The choice of keywords will directly affect the effect of advertising. The same product will have different conversion rates when using different keywords. Sellers must have a deep understanding of the product, understand which keywords are the keywords of the product, and how to choose keywords suitable for the product. Therefore, before placing an advertisement, sellers must have a detailed understanding of the attributes and characteristics of the products they sell, and on this basis, choose accurate keywords for the products.

When choosing keywords, precise keywords and long-tail keywords are preferred, and broad keywords (big words) are carefully selected. For novice sellers and sellers with a small advertising budget, it is particularly important to pay attention to the use of long-tail keywords, because buyers who use long-tail keywords to search for products generally have a strong desire to buy, so the conversion rate of such words is relatively high, and the competitiveness of long-tail keywords is relatively low, so the cost of advertising is also lower. If the seller is not sure about the choice of keywords, he can use some keyword analysis tools to help him sort and screen.

At the beginning of advertising, the keywords may not be the most appropriate due to insufficient understanding of the product, but after a period of advertising (usually 4 to 6 weeks), the seller can adjust the keywords according to the advertising data analysis report in the backend of the seller center. Keywords with high exposure, high clicks and high conversions should be given priority; keywords with high exposure, low clicks and low conversions can be deleted as appropriate, and new words can be added.
