Google recommends that all websites use https:// when possible. The hostname is where your website is hosted, commonly using the same domain name that you'd use for email. Google differentiates between the "www" and "non-www" version (for example, "www.example.com" or just "example.com"). When adding your website to Search Console, we recommend adding both http:// and https:// versions, as well as the "www" and "non-www" versions.
Links still matter as part of the algorithmic secret sauce. The influence of a site’s link profile is plain to see in its search engine rankings, whether for better or worse, and changes in that link profile cause noticeable movement up or down the SERP. An SEO’s emphasis today should be on attracting links to quality content naturally, not building them en masse. (For more on proper link building today, see http://bit.ly/1XIm3vf )
The PageRank formula also contains a damping factor (d) . According to the PageRank theory, there is an imaginary surfer who is randomly clicking on links, and at some point he gets bored and eventually stops clicking. The probability that the person will continue clicking at any step is a damping factor. Thus, this factor is introduced to stop some pages having too much influence. As a result, their total vote is damped down by multiplying it by 0.85 (a generally assumed value).
Another reason is that if you're using an image as a link, the alt text for that image will be treated similarly to the anchor text of a text link. However, we don't recommend using too many images for links in your site's navigation when text links could serve the same purpose. Lastly, optimizing your image filenames and alt text makes it easier for image search projects like Google Image Search to better understand your images.
Paid search functions as an auction. Advertisers bid on keywords that are relevant to their business that can trigger the display of their ads when users search for those terms. A wide range of factors determine where an ad will be shown on the SERP. Some ads might be displayed above the organic search results (such as the Lowe’s, Craftsman, and Husqvarna examples in the “lawnmowers” SERP example above), whereas others may be shown to the right of the organic results. Some advertisers choose to limit the display of their ads to mobile searches only, whereas others exclude mobile results altogether. Some ads feature extensions, and some do not.
CTR matters because it is a metric that can be controlled by marketers. However, while Google’s emphasis on CTR should be noted, it is also important that marketers don’t get tunnel vision with improving CTR. It is not an uncommon mistake for marketers to focus primarily on improving CTR… to their detriment. Creating highly attractive ads for the sole purpose of increasing CTR could be a costly error that ultimately impact your account history, especially if the ads are misleading and result in high bounce rates.
While most of the links to your site will be added gradually, as people discover your content through search or other ways and link to it, Google understands that you'd like to let others know about the hard work you've put into your content. Effectively promoting your new content will lead to faster discovery by those who are interested in the same subject. As with most points covered in this document, taking these recommendations to an extreme could actually harm the reputation of your site.
I find that companies without a digital strategy (and many that do) don't have a clear strategic goal for what they want to achieve online in terms of gaining new customers or building deeper relationships with existing ones. And if you don't have goals with SMART digital marketing objectives you likely don't put enough resources to reach the goals and you don't evaluate through analytics whether you're achieving those goals.
