By relying so much on factors such as keyword density which were exclusively within a webmaster's control, early search engines suffered from abuse and ranking manipulation. To provide better results to their users, search engines had to adapt to ensure their results pages showed the most relevant search results, rather than unrelated pages stuffed with numerous keywords by unscrupulous webmasters. This meant moving away from heavy reliance on term density to a more holistic process for scoring semantic signals.[13] Since the success and popularity of a search engine is determined by its ability to produce the most relevant results to any given search, poor quality or irrelevant search results could lead users to find other search sources. Search engines responded by developing more complex ranking algorithms, taking into account additional factors that were more difficult for webmasters to manipulate. In 2005, an annual conference, AIRWeb (Adversarial Information Retrieval on the Web), was created to bring together practitioners and researchers concerned with search engine optimization and related topics.[14]


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.
Ever since its April 2015 update, Google is now taking the user's mobile experience into consideration in its search results. This means that when a user is doing a search on a mobile device, Google's search results will favor websites that are mobile friendly over the ones that aren't. If you want to capture that mobile search audience, you will need to have a mobile version of your website in addition to your desktop version.

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).
Creating high quality content takes a significant amount of at least one of the following: time, effort, expertise, and talent/skill. Content should be factually accurate, clearly written, and comprehensive. So, for example, if you describe your page as a recipe, provide a complete recipe that is easy to follow, rather than just a set of ingredients or a basic description of the dish.
After a while, Google will know about your pages, and keep the ones it deems ‘useful’ – pages with original content, or pages with a lot of links to them. The rest will be de-indexed. Be careful – too many low-quality pages on your site will impact your overall site performance in Google. Google is on record talking about good and bad ratios of quality content to low-quality 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.
NOTE, in 2019, the HTML title element you choose for your page, may not be what Google chooses to include in your SERP snippet. The search snippet title and description is very much QUERY & DEVICE dependant these days. Google often chooses what it thinks is the most relevant title for your search snippet, and it can use information from your page, or in links to that page, to create a very different SERP snippet title.
Thick & Unique Content – There is no magic number in terms of word count, and if you have a few pages of content on your site with a handful to a couple hundred words you won’t be falling out of Google’s good graces, but in general recent Panda updates in particular favor longer, unique content. If you have a large number (think thousands) of extremely short (50-200 words of content) pages or lots of duplicated content where nothing changes but the page’s title tag and say a line of text, that could get you in trouble. Look at the entirety of your site: are a large percentage of your pages thin, duplicated and low value? If so, try to identify a way to “thicken” those pages, or check your analytics to see how much traffic they’re getting, and simply exclude them (using a noindex meta tag) from search results to keep from having it appear to Google that you’re trying to flood their index with lots of low value pages in an attempt to have them rank.
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.
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.
QUOTE: “To summarize, a lack of helpful SC may be a reason for a Low quality rating, depending on the purpose of the page and the type of website. We have different standards for small websites which exist to serve their communities versus large websites with a large volume of webpages and content. For some types of “webpages,” such as PDFs and JPEG files, we expect no SC at all.” Google Search Quality Evaluator Guidelines 2017

Moreover: if you don’t have to, don’t change your URLs. Even if your URLs aren’t “pretty,” if you don’t feel as though they’re negatively impacting users and your business in general, don’t change them to be more keyword focused for “better SEO.” If you do have to change your URL structure, make sure to use the proper (301 permanent) type of redirect. This is a common mistake businesses make when they redesign their websites.

SEO is not an appropriate strategy for every website, and other Internet marketing strategies can be more effective, such as paid advertising through pay per click (PPC) campaigns, depending on the site operator's goals. Search engine marketing (SEM) is the practice of designing, running and optimizing search engine ad campaigns.[56] Its difference from SEO is most simply depicted as the difference between paid and unpaid priority ranking in search results. Its purpose regards prominence more so than relevance; website developers should regard SEM with the utmost importance with consideration to visibility as most navigate to the primary listings of their search.[57] A successful Internet marketing campaign may also depend upon building high quality web pages to engage and persuade, setting up analytics programs to enable site owners to measure results, and improving a site's conversion rate.[58] In November 2015, Google released a full 160 page version of its Search Quality Rating Guidelines to the public,[59] which revealed a shift in their focus towards "usefulness" and mobile search. In recent years the mobile market has exploded, overtaking the use of desktops, as shown in by StatCounter in October 2016 where they analyzed 2.5 million websites and found that 51.3% of the pages were loaded by a mobile device [60]. Google has been one of the companies that are utilizing the popularity of mobile usage by encouraging websites to use their Google Search Console, the Mobile-Friendly Test, which allows companies to measure up their website to the search engine results and how user-friendly it is.
Additionally, there are many situations where PPC (a component of SEM) makes more sense than SEO. For example, if you are first launching a site and you want immediate visibility, it is a good idea to create a PPC campaign because it takes less time than SEO, but it would be unwise to strictly work with PPC and not even touch search engine optimization.
QUOTE: “Medium pages achieve their purpose and have neither high nor low expertise, authoritativeness, and trustworthiness. However, Medium pages lack the characteristics that would support a higher quality rating. Occasionally, you will find a page with a mix of high and low quality characteristics. In those cases, the best page quality rating may be Medium.” Google Quality Evaluator Guidelines, 2017
Link text is the visible text inside a link. This text tells users and Google something about the page you're linking to. Links on your page may be internal—pointing to other pages on your site—or external—leading to content on other sites. In either of these cases, the better your anchor text is, the easier it is for users to navigate and for Google to understand what the page you're linking to is about.
ensure redirected domains redirect through a canonical redirect and this too has any chains minimised, although BE SURE to audit the backlink profile for any redirects you point at a page as with reward comes punishment if those backlinks are toxic (another example of Google opening up the war that is technical seo on a front that isn’t, and in fact is converse, to building backlinks to your site).
Gain an understanding of search engine algorithms and how they affect organic search results and websites. Building on this knowledge, you’ll learn the key elements for creating an effective SEO strategy, including how to select keywords and perform keyword research; consumer psychology and search behavior; and how to conduct on-page SEO analysis to identify opportunities to improve a website’s search optimization.
******” Quote from Google: One other specific piece of guidance we’ve offered is that low-quality content on some parts of a website can impact the whole site’s rankings, and thus removing low-quality pages, merging or improving the content of individual shallow pages into more useful pages, or moving low-quality pages to a different domain could eventually help the rankings of your higher-quality content.

