The old days of keyword stuffing died a while ago. Google now uses complex algorithms such as “Latent Semantic Indexing”. This article gives a nice straightforward account, with the quote below getting to the essence of it.
My key take-away is that content curation is a way to build a rich set of articles containing a wide range of ‘semantic’ terms that will boost your content ranking. By highlighting some of the best writing on a topic, you are creating a broad range of ideas, phrases and words that revolve around your theme. I think Google picks up on this and starts to see your site as one with a lot of relevant content.
In the example given below from the article, as you curate content on ‘natural gas’, you are going to be quoting various excerpts from a range of articles. These quotes will use many terms and phrases as they discuss the natural gas industry. You’ll also be reacting with your own comments and opinions. The body of this content will naturally be very rich in the ways it discusses and uses synonyms and ‘semantically similar’ phrases. All without you having to count keywords or synonyms. It becomes a natural extension of good curation to build better SEO content.
The term “Semantic Indexing” is just another way of saying synonyms (shown in the infographic as a clue algorithms take into account to understand what searchers mean). Using a variety of synonyms related to your target keyword is extremely important to rank higher on search engines.
One of my clients here at Blue Corona, for example, is a natural gas company. As opposed to sprinkling in just “natural gas company” throughout the copy, semantically related terms include (but are not limited to) fossil fuels, natural gas prices, natural gas supplier, heating oil, propane, etc. It’s important to use these terms in your copy so that it sounds natural and creates a beneficial user experience, which is the key to higher search engine rankings.
Now, content curation is directly related to the LSI keywords. How so? The process of curating content from legitimate, trustworthy sources will naturally lend itself to incorporating LSI keywords within the copy you produce.
