Compendium Blogware's post editor features a small widget known as the Keyword Strength Meter (referred to by the development team simply as the "KSM"). It's a display that gives the author a quick indication of the current keyword usage in your post. Starting at a bright red, the appearance will transition to green as keyword phrases are added to the post.

I wrote an introductory post about the KSM soon after it went live in the summer of 2008, and since then it has gone through many changes.

There were revisions to make sure that it was able to compute the score on the fly without imposing too much overhead the host browser.
When we switched editor technologies at the beginning of 2009, we made the code more modular so that it wouldn't be as tightly coupled to the editor that it was monitoring.
Also during the editor revamp, we changed the display to emphasize that the meter is a qualitative measure.
This past summer, after introducing a new moderation dashboard for network administrators, we added a keyword strength meter to the post preview so that network administrators could view the value.

One thing that hasn't changed as our user base has grown is the intense affinity that users have had for the widget. From Sales and Client Success, I have heard stories of users who endured great frustration because they couldn't make their posts turn the right shade of green. I've also heard of network administrators who have rejected posts because they weren't green enough.

As the developer of the original implementation of the KSM and the designer of its scoring algorithm, I think it's important for content authors and network administrators to have an awareness of what the meter measures so that it can be used effectively. I'll also talk about what it can't do for you.

The meter looks at three things in determining its score:

Does the post contain any keyword phrases?
Are the same phrases being used over and over, or is there a variety of keywords being chosen?
Are too many keywords being used relative to the length of the post?

These measures are combined in a way that simultaneously rewards keyword usage and penalizes keyword stuffing, a practice that Compendium discourages because it runs counter to what we are trying to help our clients achieve.

Keyword usage is but one piece of a successful corporate blogging program. Other significant factors include:

Creating Content Steadily -- The primary axis of content organization within a single blog is time. Newer content appears on the lead pages. Older content takes more mouse clicks to reach via pagination. Assuming that search ranking algorithms place greater emphasis pages closer to the root of a URL hierarchy, the new content is what gets the greatest weight. A steady stream of new content ensures that indexers know you're alive and relevant.
Choosing Topics Relevant to the Customer -- If sales of your products fluctuate over time and change of season, you'll probably want to adjust the emphasis of your posts accordingly. Sometimes the keywords you chose initially for your blogging program don't take these topics into account. If you focus too narrowly on the original keywords, you'll wind up creating posts that miss opportunities to convert.
Being Real by Letting the Rank and File be Themselves -- Our application makes it easy for organizations to add new user accounts for blogging. We do this to encourage our clients to a wide variety of employees blogging. Packing the blogging team with people exclusively from the Public Relations team runs the risk of making blog content read like those newsletter inserts that come with utility bills. Do you read those things? I didn't think so. Overemphasis on using exact keyword phrases in every post also runs the danger of making their usage look forced, which can be spammy looking.

What's common to all of these points? They cannot be measured by the KSM.

The content creation time line graphs on the network administrator's dashboard can help keep an eye on frequency. The content ideas panel on the user dashboard can provide timely reading for new ideas. Producing real content requires human beings with inspiration and knowledge of the customer's needs. No computer can replace that.

The bottom line? Use the KSM as part of a comprehensive strategy to make sure that keywords are being used in reasonable measure. Treat it as a rough guide, not an all-knowing oracle.
