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.

Single keywords based SEO

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.

Ranking Keywords

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.
