Posting every other day or skipping days rather than regularly posting on your website will not be going to attract traffic to your website. So, you should always have enough content in your hand that you can post regularly. One of the major benefits that regular posting will give you is that you will have regular traffic on your website which ultimately going to increase your organic traffic. Another thing is that your talent or skill will sharpen with regular writing & posting content. If you have a busy schedule or running a business at the same time, then you should hire writers to assist you.
All we found useful with this app was a link to download the Alexa toolbar, but that doesn't justify the steep asking price for this ineffective tool. There's a note that the registered program offers additional benefits, but doesn't elaborate. Frankly, this application seems designed to lure users to directing traffic to the unfamiliar site. We can't recommend it to any user for any reason.
To do this, I often align the launch of my content with a couple of guest posts on relevant websites to drive a load of relevant traffic to it, as well as some relevant links. This has a knock-on effect toward the organic amplification of the content and means that you at least have something to show for the content (in terms of ROI) if it doesn't do as well as you expect organically.
