My blog url got de-indexed

[frank]

Wait atleast two weeks. It happens sometime that when we publish any post we submit it in the webmasters tools and also outreach it through social media channels. If the publishing blog is already popular then the search engines show the post in the SERP's but later after some time they evaluates the page and re-rank it. This periods between ranking first and re-rankling may take some time and its totally fine that your post does not appear in the SERP's within this time being.
