SEO: Semantic Optimization

Semantic Optimization is a crucial part of SEO

 The semantic optimization of a website is not only about inserting appropriate keywords and keyword phrases within a text a certain amount of times, but also inserting words which are related to the main keyword.

The Importance of Semantic Optimization

In the early days of search engine optimization, it was sufficient to just use one central keyword a certain number of times within a text to satisfy the demands of search engines. Although a certain density of keywords is still an important element of modern search optimization, it is no longer the sole decisive factor for success. For example, if your website is about sports cars, it is no longer sufficient to fill the text content with the word “Ferrari”. This is because Google now uses a technique called Latent Semantic Indexing (LSI), which requires websites to use a semantic tag cloud to provide visitors with more varied and relevant information. Still using “Ferrari” as an example, related terms may include “race car”, “Michael Schumacher”, “Italian car”, “Formula One”, “Enzo”, “Modena”, “red”, “Bella Macchina” etc.

Keyword Density

The ideal density for the primary keyword and its synonyms within each individual URL is 6%. So, for a text of 600 words, his would equate to ten times. Furthermore, secondary keywords which are semantically related (sub-keywords) can be used throughout the text with a much lower frequency. This will provide each piece of text content to appear on a website with greater depth and information.

Another option, which is more complex but still widely used, is creating an website dedicated to the principle of a tag cloud. This entails, for instance, optimizing the homepage with the primary keyword and some URLs with a choice of secondary, related keywords. This method requires a specialised method of internal linking in order to be a success in regards to SEO. This linking method requires each subpage to contain the primary keyword at least once in the so-called “anchor text”, which will link back to the homepage. Additionally, these subpages should be cross-linked with the respective secondary keywords also serving as anchor text. This strategy enhances the inner structure of the website, which can then be smoothly indexed (“crawled”) by search engines.
