Never compromise quality. Many are correct to say that focusing on quantity causes the deterioration of your quality and may decline your readership. Though it is not necessary that you will just stop writing your content.
Strategy here is to start strong with just a handful of high quality content. Make sure you have checked the content more than twice. If its a blog, post it on your facebook, if the reaction is high, then put it on your blog. Then, with this quality content you will build your desired volume through your readers. If your content is really that good, you will definitely have a great audience volume.
Let's say you already have the desired readership, all you need is to maintain everything. Be consistent with your content. Improve your style, make it evolve. This way your existing readers may even recommend you. Another technique are presenting your content as a series of articles. Make a starting lineup of 5 topics at the start, then develop them further by writing updates and sequels.
And lastly, make your release dates consistent. Make a schedule for new content release. Doesn't have to be 5 articles a week, make it 1 per week. You may have 5 ideas all at once but release only 1, then plot your other 4 on the calendar for release dates. This way you have time for proofreading, editing, and further research. If you use this approach, you can ensure that you will not run out of content to release. Why release 5 now then end up with a mental block and not be able to release for the next 4 weeks? 1 per week plotting will maintain your visibility, and will give your readers the impression that you are indeed active, giving them more opportunity to recommend you to other readers.
