Structured data21 is code that you can add to your sites' pages to describe your content to search engines, so they can better understand what's on your pages. Search engines can use this understanding to display your content in useful (and eye-catching!) ways in search results. That, in turn, can help you attract just the right kind of customers for your business.
Black hat SEO involves techniques such as paying to post links to a website on link farms, stuffing the metadata with nonrelated keywords, and using text that is invisible to readers to attract search engines. These and many other black hat SEO tactics may boost traffic, but search engines frown on the use of such measures. Search engines may punish sites that employ these methods by reducing their page rank or delisting them from search results.
Also make sure that your blog posts are consistent with one another and that each post has the same-sized images, headings and font. Always ensure that your blog post titles don’t lead your visitors astray.  This may seem obvious, but it happens more often than you’d think. For example, if your blog post is titled “The Top 10 Places to Hike in Southern California” but the post itself talks about hiking spots all throughout the entire state of California, you’re probably going to lose visitors. After all, it’s not what they had signed on for!
Make it as easy as possible for users to go from general content to the more specific content they want on your site. Add navigation pages when it makes sense and effectively work these into your internal link structure. Make sure all of the pages on your site are reachable through links, and that they don't require an internal "search" functionality to be found. Link to related pages, where appropriate, to allow users to discover similar content.
Another way to increase traffic to your website is to get listed in free online directories and review sites. For most of these sites, your profile will have a link to your website, so actively updating these listings and getting positive reviews is likely to result in more website traffic. In addition, many directories like Yelp have strong domain authority on Google. There’s a chance that your business’s free Yelp page could rank high for relevant searches.
Firstly, a disclaimer – don’t spam Reddit and other similar sites hoping to “hit the jackpot” of referral traffic, because it’s not going to happen. Members of communities like Reddit are extraordinarily savvy to spam disguised as legitimate links, but every now and again, it doesn’t hurt to submit links that these audiences will find genuinely useful. Choose a relevant subreddit, submit your content, then watch the traffic pour in.
If you are using Responsive Web Design, use meta name="viewport" tag to tell the browser how to adjust the content. If you use Dynamic Serving, use the Vary HTTP header to signal your changes depending on the user-agent. If you are using separate URLs, signal the relationship between two URLs by tag with rel="canonical" and rel="alternate" elements.
