The world of digital marketing is as complex as it is exciting. Young entrepreneurs get into the digital marketing business as freelancers, writers, and web designers. Small businesses use lean digital marketing strategies to grow their presence online and gain new customers. SMBs become massively successful corporations by harnessing the power of enterprise digital marketing. In the modern age, every online entity must have a digital marketing strategy to be competitive in the internet marketplace. However, digital marketing trends are always changing. What works today may be obsolete tomorrow. Furthermore, the popular terms of the month can seem outdated in the next.
QUOTE: “News and current events: news about important topics such as international events, business, politics, science, technology, etc. Keep in mind that not all news articles are necessarily considered YMYL (e.g., sports, entertainment, and everyday lifestyle topics are generally not YMYL). Please use your judgment and knowledge of your locale. ● Civics, government, and law: information important to maintaining an informed citizenry, such as information about voting, government agencies, public institutions, social services, and legal issues (e.g., divorce, child custody, adoption, creating a will, etc.). ● Finance: financial advice or information regarding investments, taxes, retirement planning, loans, banking, or insurance, particularly webpages that allow people to make purchases or transfer money online. ● Shopping: information about or services related to research or purchase of goods/services, particularly webpages that allow people to make purchases online. ● Health and safety: advice or information about medical issues, drugs, hospitals, emergency preparedness, how dangerous an activity is, etc. ● Groups of people: information about or claims related to groups of people, including but not limited to those grouped on the basis of race or ethnic origin, religion, disability, age, nationality, veteran status, sexual orientation, gender or gender identity. ● Other: there are many other topics related to big decisions or important aspects of people’s lives which thus may be considered YMYL, such as fitness and nutrition, housing information, choosing a college, finding a job, etc.” Google Search Quality Evaluator Guidelines 2019
I prefer simple SEO techniques and ones that can be measured in some way. I have never just wanted to rank for competitive terms; I have always wanted to understand at least some of the reasons why a page ranked for these key phrases. I try to create a good user experience for humans AND search engines. If you make high-quality text content relevant and suitable for both these audiences, you’ll more than likely find success in organic listings and you might not ever need to get into the technical side of things, like redirects and search engine friendly URLs.
QUOTE: “Many websites are eager to tell users how great they are. Some webmasters have read these rating guidelines and write “reviews” on various review websites. But for Page Quality rating, you must also look for outside, independent reputation information about the website. When the website says one thing about itself, but reputable external sources disagree with what the website says, trust the external sources. ” Google Search Quality Evaluator Guidelines 2019
QUOTE: “If you have comments on your site, and you just let them run wild, you don’t moderate them, they’re filled with spammers or with people who are kind of just abusing each other for no good reason, then that’s something that might kind of pull down the overall quality of your website where users when they go to those pages might say, well, there’s some good content on top here, but this whole bottom part of the page, this is really trash. I don’t want to be involved with the website that actively encourages this kind of behavior or that actively promotes this kind of content. And that’s something where we might see that on a site level, as well.” John Mueller, Google 2016
In short, nobody is going to advise you to create a poor UX, on purpose, in light of Google’s algorithms and human quality raters who are showing an obvious interest in this stuff. Google is rating mobile sites on what it classes is frustrating UX – although on certain levels what Google classes as ‘UX’ might be quite far apart from what a UX professional is familiar with in the same ways as Google’s mobile rating tools differ from, for instance,  W3c Mobile testing tools.
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. 
Both require knowing your audience. To succeed at both strategies, you must have a good understanding of your audience and how they act. By using buyer personas and psychographic segmentation, you can get to know your audience, discover what their needs are, and what they are searching for. Then you can create valuable content that shows up when they go looking for solutions related to your brand.
If you are just starting out, don’t think you can fool Google about everything all the time. Google has VERY probably seen your tactics before. So, it’s best to keep your plan simple. GET RELEVANT. GET REPUTABLE. Aim for a healthy, satisfying visitor experience. If you are just starting out – you may as well learn how to do it within Google’s Webmaster Guidelines first. Make a decision, early, if you are going to follow Google’s guidelines, or not, and stick to it. Don’t be caught in the middle with an important project. Do not always follow the herd.
Length of site domain registration; (I don’t see much benefit ON IT”S OWN even knowing “Valuable (legitimate) domains are often paid for several years in advance, while doorway (illegitimate) domains rarely are used for more than a year.”) – paying for a domain in advance just tells others you don’t want anyone else using this domain name, it is not much of an indication that you’re going to do something Google cares about).
QUOTE: “Many SEOs and other agencies and consultants provide useful services for website owners, including: Review of your site content or structure – Technical advice on website development: for example, hosting, redirects, error pages, use of JavaScript – Content development – Management of online business development campaigns – Keyword research – SEO training – Expertise in specific markets and geographies.” Google Webmaster Guidelines, 2020

This helpful tool scans your backlink profile and turns up a list of contact information for the links and domains you'll need to reach out to for removal. Alternatively, the tool also allows you to export the list if you wish to disavow them using Google's tool. (Essentially, this tool tells Google not to take these links into account when crawling your site.)

QUOTE: “How do I move from one domain to another domain and try to preserve the rankings as best as possible?…do a 301 permanent redirect to the new location (assuming that you’re you’re moving for all time and eternity so this is the good case for a permanent or 301 redirect if you were planning to undo this later or it’s temporary then you’d use a 302 redirect)…. search engines should be able to follow the trail of all the 301 redirects” Matt Cutts, Google
An SEO meta description is a brief description of content found on a web page. The meta description is shown to users in search engine results pages to help them decide which search result to click on. Meta descriptions are not a ranking factor in the eyes of a search engine, but they can influence how many people click on a result -- which directly affects the result's organic ranking.
QUOTE: “What makes a page spammy?: “Hidden text or links – may be exposed by selecting all page text and scrolling to the bottom (all text is highlighted), disabling CSS/Javascript, or viewing source code. Sneaky redirects – redirecting through several URLs, rotating destination domains cloaking with JavaScript redirects and 100% frame. Keyword stuffing – no percentage or keyword density given; this is up to the rater. PPC ads that only serve to make money, not help users. Copied/scraped content and PPC ads. Feeds with PPC ads. Doorway pages – multiple landing pages that all direct user to the same destination. Templates and other computer-generated pages mass-produced, marked by copied content and/or slight keyword variations. Copied message boards with no other page content. Fake search pages with PPC ads. Fake blogs with PPC ads, identified by copied/scraped or nonsensical spun content. Thin affiliate sites that only exist to make money, identified by checkout on a different domain, image properties showing origination at another URL, lack of original content, different WhoIs registrants of the two domains in question. Pure PPC pages with little to no content. Parked domains” Miranda Miller, SEW, 2011
However, we do expect websites of large companies and organizations to put a great deal of effort into creating a good user experience on their website, including having helpful SC. For large websites, SC may be one of the primary ways that users explore the website and find MC, and a lack of helpful SC on large websites with a lot of content may be a reason for a Low rating.
The SEO starter guide describes much of what your SEO will do for you. Although you don't need to know this guide well yourself if you're hiring a professional to do the work for you, it is useful to be familiar with these techniques, so that you can be aware if an SEO wants to use a technique that is not recommended or, worse, strongly discouraged.
