As a webmaster who wants to promote his or her website using all possible SEO tools, you might have to hire a content writing service for generating SEO content for your site. However, this is not such an easy task, because sifting the wheat from the chaff is more complex than you might think. Given below is a list of the basic attributes that any good content writing service should have, so make sure that the one you hires fulfill this list of criteria.

· Should Be Able To Provide Examples Of Previous Writing. Almost all good content writing services will be able to provide samples of work that they have done before. This should be the first step involved in hiring a content writer so that you are not unpleasantly surprised by poor quality content later on.

· Should Have A Broad Range Of Experience. Even on the internet, the content that needs to be generated for different sites differs greatly in writing style, key word density, length and structure. Therefore, choosing a content writing service that has worked with a variety of businesses instead of choosing one that has lesser experience might mean that you will be able to get the best possible content for the market you are competing in. If you are going for niche content providers, make sure that they are operating in your niche. Otherwise, go for a service that has provided content for all kinds of sites.

· Should Have SEO Content Writing Expertise. Writing for the web is drastically different from writing for the normal print media. Even the best writers might not be able to produce high quality web content if they are not aware of the rules that apply to SEO content writing. So when you check a firm's previous samples, pay attention to the way in which keywords are used, in what quantity they are used and the way in which links are provided. Stay away from firms that provide web content full of fluff, flowery language and stuffed keywords.

· Should Be Able To Provide Test Samples. In the absence of references and testimonials, the content writing service that you are considering should be able to provide you with test samples of their writing. Ask the content writers to write some pieces based on guidelines you provide to check if their quality of work is well suited to your website or not.

· Should Be Able To Provide References And Testimonials. Most reputed content writing services will be able to offer testimonials or references from previous clients. However, there might be good freelance writers who might not be able to do the same because of the volatility of web businesses. Make sure that you get them to write test samples for you in case they are unable to provide references.
