As a professional, it`s important to understand the use of informal contractions in English. Informal contractions are often used in spoken English to sound more natural and conversational. These contractions involve combining two words into one, and changing the original words` vowels or consonants.

Here are some common informal contractions in English:

1. “I`m” – this contraction is used to replace “I am.” For example, “I`m going to the store.”

2. “They`re” – this contraction is used to replace “they are.” For example, “They`re coming over later.”

3. “We`ve” – this contraction is used to replace “we have.” For example, “We`ve already eaten dinner.”

4. “Won`t” – this contraction is used to replace “will not.” For example, “I won`t be able to make it to the party.”

5. “Can`t” – this contraction is used to replace “cannot.” For example, “I can`t believe how fast time is passing.”

6. “It`s” – this contraction is used to replace “it is” or “it has.” For example, “It`s raining outside” or “It`s been a long day.”

7. “Didn`t” – this contraction is used to replace “did not.” For example, “I didn`t see that movie yet.”

8. “Shouldn`t” – this contraction is used to replace “should not.” For example, “You shouldn`t eat too much junk food.”

When writing for online platforms, it`s important to know that the use of informal contractions can help improve your website`s search engine optimization (SEO) by making it more conversational and easy to read. However, it`s important not to overuse these contractions, as it can make the writing appear unprofessional or sloppy.

In conclusion, understanding and properly using informal contractions in English can enhance the readability and SEO of your content. Just remember not to overuse them and aim for a balanced and professional tone in your writing.
