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.
Guest blogging is a two-way street. In addition to posting content to other blogs, invite people in your niche to blog on your own site. They’re likely to share and link to their guest article, which could bring new readers to your site. Just be sure that you only post high-quality, original content without spammy links, because Google is cracking way down on low-quality guest blogging.
Great content. Although I disagree with ‘the best times to post’ section. It is important to understand your audience. For example, if your brand/business is in high school, there will be low engagement until 2-5 when they are out of school. I highly suggest using instagram analytics (a subsidiary of facebook analytics) which gives you all of the details on when your followers are active. https://www.facebook.com/help/788388387972460
Sending out regular newsletters and promoting offers through email is a great way to stay in touch with your customers and can also help to get traffic to your website. Provide useful information and links to pages on your website where they can learn more, such as through blog posts and landing pages for particular offers. Just make sure that you don`t continually bombard your readers with emails or your customers will either disengage with, delete, or unsubscribe from your emails.
