What is the top goal of a digital marketing campaign? The most common answer in this case is probably attracting as much traffic as possible. But how do you attract lots of traffic for a digital marketing campaign? Years ago, everyone knew SEO keywords were an extremely important factor, but recently Latent Semantic Indexing (LSI) has been drawing strong attention from many people. Let's explore with Markdao how LSI keywords influence your website's ranking.

What are LSI keywords? When did they appear in digital marketing?

LSI (Latent Semantic Indexing) refers to terms related to a concept that search engines use mathematical techniques to analyze — how keywords are grouped together to understand the content on a web page more deeply and completely. LSI has a history dating back to the mid-1980s, but only recently has the concept caught the attention of the digital marketing world, especially in SEO, since Google began using LSI for ranking websites on SERPs.

LSI keywords are, simply put, words that are semantically related to your main keyword. They are the words commonly found alongside your keyword in particular contexts. Let's see how LSI keywords work in the example below.

How do LSI keywords work, and how do they affect digital marketing?

Suppose your main SEO keyword is "Cars" — Google can understand this word in as many as 5 different senses:

• Cars — automobiles, a type of vehicle

• Cars — the name of a Disney animated film

• CARS — the acronym for the Canadian Association for Rally Sports

• CARs — the Canadian Aviation Regulations

• (the) Cars — the name of an American band active in the 1970s

So how does Google know which meaning your keyword "Cars" corresponds to? This is where LSI keywords become extremely important. Google searches for and indexes the LSI keywords on your page to determine the exact meaning of your SEO keyword:

• If Google finds the words "engine," "used," "drive," "buy," "sell," "price," it understands your page's content relates to the first meaning of "Cars" — that is, automobiles

• In another case, if Google finds keywords like "film," "director," "screenplay," "animated," "Walt Disney," it understands your page's content relates to the second meaning of "Cars" — that is, the Cars movie

• And so on for the other meanings

Why are LSI keywords important in digital marketing?

To answer this question, it will probably be more useful for your digital marketing campaign — and easier — if we look for the answer to the question: "Why did Google decide to use LSI keywords for ranking websites?" Rewinding to the early days, when SEO was a nascent industry, all Google relied on to rank websites was the keyword density in the articles on the site. By now we all know this indexing approach was inaccurate, because keywords could be stuffed shamelessly into articles under this method. That is exactly why Google decided to use LSI keywords as a ranking factor.

This way, Google can easily determine which of several similar websites has the higher-quality content. For example, two websites both selling "cars": if your page contains a variety of related words like "Toyota Fortuner," "Toyota Innova," "discount," "listed price," "maintenance," "installment," and so on, Google will score your page's quality higher than pages consisting only of the word "car" repeated many times.

How can you improve digital marketing with LSI keywords?

Have you worked hard and spent great effort finding the most promising keywords, yet the results aren't as expected? Have you produced technically rich articles with SEO keywords present throughout, yet your website traffic still isn't growing? Have you noticed your competitors using the same keywords as you and worried they might do better? Are you facing these problems? If so, try changing your strategy with LSI keywords. Below are 3 ways you can apply to improve your digital marketing campaign with LSI keywords.

Focus on the overall content rather than keyword density

After several recent system upgrades applying countless new algorithms, Google now places far more weight on a website's overall content — especially the context in which your keyword appears — than on keyword density. LSI keywords provide extra appropriate and valuable context for your keyword in particular and for your article as a whole. This means your page will rank higher for your main keyword because Google understands your page's context better — which in turn means your digital marketing campaign will have more chances of success by attracting more traffic.

Avoid Google penalties for keyword spamming

When you don't use LSI keywords, your only option is to cram as many keywords as possible into the article. This approach is obviously unsafe, because Google can penalize your website at any moment it feels you are spamming too much. With LSI keywords, you can both insert your main keyword and enrich the article's content.

Find keyword variants to use in digital marketing

LSI keywords are closely related to your main SEO keyword — in some cases they are called "keyword variants." Doing website digital marketing with LSI keywords means your page will appear in search results for your main keyword as well as for those keyword variants.

How do you find the right group of LSI keywords for your digital marketing campaign?

The best place to find LSI keywords for your digital marketing campaign is none other than where they work — Google. This way, you'll know exactly how the LSI keywords Google indexes correspond to your main keyword. You can easily investigate LSI keywords by typing your main keyword into Google's search box and looking for related words in the snippets on the SERPs.

Google Auto Suggest is also a useful tool for finding LSI keywords. This feature appears as soon as you start typing a search on Google, offering many search options for your main keyword. In addition, Google's "Searches Related To" section, usually at the bottom of the SERPs, is also an ideal place to find LSI keyword ideas.
