If your site has been adversely affected by this update,
Chinese Overseas Europe Number Data Google has a list of questions that you can ask yourself about your content and pages:
Does the content provide original information, reporting, research or analysis?
Does the content provide a substantial, complete or comprehensive description of the topic?
Does the content provide insightful analysis or interesting information that is beyond obvious?
If the content draws on other sources, does it avoid simply copying or rewriting those sources and instead provide substantial additional value and originality?
Does the headline and/or page title provide a descriptive, helpful summary of the content?
Does the headline and/or page title avoid being exaggerating or shocking in nature?
Is this the sort of page you'd want to bookmark, share with a friend, or recommend?
Would you expect to see this content in or referenced by a printed magazine, encyclopedia or book?
What this comes down to is simple: website owners need to focus on creating valuable content for people, not just to rank in search results.
