In the context of SEO and digital marketing, a keyword is any search term that a user enters into a search engine. Keywords can be single words (like "plumber") or longer phrases (like "emergency plumber in Pontefract open on Sundays"). The longer, more specific phrases are often called long-tail keywords.
Keywords are the foundation of SEO. By understanding which keywords your potential customers are searching for, you can create content that matches those searches and increase your chances of appearing in the results.
Keyword research involves finding out what terms people are actually searching for, how many searches those terms get per month, and how competitive they are. Tools like Google Keyword Planner, Ahrefs, and Ubersuggest can help with this.
Once you've identified relevant keywords, they're woven naturally into your page titles, headings, body content, meta descriptions, and image alt text. The emphasis should always be on writing for humans first and search engines second.
