Inclusion in Google's search results is free and easy; you don't even need to submit your site to Google. Google is a fully automated search engine that uses web crawlers to explore the web constantly, looking for sites to add to our index. In fact, the vast majority of sites listed in our results aren't manually submitted for inclusion, but found and added automatically when we crawl the web. Learn how Google discovers, crawls, and serves web pages.3

When would this be useful? If your site has a blog with public commenting turned on, links within those comments could pass your reputation to pages that you may not be comfortable vouching for. Blog comment areas on pages are highly susceptible to comment spam. Nofollowing these user-added links ensures that you're not giving your page's hard-earned reputation to a spammy site.

The caveat in all of this is that, in one way or another, most of the data and the rules governing what ranks and what doesn't (often on a week-to-week basis) comes from Google. If you know where to find and how to use the free and freemium tools Google provides under the surface—AdWords, Google Analytics, and Google Search Console being the big three—you can do all of this manually. Much of the data that the ongoing position monitoring, keyword research, and crawler tools provide is extracted in one form or another from Google itself. Doing it yourself is a disjointed, meticulous process, but you can piece together all the SEO data you need to come up with an optimization strategy should you be so inclined.


Do you regularly publish helpful, useful articles, videos or other types of media that are popular and well produced? Do you write for actual human beings rather than the search engine itself? Well, you should. Latest research from Searchmetrics on ranking factors indicates that Google is moving further towards longer-form content that understands a visitor’s intention as a whole, instead of using keywords based on popular search queries to create content.
There are three types of crawling, all of which provide useful data. Internet-wide crawlers are for large-scale link indexing. It's a complicated and often expensive process but, as with social listening, the goal is for SEO experts, business analysts, and entrepreneurs to be able to map how websites link to one another and extrapolate larger SEO trends and growth opportunities. Crawling tools generally do this with automated bots continuously scanning the web. As is the case with most of these SEO tools, many businesses use internal reporting features in tandem with integrated business intelligence (BI) tools to identify even deeper data insights. Ahrefs and Majestic are the two clear leaders in this type of crawling. They have invested more than a decade's worth of time and resources, compiling and indexing millions and billions, respectively, of crawled domains and pages.
AWR Cloud, our third Editors' Choice, is rated slightly lower than Moz Pro and SpyFu as an all-in-one SEO platform. However, AWR Cloud leads the pack in ongoing position monitoring and proactive search rank tracking on top of solid overall functionality. On the ad hoc keyword research front, the KWFinder.com tool excels. DeepCrawl's laser focus on comprehensive domain scanning is unmatched for site crawling, while Ahrefs and Majetic can duke it out for the best internet-wide crawling index. When it comes to backlinks tracking, LinkResearchTools and Majestic are the top choices. SEMrush and Searchmetrics do a bit of everything.
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.
Early versions of search algorithms relied on webmaster-provided information such as the keyword meta tag or index files in engines like ALIWEB. Meta tags provide a guide to each page's content. Using metadata to index pages was found to be less than reliable, however, because the webmaster's choice of keywords in the meta tag could potentially be an inaccurate representation of the site's actual content. Inaccurate, incomplete, and inconsistent data in meta tags could and did cause pages to rank for irrelevant searches.[10][dubious – discuss] Web content providers also manipulated some attributes within the HTML source of a page in an attempt to rank well in search engines.[11] By 1997, search engine designers recognized that webmasters were making efforts to rank well in their search engine, and that some webmasters were even manipulating their rankings in search results by stuffing pages with excessive or irrelevant keywords. Early search engines, such as Altavista and Infoseek, adjusted their algorithms to prevent webmasters from manipulating rankings.[12]
Ever heard of Maslow's hierarchy of needs? It's a theory of psychology that prioritizes the most fundamental human needs (like air, water, and physical safety) over more advanced needs (like esteem and social belonging). The theory is that you can't achieve the needs at the top without ensuring the more fundamental needs are met first. Love doesn't matter if you don't have food.
The emphasis on tools, meaning plural, is important because there's no one magical way to plop your website atop every single search results page, at least not organically, though there are best practices to do so. If you want to buy a paid search ad spot, then Google AdWords will happily take your money. This will certainly put your website at the top of Google's search results but always with an indicator that yours is a paid position. To win the more valuable and customer-trusted organic search spots (meaning those spots that start below all of those marked with an "Ad" icon), you must have a balanced and comprehensive SEO strategy in place.

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.
Keyword analysis. From nomination, further identify a targeted list of key­words and phrases. Review competitive lists and other pertinent industry sources. Use your preliminary list to determine an indicative number of recent search engine queries and how many websites are competing for each key­word. Prioritize keywords and phrases, plurals, singulars and misspellings. (If search users commonly misspell a keyword, you should identify and use it). Please note that Google will try to correct the term when searching, so use this with care.

For traditional SEO, this has meant some loss of key real estate. For SERP results pages that once had 10 positions, it's not uncommon now to see seven organic search results below a Featured Snippet or Quick Answer box. Rather than relying on PageRank algorithm for a specific keyword, Google search queries rely increasingly on ML algorithms and the Google Knowledge Graph to trigger a Quick Answer or pull a description into a snippet atop the SERP.


