8. Visit forums and blogs
Forums are not just for people, who want to complain, but lack time or guts to do it in real life. You can find a lot of very skilled experts about all possible topics and many of them will be happy to provide you an answer if you have a specific question regarding your article. Of course, to get the best answers, you have to sound like a consumer in trouble. A role, which should not be too hard to empathize with, huh?
Almost the same approach is useful at blogs too. You just have to find leaders in every specific industry. A Google search:
best blogs about 'your topic'
can serve as great starting point.
Don't forget the basic etiquette on forums, where are especially sensible to spam. Open a profile, fill it out, try to contribute, in general - be a member, not abuser. By the way, the same approach works fine in off line life as well. If you, for instance, work on article about digital cameras, you can call a service dealing with the specific model you are trying to promote. Try to reach the man (in most cases this is a testosterone packed area) who repairs broken products. You have to sound like a nice, worried and not too smart consumer. Ask, for instance, what kind of repairs can you expect, in, let's say, next two years, if you buy a specific model.
With a bit of luck you will get info manufacturers NEVER provide, official reviewers RARELY discover and is ALWAYS in high demand among buyers. Sounds like a winner?
9. Exploit dedicated sites
Every niche has at least few authority sites about the subject. Some are very rich with content and supported with major off line magazines, other run by devoted enthusiasts for many years, so you can easily familiarize with professional jargon and get used to the theme. Instead of listing hundreds of magazines which can serve as great resources for your on-line writing, I'll give you a pro tip on very specific problem every serious researcher sooner or later bumps into.
Many of the best sites require some kind of membership to give you full access to the articles. Several of them allow Google to index their archive or articles (what helps them ranking), but don't allow visitors to read indexed content without registration. Well, in some cases you may go around this obstacle by reading the cached version (if any) or translate the content directly from search results without prior opening. When the content is translated (in any of gibberish versions), just simply click on the 'read original' option and you'll have full article.
This trick will not work always and I am not sure if somebody can claim any kid of copyright infringements in case you read something you are not suppose to, so I officially declare I don't use this method. I just mentioned it to look more cool competent.
For instance, in the wedding niche, you will probably want to check:
My Dream Wedding Ideas
which all provide a lot of quality and unique info about weddings.
10. Visit your local library
More and more libraries offer more and more digitized content, so you can play a researcher without putting your slippers off. You can actually write without leaving your bed. But if you want to excel in your writings, some dirt on your soles will not hurt.
Libraries are still a great resource of very versatile knowledge which is in most cases written by much more qualified writers than the average contributors of different wikis or revenue sharing sites. The reason is simple. Even if you are dealing with vanity press, somebody had to believe in author enough to invest in paper, binding and other old fasioned materials which can still provide a lot of unique and quality info, just right for every niche writer.
I do that all the time. But enough about me ...
