Where should I put the +1 button on my pages?

You know your page and your users best, so we recommend putting the button wherever you think it will be the most effective. Above the fold, near the title of the page, and close to sharing links is often a good location. It can also be effective to place the +1 button at both the end and the beginning of an article or story.

+1 is a public action, so you should add the button only to public, crawlable pages on your site. Once you add the button, Google may crawl or recrawl the page, and store the page title and other content, in response to a +1 button impression or click.
