The number of keywords to target for local SEO marketing can vary depending on several factors. These factors include the size of your business, the number of locations, the competition in your industry, and your marketing budget.
In general, it's best to focus on a select few high-value keywords for each location that you serve. These keywords should be relevant to your business, products or services, and target audience. It's important to conduct thorough keyword research to identify the most relevant and valuable keywords for your business.
While it may be tempting to target as many keywords as possible, it's important to prioritize quality over quantity. Focusing on a few high-value keywords will help you to create targeted, quality content that will drive more conversions.
