Keywords for On-Page Optimization

[bracknelson]

Instead, use synonyms or latent semantic indexing (LSI) of your main keyword to get on-page SEO in the meta description, keeping search engines happy. For example, if your main keywords in the headline are “generate website traffic,” here are LSI keywords that you can use: get site visitors. drive free traffic.

Absolutely right, using synonyms of the main keyword is a safe way for not coming in the category of keyword stuffing.
