Smartphone - In this document, "mobile" or “mobile devices" refers to smartphones, such as devices running Android, iPhone, or Windows Phone. Mobile browsers are similar to desktop browsers in that they can render a broad set of the HTML5 specification, although their screen size is smaller and in almost all cases their default orientation is vertical.

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]
When using the Keyword Explorer, Ahrefs will also produce the "parent topic" of the keyword you looked up, as you can see in the screenshot above, underneath the Keyword Difficulty meter. A keyword's parent topic is a broader keyword with higher search volume than your intended keyword, but likely has the same audience and ranking potential -- giving you more a valuable SEO opportunity when optimizing a particular blog post or webpage.
Search engine optimization (SEO) is often about making small modifications to parts of your website. When viewed individually, these changes might seem like incremental improvements, but when combined with other optimizations, they could have a noticeable impact on your site's user experience and performance in organic search results. You're likely already familiar with many of the topics in this guide, because they're essential ingredients for any web page, but you may not be making the most out of them.
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.

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?
Users will occasionally come to a page that doesn't exist on your site, either by following a broken link or typing in the wrong URL. Having a custom 404 page30 that kindly guides users back to a working page on your site can greatly improve a user's experience. Your 404 page should probably have a link back to your root page and could also provide links to popular or related content on your site. You can use Google Search Console to find the sources of URLs causing "not found" errors31.
SEO stands for ‘Search Engine Optimization’. It’s the practice of optimizing your web pages to make them reach a high position in the search results of Google or other search engines. SEO focuses on improving the rankings in the organic – aka non paid – search results. If you have a website and you want to get more traffic, it should be part of your marketing efforts. Here, I’ll explain what SEO is and how we approach it at Yoast.
When it comes down to it, you want to choose a platform or invest in complementary tools that provide a single unified SEO workflow. It begins with keyword research to target optimal keywords and SERP positions for your business, along with SEO recommendations to help your rank. Those recommendations feed naturally into crawing tools, which should give you insight into your website and competitors' sites to then optimize for those targeted opportunities. Once you're ranking on those keywords, vigilant monitoring and rank tracking should help maintain your positions and grow your lead on competitors when it comes to the search positions that matter to your organization's bottom line. Finally, the best tools also tie those key search positions directly to ROI with easy-to-understand metrics, and feed your SEO deliverables and goals right back into your digital marketing strategy.
In 2007, Google announced a campaign against paid links that transfer PageRank.[30] On June 15, 2009, Google disclosed that they had taken measures to mitigate the effects of PageRank sculpting by use of the nofollow attribute on links. Matt Cutts, a well-known software engineer at Google, announced that Google Bot would no longer treat any nofollow links, in the same way, to prevent SEO service providers from using nofollow for PageRank sculpting.[31] As a result of this change the usage of nofollow led to evaporation of PageRank. In order to avoid the above, SEO engineers developed alternative techniques that replace nofollowed tags with obfuscated JavaScript and thus permit PageRank sculpting. Additionally several solutions have been suggested that include the usage of iframes, Flash and JavaScript.[32]
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.
Website-specific crawlers, or software that crawls one particular website at a time, are great for analyzing your own website's SEO strengths and weaknesses; they're arguably even more useful for scoping out the competition's. Website crawlers analyze a website's URL, link structure, images, CSS scripting, associated apps, and third-party services to evaluate SEO. Not unlike how a website monitoring tool scans for a webpage's overall "health," website crawlers can identify factors such as broken links and errors, website lag, and content or metadata with low keyword density and SEO value, while mapping a website's architecture. Website crawlers can help your business improve website user experience (UX) while identifying key areas of improvement to help pages rank better. DeepCrawl is, by far, the most granular and detailed website crawler in this roundup, although Ahrefs and Majestic also provide comprehensive domain crawling and website optimization recommendations. Another major crawler we didn't test is Screaming Frog, which we'll soon discuss in the section called "The Enterprise Tier."
SEO techniques can be classified into two broad categories: techniques that search engine companies recommend as part of good design ("white hat"), and those techniques of which search engines do not approve ("black hat"). The search engines attempt to minimize the effect of the latter, among them spamdexing. Industry commentators have classified these methods, and the practitioners who employ them, as either white hat SEO, or black hat SEO.[50] White hats tend to produce results that last a long time, whereas black hats anticipate that their sites may eventually be banned either temporarily or permanently once the search engines discover what they are doing.[51]
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.
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.
