I blocked Google from crawling my domain using a robots.txt rule
User-Agent: * Disallow: /
by mistake. Just recently I noticed, two months later, and I removed the robots.txt file. The website was previously well ranked for certain queries. Now it is obviously not, with most webpages having disappeared.
Will I take a permanent hit on my rankings because of this? How much time should I expect it will take to recover it? Is there anything I can do to speed up the process?
