I am usually working on a dozen to two dozen articles at the same time. This is because I am easily diverted from one project to another. But have found that I do the best work when I go with whatever energy is hot in my mind. I need project management software for the scatterbrain.
Articles can hang for months without being touched because I hit something difficult, need props for photos, need to travel for photos, graphics are being made, license/permissions, these things eventually get done and these delays almost always result in a better product.
So, I have a master spreadsheet in a google document that tracks each step of the content preparation job. Each row in the spreadsheet is a page of content, and the columns are the various jobs that must be done for each of them. I can tell at a glance what is missing or needed for any article.
Column headings include: research, mind map, writing, photography, graphics, posting to html, online review, spell check, editing, tag checking, publish to the homepage, announce to subscribers, incorporate into category pages, locate places to link internally, monitor analytics (change thumbnails or graphics of not performing).
Some of those jobs are done by me, some are done by an employee who is here daily, some is done by a part time employee who works irregularly, some are outsourced. The spreadsheet puts all of this in order and makes sure that important jobs are not skipped.
I also create a google document for each page of content and share with an employee who does photos, graphics and creates the html pages. That is where I compose <title><description> and author the article. The employee prepares the images and adds them to this document. I write captions for each image. When everything is finished a pdf of this page goes to an offsite editor, when it comes back I do final adjustments, the employees post the article to the website, a tag checker proofs everything, then we look at the spreadsheet to be sure that all jobs to promote the content have been done.</p></title>
