Where can I get information to increase my credit?

I recently applied for a credit card to help increase my credit but it went down by a lot? I am wondering what happened.

Credit card company.

What happened is that you applied. Applying always makes your credit go down. You cannot increase your credit by applying. To increase your credit, you must stop applying. It will take one year of not applying to increase your credit to what it would have been if you had not applied.

When you apply for new credit, your credit scores will take a hit, but don’t worry, they will soon recover.
