To optimize the making of your Keywords, we advise you to follow these tips:
Write the Exact words. Those will be the ones the system will search.
Avoid using Meaningless words for the searchers.
Do not use articles such as the, a, an.
Do not use prepositions such as at, in, on, to, for, from, with.
Be careful with the use of adjectives. Try to avoid words such as good, nice, pretty, long-lasting, cheap, high-quality, expert, fabulous, better, great, big, etc. because they do not identify the product or service.
Do not waste your Words. You shouldn't write words that have no relation to the activity on the Ad.
Do not repeat Words. Once is enough for the system to recognize the Words.
The system recognizes both capital letters and lower-case letters, so if you write Florida it is not necessary to re-write it in lower-case letters (florida).
You do not need to write the city or the state.
If you consider it necessary, repeat the Word in plural or singular form.
Compound Words such as Chinese food, repair shop, bathing suit, etc. are accepted with no inconveniences.
