch

  • Gunning Fog Index 6.10
  • Flesch Reading Ease 79.01
  • Flesch-Kincaid Grade 3.72
  •  
    Kill The Nokia Tune

  • Gunning Fog Index 4.33
  • Flesch Reading Ease 86.74
  • Flesch-Kincaid Grade 2.22
  •  
    Looking at those results I am fairly happy with the readability of all of them. The Gunning Fog Index result on Blog About What You Know is a little higher as it is a more technical post about photography. Still, it’s nowhere near the 17 that would require post grad schooling to understand!

    Just for reference I ran Coldplay’s X&Y through the tester too:

  • Gunning Fog Index 4.07
  • Flesch Reading Ease 87.70
  • Flesch-Kincaid Grade 1.80
  •  
    This result gives an indication of why the song means so much to so many people!

    The tests do beg questions though:

    1. If this is a decent level for a reader, what does it say about me as the writer? That I have a natural ability to write easy to read posts, or that with my level of education (Technical to degree level) I write like a kid?

    2. While the tests are fantastic against a set scale, what do the readers of my blog think of my writing? Set scales are fantastic for measurement, but we often find that in the “real world” the opinion is much different!

    I guess the problem with such tools is that for them to work, you need to make a couple of assumptions. It’s quite cool, but I agree it does beg a whole lot of questioins.

    Aside from thew questions you’ve asked, there’s also the fact that spelling, grammar and language aren’t really a factor, as running the test on non-english blogs still gives ok results.

    [...] This morning as I was minding my own business, blog surfing I came by this post on Blog Readabilty by Cornell Finch, springing from this post by Lorelle VanFossen. Gez Lemon, owner of Juicy Studio, whose mission is to promote best practice for web developers in a fast moving industry, created Juicy Studio Readability Test to test the readability of your blog or website using a couple of complex algorithms to track how much schooling is required to able to understand all the drivel you’ve written.

    I agree that spelling and grammar don’t seem to make a difference.

    Perhaps the tester is intelligent enough to recognise non-English text though…

    I tried to visit your blog to read your article, but I think it’s broke. :(

    It was an issue with my web hosting company, I realised it when I tried to do some work on the blog.

    They’ve got it sorted out now though.
