1 When you change the structure of your site
, you can let Google know by uploading a new XML sitemap. This enables the search engine spider to revisit your site and capture the new information.
2 When you’re signed up to Webmaster Tools, Google will alert
you to any issues with your website, such as hacking attacks, and give you the opportunity to resolve the problem before it affects your listings.
3 The very best way to ensure your website performs well in Google (and other search engines) is to make your site unique; your content should be your own, and not copy another website.
