Google's temporary blocking crawler, will it prevent future indexing?

Question

Sometimes I need to add a few updates to my site. To keep it clean, I display a service page. The first time I did this, it became the main indexed page on google. So I added the <META NAME="ROBOTS" CONTENT="NOINDEX, NOFOLLOW"> meta tag to prevent this. My question is: if google gets to this temporary maintenance page, it will not index it, but does this mean that it will never index this page again? or will they index the page again when there is new content?

I would really appreciate if someone could clear this for me

Answer 1

Google crawler will reindex your site after removing the meta tag (it constantly updates its indexes).

If you’re really paranoid, I’d recommend checking out Google’s webmaster tools so that you can directly control the indexing behavior of your site: http://www.google.com/webmasters/

Answer 2

Google has a guide to planning maintenance / downtime: " How to deal with planned site downtime. " in short, you should return the result code 503 HTTP on those pages (pages) that are under maintenance or do not work. here is a sample php code to use on top of these pages:

 header('HTTP/1.1 503 Service Temporarily Unavailable'); 

if you know the exact / approximate time / date of completion of service / downtime, you can use an optional Retry-After header similar to this (along with the above HTTP result code 503):

 //when the exact completion time is known. header('Retry-After: Sat, 8 Oct 2011 18:27:00 GMT'); 

or

 //when the length of the downtime in seconds is known. header('Retry-After: 86400');
