The dimension of Search Engine Optimization is massive with many diverse elements that we need to stress in order to properly formulate a digital marketing strategy based on the SEO guidelines. While some aspects of it are widely common like keywords, backlinks, etc. there are a few zones that aren’t very familiar to many.TF-IDF is one such zone. Although seasoned SEO experts make fair use of it, many who aren’t much associated with the whole search engine optimization scenario or are new to this, generally miss out on TF-IDF and needless to say, that creates unwanted gaps in their SEO efforts. So now, we will attempt to familiarize you with the whole concept of TF-IDF, so that you can utilize it in your digital marketing pursuits.
What is TF-IDF?
First, let’s abbreviate the term. Term Frequency-Inverse Document frequency is what TF-IDF stands for. Next up, we come down to its function. In narrow terms, it serves as a tool to measure certain aspects of your on-site content, particularly the text ones. However, in broad terms, it can be considered much more than a mere tool for text analysis. It is important to note that search engines such as Google uses this metric to measure the authority and quality of your website.
Term Frequency & Inverse Document Frequency
To describe the functionality of TF-IDF precisely, we must take TF and IDF separately. Just like we said earlier, it’s used to evaluate a piece of content or document. Term Frequency or simply TF measures the frequency of a term or word within a document. In simple words, it calculates the number of times a certain word or term is repeated in a piece of content. For Inverse Document Frequency (IDF), it evaluates the relevance of the said word in the whole document, i.e. how well a particular word fits the entire context of the document.
How TF-IDF Can Help You?
If we stitch them together, we equip ourselves with a fine method of evaluating our on-site content. Unlike other evaluating tactics that merely measure the quantity of a certain keyword in your content piece, TF-IDF does not work on the same lines. True, it also calculates the times a keyword repeats itself, but it does so differently. It measures how common a word is and based on that it produces its data. If a word is common or very relevant to the whole subject, then it would surely repeat itself more than a couple of times.This more or less, defines what TF-IDF does. Like all other aspects of search engine optimization, this too can be expressed in terms of digital marketing. It can be used by webmasters to evaluate and plan their web content and optimize it to gain search engine authority. To elaborate on this, TF-IDF is not some one-dimensional method of proofreading a piece of document. If used by smart hands, then it can produce valuable data on your target keywords. It can assist you in determining the correct path on securing a good ranking on a certain keyword or keywords.The application of TF-IDF extends to serving you the data regarding your competition and their ranking on a said keyword, plus suggesting your means and methods on how you can rank well in the search results.
How To Properly Utilize TF-IDF?
Now here it starts to get a bit tricky and to a certain extent, perplexing. Here, we use a bit of math and by math, we mean a certain formula that follows. Again, we will separate TF and IDF. This is due to the fact that they both are calculated on two different formulas.
The first we cover is TF (Term Frequency) formula:
Log (keyword count/word count)
The one above is the standard formula we use in calculating the Term Frequency. It’s not that complicated once you get the hang of it. To explain it with an example, if in your 1000 word article, your keyword appears 10 times, then the TF would be 10/1000. That was Term Frequency.
For IDF (Inverse Document Frequency) we use the formula:
Log (total documents/ documents with keywords)
That’s our standard procedure for solving our IDF problem. It appears pretty self-explanatory, but for getting a firm grip on the topic, let’s understand it with an example. If there are a 1000 documents and the ones containing the keywords are 30, then you calculate its IDF by 1000/30.After accomplishing our math homework by individually calculating the Term Frequency and Inverse Document Frequency, we multiply both the values and find the exact TF-IDF of our content. Although this may seem like a three-step process, the whole calculation many times becomes convoluted.
Tools To Calculate TF-IDF
As we were saying in the previous section, the whole calculation can sometimes take an intricate turn that can easily frustrate users. Well, not everyone fancies being a mathematician while planning his content according to the SEO best practices. Turns out you don’t have to do all the heavy lifting all by yourself. There are certain tools that are specifically designed for this purpose. So, you can embrace a hassle-free TF-IDF analysis with a fair bit of assistance from these tools.
