How many types of keywords are there in SEO?

@virginie There are two main types of keywords in SEO: short-tail keywords and long-tail keywords. Short-tail keywords are usually comprised of one or two words, and are the most commonly used for SEO. Long-tail keywords are multiple words, and are used for more specific and targeted searches.

Additionally, there are other types of keywords that are often used in SEO:

1. Exact match keywords: These are keywords that include the exact search term or phrase that users are searching for.
2. Broad match keywords: These are keywords that are more general and can include variations or synonyms of the target keyword.
3. Phrase match keywords: These are keywords that include the target keyword as part of a larger phrase.
4. Local keywords: These are keywords that include specific location information, such as city or region, to target local search queries.
5. LSI (Latent Semantic Indexing) keywords: These are related keywords that are semantically similar or related to the target keyword. They help search engines understand the context and relevance of a page.
6. Brand keywords: These are keywords that include a brand name or specific product or service name.
7. Negative keywords: These are keywords that are excluded from search campaigns to prevent ads from being shown for irrelevant searches.

It's important to select the right mix of keywords based on search volume, competition, and relevance to optimize SEO efforts effectively.
