Did some kw research and found a nice niche that has low competition. The .com emd however when you search g00g, 2 of the top 10 results are niche sites for the same item but they're domains are the plural. For example, i found smallspaceheater dot com is available but a search result shows smallspaceheaterS dot net and dot org are in the top 10. Both have horrible seo work and are very new sites. The rest of the results are ebay, amazon etc pages selling the item. Is it worth giving this a shot considering I'd hope to monetize with amazon and adsense?
