16 Best Readability Checkers To Improve SEO Content

Have you ever tried to read something only to be put off by its difficulty? It happens to everyone, even the best educated and well-read people. Personally, I’ve tried to tackle “Moby-Dick” on three separate occasions, only to abandon it not long after the Pequod sets out on its ill-fated voyage. Despite being acclaimed as one of, if not the, best American novel, it’s just too dense to be an enjoyable read for me. And it’s not just novels that put people off when they’re difficult to read and understand – webpages that are poorly written, wordy, or have other readability issues are often quickly abandoned by visitors. And let’s not forget search engines love a well-written and well-structured copy. Quality content is still the name of the game, and it’s hard to rank highly without it. While dwell time is not a direct Google ranking factor, alongside click-through and bounce rate, it does offer a good metric for tracking the health of a webpage. And, of course, difficult-to-read texts will drive visitors away before they can take action on your page. So, as an SEO professional, you need to be aware of your copy’s readability and actively take steps to increase it. There are a lot of factors that go into how easy it is to consume written information on a webpage, including the font, layout, and color schemes, but for this piece, we’re going to focus on just the copy. What Makes Good Readability? Readability is based on many factors, including words per sentence and the length and difficulty of the words used. Words with higher syllable counts are generally more challenging to read than their shorter synonyms. For example, “went” is considered easier to read than “progressed” or “proceeded.” The most common measurement for readability in English is the Flesch-Kincaid test, which is two tests: one measuring reading ease and one measuring grade level. For reading ease, the higher the score, the easier it is to read. Grade level indicates which level of education is required to understand it. So, you’ve run a check, and it came back with poor scores. What do you do? You can go through it manually and identify places where your content gets bogged down, splitting sentences, swapping longer words for easier-to-understand synonyms, and changing passive constructions to active ones. Or you can put technology to work for you. 16 Tools To Improve Your Readability 1. Microsoft Word Editor If you’re already somewhat familiar with Flesch-Kincaid scores, there’s a good chance it’s because of Microsoft Word. Reading ease is included in the features of the popular word processing software, and it’s a great way to get a good overview of how your piece reads. From the Review tab, click on Spelling and Grammar. After completing the spellcheck, you’ll be able to view Document stats. Under the Readability section, you’ll get stats for reading ease, grade level, and passive sentences. This feature comes free with the software, so if you’re using Word, you should take advantage of it. If you’re not using Word, don’t worry – there are still quite a few good tools you can use to check readability stats. Read on to learn about them. 2. Readable Readability Tools Readable is “the world’s most powerful readability scoring tool.” It offers many features, including functionality specifically designed for websites. Rather than using the Flesh-Kincaid score, it has its standards, which assign a grade (A through E) to your text. It also provides reach metrics to help you understand what percentage of your audience can understand the content. Its website readability tool scans, scores, and continually monitors the content of your website, including headers, footers, and non-content text. It also allows you to check keyword density to help you avoid getting dinged by Google for keyword stuffing. Using Readable requires a subscription.
