To avoid undesirable content in the search indexes, webmasters can instruct spiders not to crawl certain files or directories through the standard robots.txt file in the root directory of the domain. Additionally, a page can be explicitly excluded from a search engine's database by using a meta tag specific to robots (usually ). When a search engine visits a site, the robots.txt located in the root directory is the first file crawled. The robots.txt file is then parsed and will instruct the robot as to which pages are not to be crawled. As a search engine crawler may keep a cached copy of this file, it may on occasion crawl pages a webmaster does not wish crawled. Pages typically prevented from being crawled include login specific pages such as shopping carts and user-specific content such as search results from internal searches. In March 2007, Google warned webmasters that they should prevent indexing of internal search results because those pages are considered search spam.[47]
Tablet - We consider tablets as devices in their own class, so when we speak of mobile devices, we generally do not include tablets in the definition. Tablets tend to have larger screens, which means that, unless you offer tablet-optimized content, you can assume that users expect to see your site as it would look on a desktop browser rather than on a smartphone browser.
QUOTE: “There’s probably always gonna be a little bit of room for keyword research because you’re kind of providing those words to users. And even if search engines are trying to understand more than just those words, showing specific words to users can make it a little bit easier for them to understand what your pages are about and can sometimes drive a little bit of that conversion process.  So I don’t see these things going away completely but I’m sure search engines will get better over time to understand more than just the words on a page.” John Mueller, Google 2020
QUOTE: “Important: The Lowest rating is appropriate if all or almost all of the MC (main content) on the page is copied with little or no time, effort, expertise, manual curation, or added value for users. Such pages should be rated Lowest, even if the page assigns credit for the content to another source.” – Google Search Quality Evaluator Guidelines 2019

You might have heard about Google Panda and Google Penguin – two major updates to Google’s search algorithm. Google also makes minor changes to its algorithm 500-600 times a year. We update the Yoast SEO plugin every 2 weeks. That way you’re sure that your website is optimized for Google’s most recent version of its algorithm. Updates and upgrades on our Premium plugin are only available with a valid subscription.
QUOTE: “An infinite number of niches are waiting for someone to claim them. I’d ask yourself where you want to be, and see if you can find a path from a tiny specific niche to a slightly bigger niche and so on, all the way to your desired goal. Sometimes it’s easier to take a series of smaller steps instead of jumping to your final goal in one leap.” Matt Cutts, Google 2006
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
QUOTE: “(Google Panda) measures the quality of a site pretty much by looking at the vast majority of the pages at least. But essentially allows us to take quality of the whole site into account when ranking pages from that particular site and adjust the ranking accordingly for the pages. So essentially, if you want a blunt answer, it will not devalue, it will actually demote. Basically, we figured that site is trying to game our systems, and unfortunately, successfully. So we will adjust the rank. We will push the site back just to make sure that it’s not working anymore.”  Gary Illyes, Google 2016
QUOTE: “Starting April 21 (2015), we will be expanding our use of mobile-friendliness as a ranking signal. This change will affect mobile searches in all languages worldwide and will have a significant impact in our search results. Consequently, users will find it easier to get relevant, high-quality search results that are optimized for their devices”. GOOGLE
QUOTE: “The easiest thing is think about what people are gonna type to want to find your site so we had somebody come to a conference and say I want to show up for (Keyword) and we said well have you put the (Keyword) on your page anywhere at all and he hadn’t and sometimes just very simple stuff like that really helps think about what users are gonna type to find your page and then just make sure those keywords are on the page.” Matt Cutts, Google 2013

QUOTE: “We are a health services comparison website…… so you can imagine that for the majority of those pages the content that will be presented in terms of the clinics that will be listed looking fairly similar right and the same I think holds true if you look at it from the location …… we’re conscious that this causes some kind of content duplication so the question is is this type … to worry about? ” Webmaster Question, 2017
Optimization techniques are highly tuned to the dominant search engines in the target market. The search engines' market shares vary from market to market, as does competition. In 2003, Danny Sullivan stated that Google represented about 75% of all searches.[64] In markets outside the United States, Google's share is often larger, and Google remains the dominant search engine worldwide as of 2007.[65] As of 2006, Google had an 85–90% market share in Germany.[66] While there were hundreds of SEO firms in the US at that time, there were only about five in Germany.[66] As of June 2008, the market share of Google in the UK was close to 90% according to Hitwise.[67] That market share is achieved in a number of countries.

It’s important to note that Google is responsible for the majority of the search engine traffic in the world. This may vary from one industry to another, but it’s likely that Google is the dominant player in the search results that your business or website would want to show up in, but the best practices outlined in this guide will help you to position your site and its content to rank in other search engines, as well.


QUOTE: “Content which is copied, but changed slightly from the original. This type of copying makes it difficult to find the exact matching original source. Sometimes just a few words are changed, or whole sentences are changed, or a “find and replace” modification is made, where one word is replaced with another throughout the text. These types of changes are deliberately done to make it difficult to find the original source of the content. We call this kind of content “copied with minimal alteration.” Google Search Quality Evaluator Guidelines March 2017
Your website is the “hub” of your online brand – so, it’s important to have regular checkups to ensure everything is in order. It’s also important to note that your website is a living digital property, it’s typically not stagnant for long periods of time. In any given year, content is added and/or removed from your site. It is for this reason that audits should occur on a regular basis. We recommend that websites be audited at a minimum of once per year. That allows your teams to fix critical issues as they arise.
