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.
You should build a website to benefit your users, and any optimization should be geared toward making the user experience better. One of those users is a search engine, which helps other users discover your content. Search Engine Optimization is about helping search engines understand and present content. Your site may be smaller or larger than our example site and offer vastly different content, but the optimization topics we discuss below should apply to sites of all sizes and types. We hope our guide gives you some fresh ideas on how to improve your website, and we'd love to hear your questions, feedback, and success stories in the Google Webmaster Help Forum1.
When your business has an idea about a new search topic for which you think your content has the potential to rank highly, the ability to spin up a query and investigate it right away is key. Even more importantly, the tool should give you enough data points, guidance, and recommendations to confirm whether or not that particular keyword, or a related keyword or search phrase, is an SEO battle worth fighting (and, if so, how to win). We'll get into the factors and metrics to help you make those decisions a little later.
This can be broken down into three primary categories: ad hoc keyword research, ongoing search position monitoring, and crawling, which is when Google bots search through sites to determine which pages to index. In this roundup, we'll explain what each of those categories means for your business, the types of platforms and tools you can use to cover all of your SEO bases, and what to look for when investing in those tools.

This is a rather crude metric because it presumes one can monetize all the traffic they receive AND one can generate as much profit per visitor as Google does. Anyone who could do both of those would likely displace Google as the first consumer destination in their market (like how many people in the United States start ecommerce searches on rather than

"Organic search" pertains to how vistors arrive at a website from running a search query (most notably Google, who has 90 percent of the search market according to StatCounter. Whatever your products or services are, appearing as close to the top of search results for your specific business has become a critical objective for most businesses. Google continously refines, and to the chagrin of search engine optimization (SEO) managers, revises its search algorithms. They employ new techniques and technologies including artificial intelligence (AI) to weed out low value, poorly created pages. This brings about monumental challenges in maintaining an effective SEO strategy and good search results. We've looked at the best tools to ket you optimize your website's placement within search rankings.
When referring to the homepage, a trailing slash after the hostname is optional since it leads to the same content ("" is the same as ""). For the path and filename, a trailing slash would be seen as a different URL (signaling either a file or a directory), for example, "" is not the same as "".
It has an option for automatically rewriting the content you run on it in just one click. If your content contains plagiarized work, all you have to do is click on the rewrite option and you'll be taken to our auto-paraphrasing tool, where your content will be updated immediately. This is a built-in feature available right inside the tool for absolutely free.

On October 17, 2002, SearchKing filed suit in the United States District Court, Western District of Oklahoma, against the search engine Google. SearchKing's claim was that Google's tactics to prevent spamdexing constituted a tortious interference with contractual relations. On May 27, 2003, the court granted Google's motion to dismiss the complaint because SearchKing "failed to state a claim upon which relief may be granted."[68][69]

By 2004, search engines had incorporated a wide range of undisclosed factors in their ranking algorithms to reduce the impact of link manipulation. In June 2007, The New York Times' Saul Hansell stated Google ranks sites using more than 200 different signals.[26] The leading search engines, Google, Bing, and Yahoo, do not disclose the algorithms they use to rank pages. Some SEO practitioners have studied different approaches to search engine optimization, and have shared their personal opinions.[27] Patents related to search engines can provide information to better understand search engines.[28] In 2005, Google began personalizing search results for each user. Depending on their history of previous searches, Google crafted results for logged in users.[29]
LinkResearchTools makes backlink tracking its core mission and provides a wide swath of backlink analysis tools. LinkResearchTools and Majestic provide the best backlink crawling of this bunch. Aside from these two backlink powerhouses, many of the other tools we tested, such as Ahrefs, Moz Pro, Searchmetrics, SEMrush, and SpyFu, also include solid backlink tracking capabilities.
This broken-link checker makes it easy for a publisher or editor to make corrections before a page is live. Think about a site like Wikipedia, for example. The Wikipedia page for the term "marketing" contains a whopping 711 links. Not only was Check My Links able to detect this number in a matter of seconds, but it also found (and highlighted) seven broken links.
If you own, manage, monetize, or promote online content via Google Search, this guide is meant for you. You might be the owner of a growing and thriving business, the webmaster of a dozen sites, the SEO specialist in a Web agency or a DIY SEO ninja passionate about the mechanics of Search : this guide is meant for you. If you're interested in having a complete overview of the basics of SEO according to our best practices, you are indeed in the right place. This guide won't provide any secrets that'll automatically rank your site first in Google (sorry!), but following the best practices outlined below will hopefully make it easier for search engines to crawl, index and understand your content.
In February 2011, Google announced the Panda update, which penalizes websites containing content duplicated from other websites and sources. Historically websites have copied content from one another and benefited in search engine rankings by engaging in this practice. However, Google implemented a new system which punishes sites whose content is not unique.[36] The 2012 Google Penguin attempted to penalize websites that used manipulative techniques to improve their rankings on the search engine.[37] Although Google Penguin has been presented as an algorithm aimed at fighting web spam, it really focuses on spammy links[38] by gauging the quality of the sites the links are coming from. The 2013 Google Hummingbird update featured an algorithm change designed to improve Google's natural language processing and semantic understanding of web pages. Hummingbird's language processing system falls under the newly recognized term of 'Conversational Search' where the system pays more attention to each word in the query in order to better match the pages to the meaning of the query rather than a few words [39]. With regards to the changes made to search engine optimization, for content publishers and writers, Hummingbird is intended to resolve issues by getting rid of irrelevant content and spam, allowing Google to produce high-quality content and rely on them to be 'trusted' authors.
Search engines use complex mathematical algorithms to interpret which websites a user seeks. In this diagram, if each bubble represents a website, programs sometimes called spiders examine which sites link to which other sites, with arrows representing these links. Websites getting more inbound links, or stronger links, are presumed to be more important and what the user is searching for. In this example, since website B is the recipient of numerous inbound links, it ranks more highly in a web search. And the links "carry through", such that website C, even though it only has one inbound link, has an inbound link from a highly popular site (B) while site E does not. Note: Percentages are rounded.
All sites have a home or "root" page, which is usually the most frequented page on the site and the starting place of navigation for many visitors. Unless your site has only a handful of pages, you should think about how visitors will go from a general page (your root page) to a page containing more specific content. Do you have enough pages around a specific topic area that it would make sense to create a page describing these related pages (for example, root page -> related topic listing -> specific topic)? Do you have hundreds of different products that need to be classified under multiple category and subcategory pages?
Since heading tags typically make text contained in them larger than normal text on the page, this is a visual cue to users that this text is important and could help them understand something about the type of content underneath the heading text. Multiple heading sizes used in order create a hierarchical structure for your content, making it easier for users to navigate through your document.

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.
