What is an Ideal Length for a Blog? Should it be?

According to a recent study, blogs, which appears more frequently on search engines, are between 300 to more than 1500 words long. It also says blogs of more than 1000 words are frequently picked up and shared than blogs of shorter length. I agree that this study depends more on the population of readers that share blogs on social platform like twitter. The study also said that to keep up with the word length, the writers definitely feel the pressure, and that is not a healthy option for writers. The blogging is more about sharing your thoughts and ideas freely with others, although a professional and commercial aspect is associated with most of it. Imagine, if the thought process results in a 2000 words long blog, and blogger shrink it down to make it more popular, it may end up in a different piece of work from the original. Similarly, if one produces a blog of 200 words only, he shouldn't try to stretch it to more than 1000 words, which can compromise the content and ideas. I believe that the first hand thought process or ideas should get transformed into a piece of blog. Obviously, it should be corrected for content, flow, language, and grammar. Stretching and shrinking it can be a different game, and not all the bloggers will prefer it. In scientific communications, the journals have the flexibility to publish a work under category of short communications, if the lengths of the manuscript is shorter. But, remember, they are targeting different type of readers. Similarly, different length of blogs target different kind of audiences and the content really drives this factor.  Another important aspect is the reader's perspective, where again there is a huge diversity. As a blog reader, I prefer reading a blog which is not too long, can be read in a few minutes and the content or gist of it can stay with me. The long blogs are generally read up to the first 1-3 paragraphs only in most of the cases. Nowadays, reading blogs on mobiles has also an impact on this parameter. I don't agree that there is anything like Ideal blog, it all depends on the kind of readers who are reading it. For example, readers who are looking into daily motivation will prefer a small blog which can read quickly. For them, an ideal blog will be 100-300 words. So, is it acceptable to put a general tag to all the blogs? The more appropriate thing will be to categorize the blogs, based on the labels, keywords, title, and content. Its high time the world of blogs should get organized, the way we have in any organized set-up; be it a library, supermarket, mall, or online shopping site. There is huge population of reader, who wants specific kind of reading as per their interest. To help them, we need to classify every blog into different category and there should be some database, which can help people to find blogs as per their needs and preferences.
