If you need support from Yola please contact us via firstname.lastname@example.org or make use of our live chat service! We are working on a new approach to community-based support and during this transition period we are not adding any new threads to this forum. Many thanks to everyone who has participated over the years and we look forward to unveiling a new peer-to-peer support system soon!
Once you have published your site again after making changes, search engines such as Google pick up on it quite soon. This can range from a day to a week, I guess depending on how often you update your content, how much traffic is coming to your site etc.
To speed up the process a bit, you can use Google Webmaster Tools and submit your sitemap to them. A tutorial to do this can be found here.
