A suite of word counters, keyword counters and readability analysis for your blog.
The stats caching notice seems stuck
The word count/readability calculation isn't accurate
Word Stats uses simple algorithms (but more elaborate than the PHP word counter). For fairly ordinary English texts they will closely match human counting. The margin of error will be greater for short pieces, text with complex punctuation or in other languages, but they should be still good indicators.
Some HTML/shortcode words are being counted as keywords
Some cases are still not filtered out. Report them in the plugin support forum or via email.
This plugin makes my site slow
Some of the plugin's tasks can be a bit intensive, specially on large blogs. Try disabling counting for unpublished posts, and live stats when you don't need them. Our resources are limited, for now we are working on features rather than optimization.
Some common words show as keywords, even though the setting to exclude common words is activated
The built in lists only exclude some of the most common words. Performing many matches with regular expressions can be very slow.
Why the live counters seem to lag?
The calculations are refreshed every few seconds.
Are the ignored keywords counted in the total words?
Yes. They are ignored only for keyword counts.
Do the indexes really reflect how easy is the text?
They try to reflect how easy the text is to read. You can write an article about relativity in simple English and it will be rated as low level.
What do the readability number mean?
For ARI and CLI, they are the U.S. grade level of the text. Roughly, grade level 1 corresponds to ages 6-8, grade 8 to 14 years old, grade 12 to 17 years old.
Each index uses a different algorithm:
Check http://en.wikipedia.org/wiki/Readability_test for more information.
Why other common tests aren't included?
These three indexes don't rely on syllable counting, which is a bit more complicated and language dependent.
The stats page timed out.
Try selecting a shorter period, disabling the setting to count drafts and pending posts, disabling the setting to ignore common words or shortening your list of ignored keywords.
