Tips for writing an effective ad

1. Describe your product or service clearly.

2. Do not be too wordy, 20-30 words or less is a good length.

3. Be sure to include contact info.

4. Post only clear photos.

5. Follow copyright law. Do not use photos or text from manufacturer's website.

6. Stay to category. For example, do not advertise a car and a pet in the same ad.

7. Stay positive. Do not criticize another's product. Post the advantages of your item instead.