In March 2006, KinderStart filed a lawsuit against Google over search engine rankings. KinderStart's website was removed from Google's index prior to the lawsuit, and the amount of traffic to the site dropped by 70%. On March 16, 2007, the United States District Court for the Northern District of California (San Jose Division) dismissed KinderStart's complaint without leave to amend, and partially granted Google's motion for Rule 11 sanctions against KinderStart's attorney, requiring him to pay part of Google's legal expenses.[70][71]
If you're a regular blogger, these are probably the topics you blog about most frequently. Or perhaps they're the topics that come up the most in sales conversations. Put yourself in the shoes of your buyer personas -- what types of topics would your target audience search that you'd want your business to get found for? If you were a company like HubSpot, for example -- selling marketing software (which happens to have some awesome SEO tools ... but I digress ... you might have general topic buckets like:
Once you have your keyword list, the next step is actually implementing your targeted keywords into your site’s content. Each page on your site should be targeting a core term, as well as a “basket” of related terms. In his overview of the perfectly optimized page, Rand Fishkin offers a nice visual of what a well (or perfectly) optimized page looks like:
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.

QUOTE: “We do use it for ranking, but it’s not the most critical part of a page. So it’s not worthwhile filling it with keywords to hope that it works that way. In general, we try to recognise when a title tag is stuffed with keywords because that’s also a bad user experience for users in the search results. If they’re looking to understand what these pages are about and they just see a jumble of keywords, then that doesn’t really help.” John Mueller, Google 2016
I think ranking in organic listings is a lot about trusted links making trusted pages rank, making trusted links making trusted pages rank ad nauseam for various keywords. Some pages can pass trust to another site; some pages cannot. Some links can. Some cannot. Some links are trusted enough to pass ranking signals to another page. Some are not. YOU NEED LINKS FROM TRUSTED PAGES IF YOU WANT TO RANK AND AVOID PENALTIES & FILTERS.
QUOTE: “I think that’s always an option. Yeah. That’s something that–I’ve seen sites do that across the board,not specifically for blogs, but for content in general, where they would regularly go through all of their content and see, well, this content doesn’t get any clicks, or everyone who goes there kind of runs off screaming.” John Mueller, Google 
A poor 404 page and user interaction with it, can only lead to a ‘poor user experience’ signal at Google’s end, for a number of reasons. I will highlight a poor 404 page in my audits and actually programmatically look for signs of this issue when I scan a site. I don’t know if Google looks at your site that way to rate it e.g. algorithmically determines if you have a good 404 page – or if it is a UX factor, something to be taken into consideration further down the line – or purely to get you thinking about 404 pages (in general) to help prevent Google wasting resources indexing crud pages and presenting poor results to searchers. I think rather that any rating would be a second order scoring including data from user activity on the SERPs – stuff we as SEO can’t see.

SEO may generate an adequate return on investment. However, search engines are not paid for organic search traffic, their algorithms change, and there are no guarantees of continued referrals. Due to this lack of guarantees and certainty, a business that relies heavily on search engine traffic can suffer major losses if the search engines stop sending visitors.[61] Search engines can change their algorithms, impacting a website's placement, possibly resulting in a serious loss of traffic. According to Google's CEO, Eric Schmidt, in 2010, Google made over 500 algorithm changes – almost 1.5 per day.[62] It is considered a wise business practice for website operators to liberate themselves from dependence on search engine traffic.[63] In addition to accessibility in terms of web crawlers (addressed above), user web accessibility has become increasingly important for SEO.
QUOTE: “Over time, we’ve seen sites try to maximize their “search footprint” without adding clear, unique value. These doorway campaigns manifest themselves as pages on a site, as a number of domains, or a combination thereof. To improve the quality of search results for our users, we’ll soon launch a ranking adjustment to better address these types of pages. Sites with large and well-established doorway campaigns might see a broad impact from this change.” Google 2015
A page title that is highly relevant to the page it refers to will maximise usability, search engine ranking performance and user experience ratings as Google measures these. It will probably be displayed in a web browser’s window title bar, bookmarks and in clickable search snippet links used by Google, Bing & other search engines. The title element is the “crown” of a web page with important keyword phrase featuring AT LEAST ONCE within it.
Some pages are designed to manipulate users into clicking on certain types of links through visual design elements, such as page layout, organization, link placement, font color, images, etc. We will consider these kinds of pages to have deceptive page design. Use the Lowest rating if the page is deliberately designed to manipulate users to click on Ads, monetized links, or suspect download links with little or no effort to provide helpful MC.
A breadcrumb is a row of internal links at the top or bottom of the page that allows visitors to quickly navigate back to a previous section or the root page. Many breadcrumbs have the most general page (usually the root page) as the first, leftmost link and list the more specific sections out to the right. We recommend using breadcrumb structured data markup28 when showing breadcrumbs.
