There is much speculation about how long it takes Google to re-rank a site after quality issues have been resolved.
Some believe that it could be approximately 15 days, while others think you have to wait until the next quality update.
What is the real length of time you should expect it to take for quality improvements to be accounted for in Google’s algorithm?
In a Google Hangout with John Mueller, a webmaster was talking about this very issue. They were concerned about how they were still fluctuating in the search results, despite having made significant improvements to their website.
The webmaster then asked John if he could tell them how long it would take to re-crawl.
What Does Repairing Quality Issues Mean For You?
It’s really quite simple: if you’ve made changes to your site, don’t expect to see results overnight. Even though it can be maddening to wait(especially when your client wants fast results), you don’t have to be concerned if you don’t see rapid improvement in ranking.
Based on John Mueller’s information, if you’re making substantial quality changes to your site — more than just a few pages, for example — expect it to take 60-90 days for Google to recrawl the site.
This is why it is important to set client expectations early, and ensure that your client doesn’t have their sights set on an unrealistic date.
