How To Use LSI Keywords in SEO


Despite keywords being the base of searchable web writing, too many sites neglect it. Therefore, in this article, we will discuss one SEO trick that is going to help you improve the searchability of your blog posts – Synonyms. Synonyms are particularly crucial in SEO.  Most webmasters have stated them as road signs for search engines.

What are Synonyms or LSI Words in SEO?

Synonyms are words that mean the same thing. ‘Large’, and ‘enormous’ are synonyms for huge.

Google has included Keyword Stems in searches for a long time. An excellent example of stemming is where you use the keyword “running”, and Google will provide results with run, runs, or running in their results.

Synonyms, on the other hand, are entirely different words that have no part of the original word within the search.

Here’s a good example: a person might “run” a company or “manage” a company, essentially, “run” and “manage” mean the same thing in this context, even though they are entirely different words.

Why use LSI words for SEO?

Search engines—especially Google—use synonyms and other related terms to figure out what your page is about. This is called latent semantic indexing. Once a search engine has a keyword in its sights, it searches the rest of your copy for context. For example, if your page’s title contains “orange,” you might be writing about fruit, or colors, or Dutch monarchs. But if search bots also find the terms “soccer,” “Netherlands” and “Jersey,” they’ll cleverly assume your page is selling shirts for fans of Holland’s national soccer team.

Using synonyms effectively can make a search engine’s job easier—which can increase your ranking.

    I usually use the quick search bar of google and optimize my post title for the synonymous keywords.

    Looks like I have to take English classes again or I shud put a thesaurus beside me while writing a post. 🙂

    I observed this a while back and this phenomenon has been sending traffic to my blogs for some similar keywords, aka Synonyms.

    Nice to point it out for the readers.

    Just do search again. I did it on and When i searched for “royalty free pictures” for both and no synonym for “photos” is highlighted.
    Also, i searched for “royalty free photos” but no “pictures” highlighted. So, i don’t think synonyms is needed untill it is giving high traffic. By the way ” “royalty free photos” has high traffic and High CPC as compared to “royalty free photos”
    If i wanted to target “royalty free pictures” then i will not bother about “royalty free “”photos””. Good example is which is ranking on 10 place now. I will use the words from google tool or other tools.

    Still i say very good post and new thing.

    Keyword stuffing and keyword density in the articles is very important part of the SEO.Synonyms can work really well in the articles but keep in mind that synonyms should only be used when require otherwise readers will not like your writing style and bounce rate of readers can increase.

    1. TechPaparazzi

      Yes Asad too many synonyms can lead to a huge damage on both SEO factor and Reading too…..

    This is really great for writing articles because it can take an article that sort of sounds heavy on keywords and turn it into something that has better readability.

    So now you gain that people can read it more easily and search engines love it 🙂
