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!
What is Search Engine Optimization (also known as SEO)? A broad definition is that search engine optimization is the art and science of making web pages attractive to search engines. More narrowly, SEO seeks to tweak particular factors known to affect search engine standing to make certain pages more attractive to search engines than other web pages that are vying for the same keywords or keyword phrases.

Keep resources crawlable. Blocking page resources can give Google an incomplete picture of your website. This often happens when your robots.txt file is blocking access to some or all of your page resources. If Googlebot doesn't have access to a page's resources, such as CSS, JavaScript, or images, we may not detect that it's built to display and work well on a mobile browser. In other words, we may not detect that the page is "mobile-friendly," and therefore not properly serve it to mobile searchers.
Usually Search-engines automatically crawl your articles if it is high-quality but you should also try to submit your blog to search engines like Google, Bing, and Ask etc. Search engines like Google have already simplified the way of submitting your content. Google Webmaster Tools makes it easy for every webmaster to get their website crawled faster.
You should build a website to benefit your users, and any optimization should be geared toward making the user experience better. One of those users is a search engine, which helps other users discover your content. Search Engine Optimization is about helping search engines understand and present content. Your site may be smaller or larger than our example site and offer vastly different content, but the optimization topics we discuss below should apply to sites of all sizes and types. We hope our guide gives you some fresh ideas on how to improve your website, and we'd love to hear your questions, feedback, and success stories in the Google Webmaster Help Forum1.

Thanks for the great post. I am confused about the #1 idea about wikipedia ded links…it seems like you didn’t finish what you were supposed to do with the link once you found it. You indicated to put the dead link in ahrefs and you found a bunch of links for you to contact…but then what? What do you contact them about and how do you get your page as the link? I’m obviously not getting something 🙁

Wow, brilliant strategy! I am thrilled to learn something new and effective that isn’t “black hat”. And yes, this does require work, but that’s precisely what it should require. I would rather see sites ranking high because they contribute terrific content (i.e. useful/interesting infographics) to their niche vs. the person exploiting the latest loophole. But that’s just my opinion 🙂
Meta tags. Meta tags still play a vital role in SEO. If you type any keyword into a search engine, you’ll see how that keyword is reflected in the title for that page. Google looks at your page title as a signal of relevance for that keyword. The same holds true for the description of that page. (Don't worry about the keyword title tag -- Google has publicly said that it doesn't pay attention to that tag, since it has been abused by webmasters and all those trying to rank for certain keywords.) 

Thanks to decreasing attention spans, it should come as no surprise that people don’t have the patience to wait more than a few seconds for a site to load. According to a study by Akamai, 40% of people leave a site if it takes more than three seconds to load. Keep users on your website by making sure that it’s running as fast as possible. A few simple ways that you can increase website speed are by reducing the number of plugins on your site, compressing images and enabling browser caching.
Nothing looks sloppier than websites that don’t abide by any sort of style guide. Is your blog section a complete deviation from your website? If so, this very well could throw off your visitors and decrease engagement. Instead, make sure that all of your web pages are consistent in design, font and even voice. For instance, if you use a very formal tone on your homepage, but a super casual tone in your blog posts, this could highlight brand inconsistency.
Having an industry influencer publish a blog post on your site or turning an interview with them into a blog post can help to drive traffic both through organic search but also via that influencer promoting the content to their audience (see the backlinks section above). This can also help to add more variety to your content and show your visitors that you are active in your field.

Historical refreshes of content is a good thing, especially if some of your content has expired. Note, this does not mean re-doing your content; simply refreshing it to bring it current if it isn't already evergreen content. Look at ways you can update outdated content on your site to drive more traffic through visibility on search engines like Google.

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.”
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.
Current search engine optimization focuses on techniques such as making sure that each web page has appropriate title tags and that the content is not "thin" or low-quality. High-quality content is original, authoritative, factual, grammatically correct, and engaging to users. Poorly edited articles with spelling and grammatical errors will be demoted by search engines. For more information on thin content see More Guidance on Building High-quality Sites.
It’s an awesome post which I like the most and commenting here for the first time. I’m Abhishek founder of CouponMaal want to know more like you’ve said above in the points relaunch your old posts. Here I want to know is there any difference between changing the date, time and year while we’re relaunching old post OR we should relaunch the old post with the previous date, time and year. I mean it matters or not.
Spider-driven search engines such as Google®, Yahoo!® and MSN® use "robots" or "crawlers" to score websites across the Internet. Robots "spider/crawl" each site and "score" pages based on how relevant they are. A website's score or placement within a spider driven search engine is derived from hundreds of variables such as link popularity, density and frequency of keywords in page content, HTML code, site themes and more. You will want to focus many criteria in your SEO strategy to position yourself well among the major search engines. Here are two of the most influential factors:
WOW. I consider myself a total newbie to SEO, but I’ve been working on my Squarespace site for my small business for about 3 years and have read dozens of articles on how to improve SEO. So far, this has been the MOST USEFUL and information-packed resource I’ve found so far. I’m honestly shocked that this is free to access. I haven’t even completely consumed this content yet (I’ve bookmarked it to come back to!) but I’ve already made some significant changes to my SEO strategy, including adding a couple of infographics to blog posts, changing my internal and external linking habits, editing meta descriptions, and a bunch more. Thanks for all the time and passion you’ve out into this.
