1. Engagement Metrics
When a search engine delivers a page of results to you, it can measure the success of the rankings by observing how you engage with those results. If you click the first link, then immediately hit the back button to try the second link, this indicates that you were not satisfied with the first result. Search engines seek the “long click” – where users click a result without immediately returning to the search page to try again. Taken in aggregate over millions and millions of queries each day, the engines build up a good pool of data to judge the quality of their results.
2. Machine Learning
In 2011 Google introduced the Panda update to its ranking algorithm, significantly changing the way it judged websites for quality. Google started by using human evaluators to manually rate thousands of sites, searching for low quality content. Google then incorporated machine learning to mimic the human evaluators. Once its computers could accurately predict what the humans would judge a low quality site, the algorithm was introduced across millions of sites spanning the Internet. The end result was a seismic shift that rearranged over 20% of all of Google’s search results.
3. Linking Patterns
The engines discovered early on that the link structure of the web could serve as a proxy for votes and popularity; higher quality sites and information earned more links than their less useful, lower quality peers. Today, link analysis algorithms have advanced considerably, but these principles hold true.
Both Google and Bing take page-loading speed into account in their website ranking algorithm.
Users may leave your site if they have to wait even just an extra few seconds for each page to load. That would hurt your dwell time, increase your bounce rate and reduce the number of pages viewed – all of which could hurt your SEO ranking.
There are many ways to increase page load speed, some of which include using a caching plug-ins, making sure the code is clean and streamlined, optimizing image sizes, reducing the number of plug-ins, and minimizing redirects.
“Dwell time” is the amount of time visitors spend on your website and it can affect SEO ranking.
When you provide useful content, visitors tend to stay longer on your website to consume the information and therefore increase the dwell time.
Based on this research, content between 2,000 – 2,500 words seems to rank the highest in search engine results.
Although word count doesn’t rule the SEO world – nobody will read your stuff if it’s not helpful to them – longer content does give you the opportunity to provide more value, include more keywords, incorporate more outbound links, and of course, get people to spend more time reading to increase dwell time.
Another reason to create highly useful content is that when visitors bookmark your content on Chrome, it will improve SEO ranking of your website in Google.
Even if you have a well-educated audience, they probably don’t want to be deciphering a PhD dissertation every time they visit your website and read your content. You don’t want them to give up reading your content and click away because it’s too difficult to digest.
Making your content easy to read and understand helps make it useful to your readers. Some experts also believe that Google takes readability into account when ranking web-pages.
