11 Free LSI Tools To Increase Your Ranking | LSI Keyword Generator

LSI (Latent semantic indexing) keywords are becoming very important to rank better in search engines, as an internet marketer people used to stuff focused keywords in their articles, overdoing this keyword stuffing gets a penalty from Google Penguin.
Repeating same keywords more than 2% in any article may get a penalty, it is better not to stuff those focused words.
To come out of this problem, Google has developed its search engine algorithm in a strong manner to understand more details about the article by looking at LSI keywords in the content.

What is Latent Semantic Indexing (LSI) keyword

As per the Wiki, LSI keyword definition is an indexing and retrieval method where it uses a mathematical formula called singular value decomposition to find out the relationship between the words and phrases from the collection of text.
In simple terms, LSI keywords meaning is the prominent feature of LSI is its strength to retrieve the conceptual content of the overall text by understanding the relationship between those terms which can appear in similar context.
So many of us think LSI keywords are synonyms to the seed keywords, but it is not true they are often synonyms but most of the times they are different keywords which have some relationship with the main keywords.
Here is the simple (latent semantic indexing) LSI Keywords example,
I am taking keyword “SEMrush Toolbar” because SEMrush doesn’t have any toolbar of its own, but their parent company has a toolbar with the name of SEOquake when I search this keyword in Google, let’s see what it displayed.
By looking at the above results, we can easily understand how Google search engine knows the relationship between SEMrush and SEOquake.

How LSI Keywords Will increase rankings

Most of the times people will not use exact keyword phrases when they are searching for particular information in Google search, LSI keywords will allow and help the search engines to understand what information he/she is searching for, as we seen in the above example I used entirely different keyword phrase for SEOquake but still Google displayed the results based on the relationship SEOquake has with SEMrush toolbar.
If we use the maximum number of LSI keywords in our content which are closely related with our main keyword then the number of keywords per article which are ranking in search engines will increase automatically because of this we get more traffic to our blog.

How To Implement LSI keywords In Our Article

Now we know the LSI keywords for our main keyword, but how to incorporate these keywords in our article is the most confusing process.
Before writing the article make a blueprint with headlines, and subheadings try to find out whether these keywords will able incorporate in subheadings of the content.
If you find those keywords will not disturb the core concept of your content then use these keywords in H3, H4 tags, and add these keywords in alt tags of the images except the first image because in first image we use our main focused keyword as alt tag text.
If they are not suitable to your content then don’t try to include those keywords in your content forcibly which disturbs the core concept of your content.