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.
If you want to develop a real-time multitasking plagiarism detection system, incorporated into your website, then we have your back. The Plagiarism Checker API offers you a great API integration solution. This completely eliminates the need to check each and every article for every student individually and saves you hours upon hours of work and headache. You can check plagiarism for multiple essays, thesis or assignments of your students in just one click. This also works great for big websites who accept dozens of articles from contributors frequently.

Description meta tags are important because Google might use them as snippets for your pages. Note that we say "might" because Google may choose to use a relevant section of your page's visible text if it does a good job of matching up with a user's query. Adding description meta tags to each of your pages is always a good practice in case Google cannot find a good selection of text to use in the snippet. The Webmaster Central Blog has informative posts on improving snippets with better description meta tags18 and better snippets for your users19. We also have a handy Help Center article on how to create good titles and snippets20.
By relying so much on factors such as keyword density which were exclusively within a webmaster's control, early search engines suffered from abuse and ranking manipulation. To provide better results to their users, search engines had to adapt to ensure their results pages showed the most relevant search results, rather than unrelated pages stuffed with numerous keywords by unscrupulous webmasters. This meant moving away from heavy reliance on term density to a more holistic process for scoring semantic signals.[13] Since the success and popularity of a search engine is determined by its ability to produce the most relevant results to any given search, poor quality or irrelevant search results could lead users to find other search sources. Search engines responded by developing more complex ranking algorithms, taking into account additional factors that were more difficult for webmasters to manipulate. In 2005, an annual conference, AIRWeb (Adversarial Information Retrieval on the Web), was created to bring together practitioners and researchers concerned with search engine optimization and related topics.[14]

This review roundup covers 10 SEO tools: Ahrefs, AWR Cloud, DeepCrawl, KWFinder.com, LinkResearchTools, Majestic, Moz Pro, Searchmetrics Essentials, SEMrush, and SpyFu. The primary function of KWFinder.com, Moz Pro, SEMrush, and SpyFu falls under keyword-focused SEO. When deciding what search topics to target and how best to focus your SEO efforts, treating keyword querying like an investigative tool is where you'll likely get the best results.
Difficulty scores are the SEO market's answer to the patchwork state of all the data out there. All five tools we tested stood out because they do offer some version of a difficulty metric, or one holistic 1-100 score of how difficult it would be for your page to rank organically (without paying Google) on a particular keyword. Difficulty scores are inherently subjective, and each tool calculates it uniquely. In general, it incorporates PA, DA, and other factors, including search volume on the keyword, how heavily paid search ads are influencing the results, and how the strong the competition is in each spot on the current search results page.

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.
Creating high quality content takes a significant amount of at least one of the following: time, effort, expertise, and talent/skill. Content should be factually accurate, clearly written, and comprehensive. So, for example, if you describe your page as a recipe, provide a complete recipe that is easy to follow, rather than just a set of ingredients or a basic description of the dish.
Crawlers are largely a separate product category. There is some overlap with the self-service keyword tools (Ahrefs, for instance, does both), but crawling is another important piece of the puzzle. We tested several tools with these capabilities either as their express purpose or as features within a larger platform. Ahrefs, DeepCrawl, Majestic, and LinkResearchTools are all primarily focused on crawling and backlink tracking, the inbound links coming to your site from another website. Moz Pro, SpyFu, SEMrush, and AWR Cloud all include domain crawling or backlink tracking features as part of their SEO arsenals.
You can confer some of your site's reputation to another site when your site links to it. Sometimes users can take advantage of this by adding links to their own site in your comment sections or message boards. Or sometimes you might mention a site in a negative way and don't want to confer any of your reputation upon it. For example, imagine that you're writing a blog post on the topic of comment spamming and you want to call out a site that recently comment spammed your blog. You want to warn others of the site, so you include the link to it in your content; however, you certainly don't want to give the site some of your reputation from your link. This would be a good time to use nofollow.
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.
Ultimately, we awarded Editors' Choices to three tools: Moz Pro, SpyFu, and AWR Cloud. Moz Pro is the best overall SEO platform of the bunch, with comprehensive tooling across keyword research, position monitoring, and crawling on top of industry-leading metrics incorporated by many of the other tools in this roundup. SpyFu is the tool with the best user experience (UX) for non-SEO experts and the deepest array of ROI metrics as well as SEO lead management for an integrated digital sales and marketing team.

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.
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.

All of this plays into a new way businesses and SEO professionals need to think when approaching what keywords to target and what SERP positions to chase. The enterprise SEO platforms are beginning to do this, but the next step in SEO is full-blown content recommendation engines and predictive analytics. By using all of the data you pull from your various SEO tools, Google Search Console, and keyword and trend data from social listening platforms, you can optimize for a given keyword or query before Google does it first. If your keyword research uncovers a high-value keyword or SERP for which Google has not yet monetized the page with a Quick Answer or a Featured Snippet, then pounce on that opportunity.
