What is LSI?
Latent semantic indexing (LSI) is a strategy used by search engines to analyze the related words (LSI Keywords) that people use for a given topic.
What are the LSI keywords?
LSI words are words or phrases related to the target topic that Google’s algorithm uses to understand the content on a webpage.
What is Google’s Algorithm? – Hummingbird and Semantic Search
In August of 2013, Google announced the Hummingbird Algorithm, also refers as a semantic algorithm. This algorithm enhances the ability of Google to deeply understand the synonyms context of the webpage. Basically, it is the concept of improving search results by focusing on user intent.
Why Do Google Use LSI Keywords?
To enhances its ability to better understand the synonyms context of a particular webpage. So, Google uses LSI to know searcher intent.
Example Of LSI Keywords:
I searched for hair straighter in Google. It gives me suggestions but these autocomplete suggestions are not LSI words. These are the queries that people searched for more.
LSI google suggestions for “hair straightener” topic are:
⇒ Wavy hair
⇨ Hair straightener brush
⇒ Fizzy hair
⇒ Flat irons
⇨ Damaged hair
⇒ Bouncing curls
⇨ Hair tools
What Is The Difference Between LSI Keywords and Long-Tail Keywords?
|LSI Keywords||Long-Tail Keywords|
|1. These keywords are not the target keyword in the content.||1. These keywords consist of more words with lower volume derived from a seed keyword.|
|2. LSI is keywords that must be in the blog to let the search engines know that your article is about the long-tail keyword that you are trying to focus on.||2. Long-tail keywords lead to better conversion rates which make them easier to rank for.|
|3. These keywords help in improving the article ranking||3. While writing content, you need to focus on a single long-tail keyword.|
|4. Example of LSI: If the seed keyword is Osteoarthritis, then LSI keywords are Joint, Pain, Lower back, Knees & Treatment.||4. Examples of long-tail keywords: If Seed keywords are Osteoarthritis, then LONG Tail Keywords are Best Osteoarthritis Doctor, osteoarthritis treatment in Ayurveda, etc.|
Why LSI Keywords Are Important In SEO?
In the old SEO keyword strategy, Search engines used to figure out the same topic-based keywords on the page.
If Google saw the keyword “Content Marketing” used in your content multiple times, it will consider that page is about content marketing”.
That’s why keyword density had importance in earlier SEO.
If you didn’t use it so many times, Google wouldn’t be able to understand your target topic.
But now Google has become much smarter than before. Today, Google’s goal is to figure out a page’s overall topic.
And, now Google focuses more on LSI keywords to understand content at a deeper level.
Example- let’s suppose you published a blog on the topic “social media.
But still, Google will analyze your page to see the term “Social media” in your title tag, content, image alt text, etc.
And it will also scan LSI keywords like “Facebook”, “twitter”, “Snapchat” and“ Pinterest”.
So when the search engine found LSI in your content, it will come to know that this page is about social media.”
How To Find LSI Keywords?
While searching for LSI terms, don’t even try to focus on synonyms. Just look for related terms and phrases.
1. Use Common Sense
