Anchor Text is the visible text on a link or button that you can click on. Google uses this text to determine what the linked page is about. For example, if you set "Learn More About Bike Repairs" as the Anchor Text for the link that goes to your repairs page, it tells Google that the linked page is most likely about bike repairs. When building your site with our site builder, make your Anchor Text as descriptive as possible and avoid using generic Anchor Text like "Click Here" as this doesn't help Google categorize your pages whatsoever.
Do you regularly publish helpful, useful articles, videos or other types of media that are popular and well produced? Do you write for actual human beings rather than the search engine itself? Well, you should. Latest research from Searchmetrics on ranking factors indicates that Google is moving further towards longer-form content that understands a visitor’s intention as a whole, instead of using keywords based on popular search queries to create content.
SEM is a broader term than SEO, and is used to encompass different options available to use a search engine’s technology, including paid ads. SEM is often used to describe acts associated with researching, submitting and positioning a website within search engines. It includes things such as search engine optimization, paid listings and other search-engine related services and functions that will increase exposure and traffic to your Web site.
QUOTE: “7.4.3 Automatically Generated Main Content Entire websites may be created by designing a basic template from which hundreds or thousands of pages are created, sometimes using content from freely available sources (such as an RSS feed or API). These pages are created with no or very little time, effort, or expertise, and also have no editing or manual curation. Pages and websites made up of autogenerated content with no editing or manual curation, and no original content or value added for users, should be rated Lowest.” Google Search Quality Evaluator Guidelines 2017
Because someone who is looking for something that specific is probably a much more qualified searcher for your product or service (presuming you're in the blogging space) than someone looking for something really generic. And because long-tail keywords tend to be more specific, it's usually easier to tell what people who search for those keywords are really looking for. Someone searching for the head term "blogging," on the other hand, could be searching it for a whole host of reasons unrelated to your business.
