DOES A COMMA CHANGE A KEYWORD FOR SEARCH ENGINE OPTIMIZATION?

SEO: GOOGLE READS KEYWORDS
You're not the only one who wonders whether adding a comma alters the meaning of a keyword. In actuality, there are both many people who believe it does and others who think it doesn't.
In reality, when ranking pages for keywords like "keyword," Google considers a comma-separated phrase to be one word. This is because they read search terms in their index as single words rather than as separate phrases with commas or periods between them when they scan for them.

SEO: GOOGLE UNDERSTANDS KEYWORDS
The words you want to rank for in search engines are known as "keywords." In order to find your website or content, people also use these words in search engines.
Your chosen keywords will aid you in achieving your SEO objectives, but bear the following in mind:
Avoid selecting too many keywords at once; you don't want to overwhelm Google with them. To find out which keywords have a high search volume and how frequently they appear in searches, use a tool like Wordtracker or Long Tail Pro. This will help you figure out if a keyword gets a good amount of traffic and has a chance to rank well.
Use caution when substituting general statements like "how do I" for solutions. Despite the fact that these are distinct queries, Google treats them as a single phrase rather than potentially breaking up the answer into several results by including more specific details about the searcher's intent before they click on a particular result.

SEO: GOOGLE TREATS A COMMA-SEPARATED WORD THE SAME
A comma-separated word is treated exactly like a keyword by the Google algorithm. Since both contribute to your SEO score and are essentially the same thing, it's critical to understand how they differ from one another.
What are keywords?
When looking for a particular product or service online, consumers use keywords. If each keyword is relevant to what you're selling and includes variations on those terms, you can use them as part of your long-tail keyword strategy.
For example, Targeting a keyword like "Are RSS Feeds Bad For SEO?" Or something even simpler like "Best Candy."

YES & NO COMMA-SEPARATED KEYWORDS
Google will treat a list of keywords that are separated by commas exactly like a single word. Google will find and index that section of your website separately from other sections if you use commas to separate each keyword in your content. This is because it knows that these words are different things that need to be handled differently.
If your keywords aren't separated by commas, Google won't understand what they mean until after they have crawled all the pages on your website, and even then, only if the words are physically close to one another.
The main lesson here is to use commas to separate keywords. Check to see if your CMS is automatically inserting them between each word.

THEY DON'T CHANGE ANYTHING WHEN IT COMES TO SEO
It has been said that adding a comma to a keyword makes it sound more natural and less spammy. And if you employ them properly, it's true.
The main distinction is that commas will be treated as individual words rather than as a long string of letters when you use them in your content.
Therefore, there wouldn't be a comma between "husband" and "watch" if I said to you, "I want to buy my husband an expensive watch today because he deserves it after all his hard work."
A comma separating an ad from its keyword is more important than its absence. Google understands the difference between sentences and phrases, so you shouldn’t worry about using a comma in your ads at all.
