Naturally, business owners want to rank for lots of keywords in organic listings with their website. The challenge for webmasters and SEO is that Google doesn’t want business owners to rank for lots of keywords using autogenerated content especially when that produces A LOT of pages on a website using (for instance) a list of keyword variations page-to-page.

I’ve got by, by thinking external links to other sites should probably be on single pages deeper in your site architecture, with the pages receiving all your Google Juice once it’s been “soaked up” by the higher pages in your site structure (the home page, your category pages). This tactic is old school but I still follow it. I don’t need to think you need to worry about that, too much, in 2019.
What about other search engines that use them? Hang on while I submit my site to those 75,000 engines first [sarcasm!]. Yes, ten years ago early search engines liked looking at your meta-keywords. I’ve seen OPs in forums ponder which is the best way to write these tags – with commas, with spaces, limiting to how many characters. Forget about meta-keyword tags – they are a pointless waste of time and bandwidth.
Give people information, or even be more creative. Get people to share pictures of themselves wearing the t-shirt. Create a community of people who are interested in your product. Get a famous person to wear it and share that picture online. Do something different, do something unique. Show Google that you are different and better than the other search results.
Black hat SEO attempts to improve rankings in ways that are disapproved of by the search engines, or involve deception. One black hat technique uses hidden text, either as text colored similar to the background, in an invisible div, or positioned off screen. Another method gives a different page depending on whether the page is being requested by a human visitor or a search engine, a technique known as cloaking. Another category sometimes used is grey hat SEO. This is in between black hat and white hat approaches, where the methods employed avoid the site being penalized but do not act in producing the best content for users. Grey hat SEO is entirely focused on improving search engine rankings.
Companies that employ overly aggressive techniques can get their client websites banned from the search results. In 2005, the Wall Street Journal reported on a company, Traffic Power, which allegedly used high-risk techniques and failed to disclose those risks to its clients.[15] Wired magazine reported that the same company sued blogger and SEO Aaron Wall for writing about the ban.[16] Google's Matt Cutts later confirmed that Google did in fact ban Traffic Power and some of its clients.[17]
Put differently, to be phenomenally successful, we seek not to take static content and try to pry greater results from it; instead, we leverage the existing needs of the users, and use that knowledge to help us create the best possible user experience. That, in turn, will be rewarded with higher rankings, greater traffic, and a higher ROI from our marketing efforts.
Think, that one day, your website will have to pass a manual review by ‘Google’ – the better rankings you get, or the more traffic you get, the more likely you are to be reviewed. Know that Google, at least classes even useful sites as spammy, according to leaked documents. If you want a site to rank high in Google – it better ‘do’ something other than exist only link to another site because of a paid commission. Know that to succeed, your website needs to be USEFUL, to a visitor that Google will send you – and a useful website is not just a website, with a sole commercial intent, of sending a visitor from Google to another site – or a ‘thin affiliate’ as Google CLASSIFIES it.

Google ranks websites (relevancy aside for a moment) by the number and quality of incoming links to a site from other websites (amongst hundreds of other metrics). Generally speaking, a link from a page to another page is viewed in Google “eyes” as a vote for that page the link points to. The more votes a page gets, the more trusted a page can become, and the higher Google will rank it – in theory. Rankings are HUGELY affected by how much Google ultimately trusts the DOMAIN the page is on. BACKLINKS (links from other websites – trump every other signal.)

In 1998, two graduate students at Stanford University, Larry Page and Sergey Brin, developed "Backrub", a search engine that relied on a mathematical algorithm to rate the prominence of web pages. The number calculated by the algorithm, PageRank, is a function of the quantity and strength of inbound links.[22] PageRank estimates the likelihood that a given page will be reached by a web user who randomly surfs the web, and follows links from one page to another. In effect, this means that some links are stronger than others, as a higher PageRank page is more likely to be reached by the random web surfer.
Experience can educate you when a page is high-quality and yet receives no traffic. If the page is thin, but is not manipulative, is indeed ‘unique’ and delivers on a purpose with little obvious detectable reason to mark it down, then you can say it is a high-quality page – just with very little search demand for it. Ignored content is not the same as ‘toxic’ content.
There are some basic keyword usage rules you should follow to get started. Unique keywords should be employed on each page of your site in the areas that bots and humans normally look to reassure them that you have what they're after. This includes both the title tag and the body of your content, which leads to an important point: the pitfalls of clickbait. You may believe you're enticing more clicks by offering tantalizingly vague titles for your content, but by disguising what the page is actually about, you're opting out of some of the power of keywords.
