There could be several reasons why another website appears at the top of the search engine listing when you type in "Jamaica Homes" on Google instead of jamaica-homes.com:

1. Search Engine Optimization (SEO): The other website may have invested more resources into optimizing its content for search engines. This includes using relevant keywords, creating high-quality content, and acquiring backlinks from reputable sources, all of which can improve its ranking in search results.

2. Domain Authority: The competing website may have a higher domain authority, which is a measure of how well a website is likely to rank in search engine results. Factors that contribute to domain authority include the website's age, popularity, and the number of backlinks it has.

3. Content Relevance: Google's algorithms prioritize websites that are deemed most relevant to the user's search query. If the competing website's content is perceived as more relevant to the search term "Jamaica Homes," it may rank higher in the search results.

4. Local Search Factors: Google takes into account various local search factors when displaying results for queries related to businesses or services in a specific location. The other website may have better localized content or more favorable reviews, contributing to its higher ranking in local search results.

5. Advertising: It's possible that the competing website is running paid advertisements through Google Ads, which can appear at the top of search results. These ads are displayed based on bid amounts and relevance to the user's search query.

Overall, a combination of factors such as SEO efforts, domain authority, content relevance, local search optimization, and advertising can influence which website appears at the top of the search engine listing for the query "Jamaica Homes" on Google.
