All You Need to Know About LSI Keywords

LSI keywords (Latent Semantic Indexing) are used by search engines such as Google to better understand what your web page content is about.

They are conceptually related. And with the search engines getting smarter by the day, they can help your content rank… even when your primary keyword hasn’t been used.

What Makes LSI Keywords Important?

In the past, the search engines relied completely on the keywords used in content to understand what the topic was about.

That used to make ranking content much easier. All you needed to do was repeat your primary keywords again and again.

The search engines saw the repeated keywords and came to the conclusion that the content must be based on them.

As an example, if you repeatedly used the keyword ‘organic gardening’ in your content, Google would look at it and decide that the content is about organic gardening… obviously!

This is where content keyword density was born. In order for Google to understand your page content, your primary keyword needed to be used as a certain percentage of your word count.

Jump forward in time to today, and Google works to understand the overall topic of your page. Yep! Google is getting smarter… much to the annoyance of old-school marketers.

But how do LSI keywords help Google dig deeper to understand your content?

Here’s an example:

Imagine you publish an article ‘growing organic vegetables.’

The first thing that Google does is check your image alt text, subheaders, content and your title tag.

Then it moves on to scanning your page content for latent semantic indexing keywords.

For ‘growing organic vegetables’, it will be searching for related keywords such as ‘chemical-free’ ‘green’ ‘clean’ ‘non-GMO’ and ‘organically grown.’

Once Google has finished its scan and has found LSI keywords, it is able to ascertain that the topic is indeed about ‘growing organic vegetables’

While they look like synonyms of common words, LSI keywords are actually terms and phrases closely related to your primary keyword.

But how exactly do you find the best LSI keywords for free?

How to Find LSI Keywords

Google Autocomplete

Google might love making a marketer’s life a misery by constantly changing algorithms. However, it does come with its own set of benefits too.

The quickest and easiest way to find LSI keywords is to use Google autocomplete.

You will notice that every time you perform a Google search, it throws up recommended Search terms.

As an example, when you type in ‘growing organic’ Google autocomplete comes up with growing organic vegetables, growing organic tomatoes, growing organic strawberries, growing organic apples and growing organic corn.

When looking at Google autocomplete, the words that are bold are the LSI keywords. So, you know that you can add these into your content to help Google join the dots.

While there are many other LSI keyword tools available on the internet. Google serves up the most popular and relevant LSI keywords from the get-go.

The second way to find LSI keywords and terms can also be found on the search results page of Google.

This differs slightly to Google autocomplete as instead of instantly giving you suggestions while you perform a search, it instead chose you related terms.

To find the ‘searches related to’ section on the Google search page, simply scroll down to the bottom. Again, if you want to look for the terms that are in bold.

You should also make sure that the bold LSI keywords are relevant to your content. If they are, then find a way to weave them into your content.

Google Meta Descriptions

The final way that you can use Google to find LSI keywords is to look at the snippets shown for each page ranking in the search engines

Whenever you perform a Google search, these snippets will contain words in bold that are related to the main keyword you search for.

However, it goes a little bit further than this and also bodes any related terms or phrases.

You can take it as read that these are LSI keywords you can use throughout your content to improve your ranking.

Keywords Everywhere

Keywords everywhere is a handy Google Chrome add-on that throws up a whole wealth of keywords related information for free!

Not only does it give you the search volume, CPC, keyword difficulty, etc. whenever you perform a search, you can also use it for on page analysis.

Simply install the Google Chrome add-on, head to your competitors page and analyse their content.

If your content is covering a similar topic, this not only helps you find LSI keywords but also helps you discover other rank-able keywords you may have not thought about.

Where to Use LSI Keywords?

Unlike standard keywords, there are no hard-and-fast rules about where you should place your LSI keywords.

Of course, it is seen as good practice to always include a keyword in your title tag, as part of your H2 sub-header, and in the content itself.

So it makes complete sense to use your LSI keywords in these too. Why? Because these are the things that Google first looks at before moving on to your content.

The sooner you can help Google join the dots, the more likely it is to understand your content and show it to the right people.

And ultimately, that is what you want. If the wrong people are showing your content, you can pretty much guarantee they are going to hit that back button at lightning speed!

And that tells Google that your content didn’t satisfy their needs.

In turn, this can drastically reduce your chances of getting on the first page of Google.

Final Word on LSI Keywords

If you are serious about your SEO techniques, then you should be using LSI keywords in everything that you produce.

While it might take a little more time to include your LSI keywords. In the long-term, it will save you time as you don’t have to re-optimise  your content for better ranking keywords.

Whether it’s a person or AI, being able to understand something equates to a greater chance of success. So optimising your content to help both readers and search engines gain a deeper understanding of your content context can provide you with truly amazing search engine rewards.
