Search Engine Optimisation (SEO) is just about keywords and links! That's a common mistake made my most new website owners. It is very easy to be drawn into a tunnel view vision of SEO, the reality is that a good SEO, spelling, grammer and punctuation are key SEO requirements. That's all true but, humans are humans, they makes mistakes. Spelling mistakes or typos as they are now commonly called, are perhaps humanaties biggest guilty secret. No one likes to admit they have mispelled a word, but the truth is we have all made spelling mistakes and do so each day.
So, when publishing a document is always important to spell a word correctly, correct grammar, punctuation and spelling are key for a solid user experience. It means more time on site, reduces bounce rate as well as adding to the over quality of your website. but, if humans make mistakes, and search engines work by matching user keywords and keyphrases to web content how do spelling mistakes work, let's look as some background information first.
Let's take this website, icalculator.com as an example. iCalculator provides a suite of free online calculators covering many different markets and disciplines. The key element across all of those is the word calculator, so calculator is a pretty important keyword in iCalculators SEO Strategy.

First, lets consider how the human braim works:
Aoccdrnig to rseearch at an Elingsh uinervtisy, it deosn't mttaer in waht oredr the ltteers in a wrod are, the olny iprmoatnt tihng is that the frist and lsat ltteer is at the rghit pclae. The rset can be a toatl mses and you can sitll raed it wouthit a porbelm. Tihs is bcuseae we do not raed ervey lteter by it slef but the wrod as a wlohe.
So, the human brain can process words in pretty much any order, this takes a little more time if the word is wrong. It is interesting that those who suffering from dyslexia can often write in this way, producing the same word, with the correct letters, in different orders each time the individual writes it. An interesting point that highlights how the human brain works on a code like mathematical flow (humans by design?). We won't discuss that particular thought at the moment, lets focus on the fact that i is therefore feasible for a user to enter a keyword in absolutely any order.
With that interesting (and somewhat scary) fact, the next question is how many variants of a word can there be in all the letters must be present but in different orders. If you are clever enough or perhaps remember far back enough to scroll, you will know that the way to calculate this is with Combinations and Permutations. To clarify, in mathematics:
So, a group of schoolchildren, standing in height order os a Permutation. If however we shuffle the same children around, the group still exists but it is no longer in order, that group is now a Combination.
Let's return to our keyword example, calculator. We now know that the word calculator is a Permutation (a group of letters than exists in an order), however we also know that the letters within that word could exist in any given order. As with all great Math possibilities, there is a mean of calculating Permutations, though in reality, we are calculating the number of combinations (as there can only be one permutation of a word, I know that as I remember being shouted at at school for failing spelling tests). To calculate the number of combinations:
Below are 1,000 different combinations of the word calculator, you would have to refresh this page over 10 million times to see all combinations of the word calculator (please note the below is random, you will see a different 1000 spelling of the word calculator each time you refresh this page, try it a few times and see. If you really want to see them all, try here, it will only take you 400,000 refreshes minimum to see them all then).. We would disagree with the research from the English University here somewhat, if you glance across those various spelling of the word calculator not all are immediately readable as the word calculator, even with the knowledge that this is the word written. You will need to scroll by the 1000 calculators to keep reading!

that. The good news is there is an answer, the bad news is that there are more than 10 billion. The 10 billion figure we calculated is purely based on a typo where the user enters all of the letters in the word calculator. The trouble is, the second most common mistake beyond misspellings is missing letters, this problem then amplifies if we consider that people can miss a letter from a keyword and also write the word in a different combination.
Lets look at another example of misspelling applied against our combination scenario. In this example we have used the following misspelling of the word calculator (calculatr, calculaor, calculato, calulater, calcuator, caulator, caluclator, calcualtor, calculaotr, calcula, claculator, calcutor, couculater, calcultor, cauculator, coculater, couculator, caclulator, calculatir, calulator, calculatoe, calcu, calc, caculater, calculatro, caulater, caluculator, calculatore) and provided a thousand examples of those misspellings. once again, refreshing the page will generate new variants of the misspelled word calculator, this time with omitted letters.

In our simple example with one keyword 'Calculator' we have encouraged of 100 trillion possible ways of a users entering the word calculator. The good news is that most search engines like Google Calculate and allow for user anomalies. Then, when they identify a close match to a misspelt word like calculatr instead of calculator, they print a message displaying options to the users (e.g. did you mean calculatr? or did you mean calculator). So, with a breath of relief you can carry on, focusing on the quality of your web content, ensuring that spelling and structure are correct and the search engines have your back. The important lesson here is to understand that SEO messages and advice often conflict, at the end of the day it is good, quality content that rules the web. Publishers focus on content, search engines focus on the trillions of variants, making sense of the nonsense that humans enter into search engines.
