Having a different description meta tag for each page helps both users and Google, especially in searches where users may bring up multiple pages on your domain (for example, searches using the site: operator). If your site has thousands or even millions of pages, hand-crafting description meta tags probably isn't feasible. In this case, you could automatically generate description meta tags based on each page's content.

It might be awkward, but please don't scroll past this. This Monday we humbly ask you to defend Wikipedia's independence. Our 2019 fundraiser is coming to a close. 98% of our readers don't give; they look the other way. If you are an exceptional reader who already donated, we sincerely thank you. If all our readers donated just $2.75 today, Wikipedia could keep thriving for years. Most people donate for a simple reason—because Wikipedia is useful. If Wikipedia gave you $2.75 worth of knowledge this year, take a minute to secure its future with a gift to the Wikimedia Endowment. Show the volunteers who bring you reliable, neutral information that their work matters. Thank you.
An SEO technique is considered white hat if it conforms to the search engines' guidelines and involves no deception. As the search engine guidelines[18][19][52] are not written as a series of rules or commandments, this is an important distinction to note. White hat SEO is not just about following guidelines but is about ensuring that the content a search engine indexes and subsequently ranks is the same content a user will see. White hat advice is generally summed up as creating content for users, not for search engines, and then making that content easily accessible to the online "spider" algorithms, rather than attempting to trick the algorithm from its intended purpose. White hat SEO is in many ways similar to web development that promotes accessibility,[53] although the two are not identical.

Over the past year or two, we've also seen Google begin to fundamentally alter how its search algorithm works. Google, as with many of the tech giants, has begun to bill itself as an artificial intelligence (AI) and machine learning (ML) company rather than as a search company. AI tools will provide a way to spot anomalies in search results and collect insights. In essence, Google is changing what it considers its crown jewels. As the company builds ML into its entire product stack, its core search product has begun to behave a lot differently. This is heating up the cat-and-mouse game of SEO and sending the industry chasing after Google once again.
The last piece of the complicated SEO tool ecosystem is the enterprise tier. This roundup is geared toward SEO for small to midsize businesses (SMBs), for which these platforms are likely priced out of reach. But there's a handful of enterprise SEO software providers out there that essentially roll all of the self-service tools into one comprehensive platform. These platforms combine ongoing position monitoring, deep keyword research, and crawling with customizable reports andanalytics.
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.
Congrats Floyd! To answer your question: a big part of the success depends on how much your content replaces the old content… or is a good fit for that page in general. In the example I gave, my CRO guide wasn’t 1:1 replacement for the dead link. But it did make sense for people to add it to their pages because they tended to be “list of CRO resources” type things. Hope that helps.

When it comes to finally choosing the SEO tools that suit your organization's needs, the decision comes back to that concept of gaining tangible ground. It's about discerning which tools provide the most effective combination of keyword-driven SEO investigation capabilities, and then on top of that, the added keyword organization, analysis, recommendations, and other useful functionality to take action on the SEO insights you uncover. If a product is telling you what optimizations need to be made to your website, does it then provide technology to help you make those improvements?
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:
The third type of crawling tool that we touched upon during testing is backlink tracking. Backlinks are one of the building blocks of good SEO. Analyzing the quality of your website's inbound backlinks and how they're feeding into your domain architecture can give your SEO team insight into everything from your website's strongest and weakest pages to search visibility on particular keywords against competing brands.

The terms SEO experts often start with are page authority (PA) and domain authority (DA). DA, a concept in fact coined by Moz, is a 100-point scale that predicts how well a website will rank on search engines. PA is the modern umbrella term for what started as Google's original PageRank algorithm, developed by co-founders Larry Page and Sergey Brin. Google still uses PageRank internally but has gradually stopped supporting the increasingly irrelevant metric, which it now rarely updates. PA is the custom metric each SEO vendor now calculates independently to gauge and rate (again, on a scale of 100) the link structure and authoritative strength of an individual page on any given domain. There is an SEO industry debate as to the validity of PA and DA, and how much influence the PageRank algorithm still holds in Google results (more on that in a bit), but outside of Google's own analytics, they're the most widely accepted metrics out there.


Another example when the “nofollow" attribute can come handy are widget links. If you are using a third party's widget to enrich the experience of your site and engage users, check if it contains any links that you did not intend to place on your site along with the widget. Some widgets may add links to your site which are not your editorial choice and contain anchor text that you as a webmaster may not control. If removing such unwanted links from the widget is not possible, you can always disable them with “nofollow" attribute. If you create a widget for functionality or content that you provide, make sure to include the nofollow on links in the default code snippet.
If you are using Responsive Web Design, use meta name="viewport" tag to tell the browser how to adjust the content. If you use Dynamic Serving, use the Vary HTTP header to signal your changes depending on the user-agent. If you are using separate URLs, signal the relationship between two URLs by tag with rel="canonical" and rel="alternate" elements.
On the voice and natural language side, it's all about FAQs (frequently asked questions). Virtual assistants and smart home devices have made voice recognition and natural language processing (NLP) not only desirable but an expected search vector. To predict how to surface a business's results in a voice search, SEO professionals now need to concentrate on ranking for the common NL queries around target keywords. Google's Quick Answers exist to give its traditional text-based search results an easy NL component to pull from when Google Assistant is answering questions.
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]
If Google finds two identical pieces of content, whether on your own site, or on another you’re not even aware of, it will only index one of those pages. You should be aware of scraper sites, stealing your content automatically and republishing as your own. Here’s Graham Charlton’s thorough investigation on what to if your content ends up working better for somebody else.

We expect advertisements to be visible. However, you should not let the advertisements distract users or prevent them from consuming the site content. For example, advertisements, supplement contents, or interstitial pages (pages displayed before or after the content you are expecting) that make it difficult to use the website.

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.
I’m really grateful for your generous post, Brian. I’m definitely going to implement TOC on some of my over 4k words posts, where I’m trying to become the source. 😉 And I will also use the stats on some new posts. Thanks to you, I also researched big keywords, which I’d stayed away from, and found that many of the high CPC and ranking articles are from 2014. Hoping some of my fresh new content helps rank me higher. Love what you do, sir!

Maintenance. Ongoing addition and modification of keywords and website con­tent are necessary to continually improve search engine rankings so growth doesn’t stall or decline from neglect. You also want to review your link strategy and ensure that your inbound and outbound links are relevant to your business. A blog can provide you the necessary structure and ease of content addition that you need. Your hosting company can typically help you with the setup/installation of a blog.

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.
Hey Sharon, great post! Re. dwell time – I’ve read conflicting opinions, some saying that Google DOES consider it an ‘important’ ranking signal, and others saying that it doesn’t, because dwell time can sometimes be a misleading indicator of content quality. For example when a user searches for something specific and finds the answer immediately in the recommended page (meaning that the content on the page is actually spot on) so he returns to the SERPs very quickly. I have been unable to locate any definitive statements (written/spoken) from anyone at Google that suggest that dwell time IS still a factor in ranking considerations, but it makes sense (to me, anyway) that it should be. Do you have any ‘proof’ one way or the other re. whether Google definitely considers dwell time or not?
