A few clarifications:
1. Republish feature with automated system would not work out, as then even old articles that are no longer relevant or not of good quality would be republished needlessly.
2. No, do not republish all articles. Use the check traffic feature (the author can see this on log-in). If the article has generated traffic, then it makes sense to republish it.
3. When you edit an article to update information or correct some wrong details, then you cannot republish it right away. It will first go into new submission mode for editorial review. Then, if approved again, you can republish it.
4. In the case of admissions article, if it has generated good traffic, you can keep it as it is, with change in academic year in the title, summary and text and update it with the new schedule of dates of opening and closing of admission. Do not blindly just update only this info though - check official site to know if the application procedure has changed too. For example, the college may have decided not to have an entrance test for meritorious candidates or may have put in a rule that the student has to appear for a written test at the college campus and not appear for an online test at a nearby centre in his/her city as is the norm. Make sure therefore that your article is up to date in every respect as per the current scenario. Ideally, though, it would be a good idea to submit a totally fresh admissions article as the old one will have a short shelf life &, though it generated traffic at the time of the previous academic year's admission season, it will subsequently not be of any use to students. Remember: admissions to reputed schools and colleges will always get traffic each year.
5. You can see the fresh date after republishing, which is the indicator that it got re-published. You will get the usual alert that it has been approved.
6. Republishing evergreen articles, meaning those which will generate traffic for the long term, is definitely beneficial for you. Let's say you have written an article on the rituals of a particular festival. What you could do is time the republishing about 1-2 months before the festival comes around again.
7. If the article was posted in the initial years of ISC and you update and improve upon it, you just may get more points and cash credits than what you got earlier. As the site has developed and generated good revenue, authors of good articles would be rewarded with better cash credits than when the site was in its budding stage and there was a tight rein on the budget. Remember: in many old articles you will see the asterix (*) symbol or words put in bold in many sentences, no proper summary, etc. So, if you are updating, you must use the current guidelines, namely not using too many bold tags, putting headings with h2 or h3 tags, using tags & not symbols for points, avoiding salutations at the beginning and end, putting a proper summary, etc.
Important note: In the message to editor's box, please briefly mention that you have updated the info in the article or just republished it, as the case may be.
