QUOTE: “Google Webmaster Tools notice of detected doorway pages on xxxxxxxx – Dear site owner or webmaster of xxxxxxxx, We’ve detected that some of your site’s pages may be using techniques that are outside Google’s Webmaster Guidelines. Specifically, your site may have what we consider to be doorway pages – groups of “cookie cutter” or low-quality pages. Such pages are often of low value to users and are often optimized for single words or phrases in order to channel users to a single location. We believe that doorway pages typically create a frustrating user experience, and we encourage you to correct or remove any pages that violate our quality guidelines. Once you’ve made these changes, please submit your site for reconsideration in Google’s search results. If you have any questions about how to resolve this issue, please see our Webmaster Help Forum for support.” Google Search Quality Team, 2011
Many blogging software packages automatically nofollow user comments, but those that don't can most likely be manually edited to do this. This advice also goes for other areas of your site that may involve user-generated content, such as guest books, forums, shout-boards, referrer listings, etc. If you're willing to vouch for links added by third parties (for example, if a commenter is trusted on your site), then there's no need to use nofollow on links; however, linking to sites that Google considers spammy can affect the reputation of your own site. The Webmaster Help Center has more tips on avoiding comment spam40, for example by using CAPTCHAs and turning on comment moderation.
QUOTE: “While, as a whole, web usability has improved over these past several years, history repeats and designers make the same mistakes over and over again. Designers and marketers continuously need to walk a line between providing a good user experience and increasing advertising revenue. There is no “correct” answer or golden format for designers to use in order to flawlessly reach audiences; there will inevitably always be resistance to change and a desire for convention and predictability. That said, if, over the course of over ten years, users are still lamenting about the same problems, it’s time we start to take them seriously.”  Therese Fessenden, Nielsen Norman Group 2017
You pay each time a user clicks on an SEM result. You pay nothing when a user clicks on an SEO result. SEM results are paid placements, and your brand is charged each time a user clicks on the result. Therefore, you must have a budget for continually showing SEM ads and using this form of PPC lead generation. On the flip side, you are never charged when a user clicks on an organic search result.
QUOTE: “You heard right there is no duplicate content penalty… I would avoid talking about duplicate content penalties for spam purposes because then it’s not about duplicate content then it’s about generating in a very often in an automated way content that is not so much duplicated as kind of fast and scraped from multiple places and then potentially probably monetized in some way or another and it just doesn’t serve any purpose other than to gain traffic redirect traffic maybe make some money for the person who created it this is not about content that gets really sort of created for any kind of reason other than just to be there so I person I don’t think about it as duplicate content there is just this disparity it’s the same thing as saying that maybe we created gibberish is some sort of a duplicate content of words but otherwise also exists like I I would really separate those two issues because the things that Aamon led in with URLs generated on WordPress and the things they were going to discuss today later maybe about e-commerce sites and so on I wouldn’t want people to confuse those two.”  Andrey Lipattsev, Google 2016
Are you just launching your first website and creating your initial online footprint to promote your product or service? Then you’ll likely need immediate visibility in search until you build up your organic credibility. With a strategic PPC campaign, you'll be able to achieve this. What you shouldn't do, though, is rely strictly on PPC over the long-term while ignoring organic SEO. You still need to create great content that visitors will want to engage with once they get to your website.

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.
I was used to work with Tools like Sistrix, Ahrefs or Searchmetrics and did not know about SE Ranking before. But those tools were too cost-intensive for a small and quick start into SEO so I tried it out and I am quite satisfied with it. I like the ability to pay for certain services with credits, as I am not using them on a very frequent level, so it actually gives me greater flexibility to only use them when needed and not paying for them even when not using them.
A satisfying UX is can help your rankings, with second-order factors taken into consideration. A poor UX can seriously impact your human-reviewed rating, at least. Google’s punishing algorithms probably class pages as something akin to a poor UX if they meet certain detectable criteria e.g. lack of reputation or old-school SEO stuff like keyword stuffing a site.
All you need to notice from this kind of articles is what I & most of the others newbies focusing on the SEO link-building. I have seen many bloggers spending time on different ways of SEO link building instead of providing the value to the content and its social promotions. You may call it ignoring the Google, but we all know that the Google bot doesn’t ignore anchored dofollow or nofollow backlinks to calculate your PageRank.
The errors in technical SEO are often not obvious, and therefore one of the most popular. Mistakes in robots.txt and 404 pages, pagination and canonical URLs, hreflang tags and 301 redirects, http vs https and www vs non www versions: each of them can seriously spoil all efforts to promote the site. One quality SEO website analysis is enough to solve all the main problems in this part forever.
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: “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).

Note that Google is pretty good these days at removing any special characters you have in your page title – and I would be wary of trying to make your title or Meta Description STAND OUT using special characters. That is not what Google wants, evidently, and they do give you a further chance to make your search snippet stand out with RICH SNIPPETS and SCHEMA mark-up.
QUOTE – “So it’s not that our systems will look at your site and say oh this was submitted by a user therefore the site owner has like no no control over what’s happening here but rather we look at it and say well this is your website this is what you want to have indexed you kind of stand for the content that you’re providing there so if you’re providing like low quality user-generated content for indexing then we’ll think well this website is about low quality content and spelling errors don’t necessarily mean that it’s low quality but obviously like it can go in all kinds of weird directions with user-generated content…” John Mueller, Google 2019
The higher the search volume for a given keyword or keyword phrase, the more work is typically required to achieve higher rankings. This is often referred to as keyword difficulty and occasionally incorporates SERP features; for example, if many SERP features (like featured snippets, knowledge graph, carousels, etc) are clogging up a keyword’s result page, difficulty will increase. Big brands often take up the top 10 results for high-volume keywords, so if you’re just starting out on the web and going after the same keywords, the uphill battle for ranking can take years of effort.
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 2020.
QUOTE: “The purpose of a page is the reason or reasons why the page was created. Every page on the Internet is created for a purpose, or for multiple purposes. Most pages are created to be helpful for users, thus having a beneficial purpose. Some pages are created merely to make money, with little or no effort to help users. Some pages are even created to cause harm to users. The first step in understanding a page is figuring out its purpose.” Google Search Quality Evaluator Guidelines 2019
Learn the steps of Internet analysis, if you want to learn Internet marketing for free. For anyone who knows the basics of social media, search engine optimization (SEO), Google news and website building blocks, then you can likely learn Internet marketing on your own. A big part of marketing is understanding your competitors, data and market analysis.
You may not want certain pages of your site crawled because they might not be useful to users if found in a search engine's search results. If you do want to prevent search engines from crawling your pages, Google Search Console has a friendly robots.txt generator to help you create this file. Note that if your site uses subdomains and you wish to have certain pages not crawled on a particular subdomain, you'll have to create a separate robots.txt file for that subdomain. For more information on robots.txt, we suggest this Webmaster Help Center guide on using robots.txt files13.
