There are a few points to note when optimizing Amazon titles:

1. Number of characters: English input method should not exceed 200 (80) characters.

2. Do not use promotional terms such as Hot Sale, New Arrival, Promotion, Free Shipping, etc.

3. Do not be redundant, do not repeat or overlap, and do not make spelling mistakes.

4. Capitalize the first letter (except for meaningless words such as prepositional articles for, with, and, of, or, etc.), do not capitalize all letters, and use Arabic numerals for numbers, such as "5" instead of "Five".

5. Use fewer or no punctuation marks, do not use special symbols (such as: $, ,!), and use spaces instead if necessary.

6. The measurement units must be spelled out in full (such as: Ounce, Inch, Gram, etc.).

7. The title cannot be changed at will.
