Writing content for websites can help in providing you a regular stream of income, however, as I have mentioned, it is relevant to you and a few other things:
Most editors and employers targeting an American audience prefer material written by someone of such qualification. Nonetheless, this is not always true in writing content for websites, if your command of English is good enough that it allows you to express your thoughts with ease and minimal grammatical errors and suppose you have trained yourself well in the technicalities involved in Search Engine Optimization, you may as well be qualified. However, the competition is active, and differently, you have a portfolio to back up your claims and samples of your previous work then be prepared to be turned down a few times.
My advice is to take on jobs that do not require certifications from American boards and those that may pay a little lower, but you can succeed with. Here is a good way to show off your skills if your first language is not American English, there is no amount of technicality that can replace a native language, be ready to face it.
Clients will always look for a piece you have written to review your job. Do not expect that your claim as a writer is enough to be considered. While a well-written cover letter can help you recognized, at some point clients will look for your published work, be it your personal blog or collection from an article source website. If you have not yet, begin now.
Your writing style will allow clients to have a feel whether you are appropriate for their target audience. We all write in a certain way, in fact, every writer weaves thoughts into words so similarly unique as that of a fingerprint. You may pattern your writing style to successful writers in a certain market you wish to penetrate but ensure you do not lose your identity for the in the long run your clients will be looking for that uniqueness.
Where to find gigs
There are plenty of job boards out there for writers, almost all of them claiming to be better than the other. Another kind of freelance job websites posts a list of various topics that you can write about and then it will be returned. Pricing also varies upon your skills and your location, if you are not a native English speaker do not expect the figures offered to be the same. However, it is not the end of the world, try classified ads out there that list postings directly from an employer and send out a sound letter with samples of your work. It may prove even better since you are directly employed other than going through a third party website which takes a little amount from their members' earnings.
Writing contents for websites should be your road to greater growth. It should allow you to find long-term projects to ensure a steady stream of income from writing. Just keep on applying for jobs and writing posts in your blog. The more material you have to present to any client the greater, you will be considered.
