Overview
A knol is an introductory article about a specific subject. To write a successful knol, focus on the first things a reader would want to know about your topic. Remember that knols are openly available online, so you should aim to write for the broadest possible audience. For example, it’s best to avoid jargon and explain technical terms in straightforward language.Length
There’s no ideal length for a knol, but as a general rule a good knol will be longer than a typical web page. Because knols are meant for readers who want more detail on a subject, they should be more in-depth than most web content. That said, be concise in your writing. Readers appreciate getting to the point no matter what type of information they’re looking for.Tone
Knols aren’t blogs, and should avoid the informal conversational style common in blog entries. Use a more formal tone. Think of your knol as a statement more than as an ongoing conversation. A good tone to aim for would be similar to that of a textbook or a pamphlet: clinical and informative.Dos and Don'ts
Do...
- Voice your opinion
- Think about how to get your readers involved in your topic
- Provide references, ask for reviews and display your credentials
- Focus on communicating clearly
- Bring your topic to life.
Since knol authors receive attribution, knols are a great forum for expressing your opinions. Present the facts and argue your case. Readers can decide what’s valuable from your writing.
Knol offers a simple and powerful way for authors to interact with readers, which we call "moderated collaboration." With moderated collaboration, you no longer have to rely solely on ratings and long strings of reader comments to improve your content. Now, your readers can edit your knols directly, making it easier to collaborate. At the same time you stay in control, accepting or rejecting any suggested edits before they’re published and become visible to readers. Moderated collaboration is great for things like soliciting feedback, sharing partial data and building collective lists. We encourage you to think about how to use the feature in your knols.
Also, be sure to check the comments to your knols regularly, and update content as needed. Addressing reader feedback will help improve your knols' ratings and relevance.
References, credentials and positive reviews can help you gain the confidence of your readers. Use your bio to tell readers why they should trust your opinion on a given topic, and reference other works that informed your thinking. If you know of good resources on your topic, you can link to them from within your article to make it easy for readers to learn more.
If possible, ask other experts to write reviews of your knols. A positive review can show that your opinion is respected by others who are knowledgeable in your field.
Use headings to divide sections. Use lists and formatting to allow users to scan material quickly. A well-organized knol will be easier to read and engage more readers. Be sure to choose a relevant title for your article. Most search engines will give more importance to your knol title and subtitle, so a knol with a clear and informative title will have a head start when it comes to attracting readers.
Insert relevant images to make your knol visually appealing. Use videos or slide-shows to bring your topic to life.
- Follow the rules
The Knol Terms of Service Agreement and Content Policy are in place to help ensure a good experience for all users and compliance with applicable laws. Please keep your knols in good taste. Don’t include spam or malware in your knols, and make sure to follow all copyright and other applicable laws.
Don'ts...
- Write a blog
Blogs are great for quickly and easily getting your latest writing in front of readers. Knols are better for when you want to write an authoritative article on a single topic. The tone should be more formal than that of a typical blog post. In addition, while it's easy to update your knols’ content to keep them fresh, knols aren't designed for continuously posting new content or threading. Recently mastered the process of fixing a leaky toilet, but don't want to write a blog about the weeks you spent repairing your bathroom? In that case, write a knol offering a step-by-step guide.
- Post advertisements
Teasers and sales pitches may work on the back of a book when readers can preview the content, but a Knol without real information will only frustrate readers and hurt an author's reputation. Make sure your knols include substantive content in order to build your reputation and encourage readers to come back for more.
On occasions, Google will take down knols which violate our Content Policy. The most common problems occur under this clause: "There are some commercial uses we don’t allow. We don’t allow pages that have the primary purpose of redirecting visitors, acting as a bridge page, or driving traffic to another website. We also don’t allow Knol pages that have the primary purpose of profiting from displaying ads from any publisher network, such as pages created with little or no unique content that exist only to display ads."
- Write for machines
Some authors are concerned about specifically including keywords so that search engines will index and return their pages for specific results. We recommend that you always write for humans first, not for machines. If there are keywords you specifically care about, let them occur in natural text, reader-friendly ways in the title, subtitle or summary areas of the document. Documents should not engage in keyword stuffing or other practices in violation of our Content Policy.

"Length" section
Thank you for the feedback. We don't have specific guidance for word counts. We don't even display word-count at this time.
Just an approximate estimate, I would say 1500 - 10000 is a good word count range for knols. Shorter articles (500-1000 words or 1-2 online pages) are probably of insufficient depth to be good knols.) Longer articles might be better broken up into separate cross-linked articles. These are just estimates, not hard-and-fast rules.

I did a study of the top rated Knol recently and discovered an average word length of about 4,200. I have contributed about 30 Knols and without writing with a word count in mind, I end up at around the 3,500 word mark on average, and 13 of those Knols currently rank in the top 1%. So, my suggestion is to write between 3,000 and 4,000 words as a ballpark figure or until you believe you have fully answered the promise contained in your title. Peter

I can see some of the medical and scientific articles growing into small books. And I like this idea, it's much more energizing than Wikipedia. In fact, a new format could emerge: the Summary, targeted to around 3,000 words or less; and the Thesis, with unlimited word count.

80% of my Knols are ranked on Page 1 of Google & Yahoo
There were, No clever 'smoke & mirror' SEO strategies, No clever article marketing strategies, No link farming ... just good old fashioned writing that gives my target readers the information they want, in a way they want it.
For the details on how you could achieve the same result, see my knol below ...

Congratulations on achieving a degree of initial success as a Knol author.
I would observe that many of Peter's pages follow best practices of knol / internet authorship, and would encourage other knol authors to learn from him.

Writing about geographic areas pertaining to real estate
I do web marketing for real estate agents, and I'm constantly writing content about cities, neighborhoods, home builders and other geo-graphic and realty related topics.
Would it be prudent to write a Knol about a specific area from one perspective, say residential real estate, as opposed to addressing an area in its entirety?
Sincerely,
Jenna Ryan

Regarding your specific question, the title of a knol should say what it is about. Don't title your knol "San Diego" if it is about "Residential Real Estate in San Diego."
Here is our content policy:

See in particular the guidelines on Commercial Content. We encourage content which is unique and not merely a duplicate of what is already available upon the web.
