Optimizing a website may involve editing its content, adding content, and modifying HTML and associated coding to both increase its relevance to specific keywords and remove barriers to the indexing activities of search engines like Google ,Yahoo etc.[citation needed] Promoting a site to increase the number of backlinks, or inbound links, is another SEO tactic. By May 2015, mobile search had surpassed desktop search.[3]
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.
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?

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]
After the Panda update rolled out, the latent risk in such a strategy could (typically would) vastly exceed the direct cost of the content, as poor pages on one part of a site could drag down the ranking of other pages on the site which targeted different keywords. Some sites have seen their search traffic fall over 90% with their ad revenues falling even faster. Demand Media went from being worth a couple billion to tens of millions of Dollars. ArticlesBase.com sold on Flippa for $80,000, but was making over $500,000 PER MONTH in profit before getting hit by Panda. Many other Panda-torched sites like Suite101 have simply went offline.
Robots.txt is not an appropriate or effective way of blocking sensitive or confidential material. It only instructs well-behaved crawlers that the pages are not for them, but it does not prevent your server from delivering those pages to a browser that requests them. One reason is that search engines could still reference the URLs you block (showing just the URL, no title or snippet) if there happen to be links to those URLs somewhere on the Internet (like referrer logs). Also, non-compliant or rogue search engines that don't acknowledge the Robots Exclusion Standard could disobey the instructions of your robots.txt. Finally, a curious user could examine the directories or subdirectories in your robots.txt file and guess the URL of the content that you don't want seen.

Where the free Google tools can provide complementary value is in fact-checking. If you're checking out more than one of these SEO tools, you'll quickly realize this isn't an exact science. If you were to look at the PA, DA, and keyword difficulty scores across KWFinder.com, Moz, SpyFu, SEMrush, Ahrefs, AWR Cloud, and Searchmetrics for the same set of keywords, you might get different numbers across each metric separated by anywhere from a few points to dozens. If your business is unsure about an optimization campaign on a particular keyword, you can cross-check with data straight from a free AdWords account and Search Console. Another trick: Enable Incognito mode in your browser along with an extension like the free Moz Toolbar and you can run case-by-case searches on specific keywords to get an organic look at your target search results page.
Searching Google.com in an incognito window will bring up that all-familiar list of autofill options, many of which can help guide your keyword research. The incognito ensures that any customized search data Google stores when you’re signed in gets left out. Incognito may also be helpful to see where you truly rank on a results page for a certain term.
While most of the links to your site will be added gradually, as people discover your content through search or other ways and link to it, Google understands that you'd like to let others know about the hard work you've put into your content. Effectively promoting your new content will lead to faster discovery by those who are interested in the same subject. As with most points covered in this document, taking these recommendations to an extreme could actually harm the reputation of your site.
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.

That's why PA and DA metrics often vary from tool to tool. Each ad hoc keyword tool we tested came up with slightly different numbers based on what they're pulling from Google and other sources, and how they're doing the calculating. The shortcoming of PA and DA is that, even though they give you a sense of how authoritative a page might be in the eyes of Google, they don't tell you how easy or difficult it will be to position it for a particular keyword. This difficulty is why a third, newer metric is beginning to emerge among the self-service SEO players: difficulty scores.
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.
For example, within the HubSpot Blogging App, users will find as-you-type SEO suggestions. This helpful inclusion serves as a checklist for content creators of all skill levels. HubSpot customers also have access to the Page Performance App, Sources Report, and the Keyword App. The HubSpot Marketing Platform will provide you with the tools you need to research keywords, monitor their performance, track organic search growth, and diagnose pages that may not be fully optimized.

A navigational page is a simple page on your site that displays the structure of your website, and usually consists of a hierarchical listing of the pages on your site. Visitors may visit this page if they are having problems finding pages on your site. While search engines will also visit this page, getting good crawl coverage of the pages on your site, it's mainly aimed at human visitors.
Link text is the visible text inside a link. This text tells users and Google something about the page you're linking to. Links on your page may be internal—pointing to other pages on your site—or external—leading to content on other sites. In either of these cases, the better your anchor text is, the easier it is for users to navigate and for Google to understand what the page you're linking to is about.

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.
As an Internet marketing strategy, SEO considers how search engines work, the computer-programmed algorithms that dictate search engine behavior, what people search for, the actual search terms or keywords typed into search engines, and which search engines are preferred by their targeted audience. SEO is performed because a website will receive more visitors from a search engine the higher the website ranks in the search engine results page (SERP). These visitors can then be converted into customers.[4]
