Search Engine Optimization (SEO) is both a science and an art to ensure optimal organic search engine results.
There are a lot of different ways to say the same thing. Anyone who has performed keyword research knows that people search for a lot of the same things using very different phrases and terminology. For example, if you're looking to build your online business, you could search for: online marketing, website marketing, Internet marketing, website promotion, search engine optimization, search engine marketing, SEO, and a dozen other variations.
Your website may have different pages on your site that can be focused on different aspects of your production services that cover each topic as separate areas. In other cases, similar phrases can be used interchangeably throughout the site.
The problem comes when each of these similarly defined terms is extremely competitive, and using them interchangeably won't allow you a strong enough SEO focus to achieve rankings for any of them. You need pages that focus on one or a few phrases at a time if you want them to be successful.
Optimize Similar Keywords on Existing Site Pages
Ideally, you want to target keywords that are already a natural fit for any given page. But, when several keyword phrases essentially mean the same thing, there is no clear distinction to be able to say definitively which keywords fit where. For example, "keyword research" is pretty clear while "keyword optimization" can mean the same thing as SEO and several other phrases.
1. Target a Single Phrase. One easy solution is to find a content page relevant for any group of similar meaning phrases, choose the highest volume phrase and target that phrase. Since each phrase basically means the same thing to the typical searcher, changing all instances of various phrases to the single phrase you're targeting can be done without changing the meaning of the page in any way.
