I want to edit some articles of mine at articlesbase. Does it mean the articles'll be re-indexed with google the unique stuff again? I put my site url into my pieces without anchor texts. Simply, i'd like to fix it. Or better not touch the published articles?
Yes, the updates will take effect when Google spiders the page. Most article directories have sitemaps that tell Google when a page is made or updated.
It will not effect unless you change your url if you change your url then redirect it through htaccess file
The only thing that will happen is the article directory will have to approve your article again... the URL does not change.
Editing an article doesn't mean that URL of the article will be changed. Right?. So you are just gona to change the content. Search engine will soon cache the new content and there won't be any problem. URL is already in the index you are just updating the content.
