Having a different description meta tag for each page helps both users and Google, especially in searches where users may bring up multiple pages on your domain (for example, searches using the site: operator). If your site has thousands or even millions of pages, hand-crafting description meta tags probably isn't feasible. In this case, you could automatically generate description meta tags based on each page's content.
For some reason I had to delete some pages, these pages are using the HTML suffix, so I blocked them in robots.txt use Disallow: /*.html, but it’s been almost a year, I found that google robot often capture these pages, How can I quickly let Google completely remove these pages? And I have removed these URL from google webmaster tool by google index-> remove URLs, but Google still capture these pages.
Consider outsourcing article writing. If you hate the thought of generating content yourself, or your team is not writing-savvy, consider outsourcing this end of the task. Depending on the length, content, specialization and quality required, prices can start as low as US$5 per article. However, don't neglect attempting to write your own work - who better than you knows your own business, hobby or club and can express precisely what needs to be said?
Headlines are one of the most important parts of your content. Without a compelling headline, even the most comprehensive blog post will go unread. Master the art of headline writing. For example, the writers at BuzzFeed and Upworthy often write upward of twenty different headlines before finally settling on the one that will drive the most traffic, so think carefully about your headline before you hit “publish.”
