A breadcrumb is a row of internal links at the top or bottom of the page that allows visitors to quickly navigate back to a previous section or the root page. Many breadcrumbs have the most general page (usually the root page) as the first, leftmost link and list the more specific sections out to the right. We recommend using breadcrumb structured data markup28 when showing breadcrumbs.

The development of digital marketing is inseparable from technology development. One of the key points in the start of was in 1971, where Ray Tomlinson sent the very first email and his technology set the platform to allow people to send and receive files through different machines.[10] However, the more recognisable period as being the start of Digital Marketing is 1990 as this was where the Archie search engine was created as an index for FTP sites. In the 1980s, the storage capacity of computer was already big enough to store huge volumes of customer information. Companies started choosing online techniques, such as database marketing, rather than limited list broker.[11] This kind of databases allowed companies to track customers' information more effectively, thus transforming the relationship between buyer and seller. However, the manual process was not so efficient.


Another ethical controversy associated with search marketing has been the issue of trademark infringement. The debate as to whether third parties should have the right to bid on their competitors' brand names has been underway for years. In 2009 Google changed their policy, which formerly prohibited these tactics, allowing 3rd parties to bid on branded terms as long as their landing page in fact provides information on the trademarked term.[27] Though the policy has been changed this continues to be a source of heated debate.[28]
Let’s say, for example, that you run a construction business that helps with home repairs after natural disasters and you want to advertise that service. The official term for the service is “fire restoration,” but keyword research may indicate that customers in your area search instead for “fire repair” or “repair fire damage to house.” By not optimizing for these two keywords, you’ll lose out on a lot of traffic and potential customers, even if “fire restoration” is technically more correct.
As mobile devices become an increasingly integral part of our lives, it’s vital that marketers understand how to effectively communicate on this unique and extremely personal channel. Mobile devices are kept in our pockets, sit next to our beds, and are checked constantly throughout the day. This makes marketing on mobile incredibly important but also very nuanced.
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.
One of the most enduring misconceptions about search engine marketing is that whomever has the largest advertising budget wins. Although a larger advertising budget can certainly be advantageous, especially when targeting highly competitive keywords, but it’s far from a requirement for success with search engine marketing. This is because all ads go through a process known as the ad auction before appearing alongside search results. For the purposes of this explanation, we’ll be focusing on the ad auction in Google AdWords.
Targeting, viewability, brand safety and invalid traffic: Targeting, viewability, brand safety and invalid traffic all are aspects used by marketers to help advocate digital advertising. Cookies are a form of digital advertising, which are tracking tools within desktop devices; causing difficulty, with shortcomings including deletion by web browsers, the inability to sort between multiple users of a device, inaccurate estimates for unique visitors, overstating reach, understanding frequency, problems with ad servers, which cannot distinguish between when cookies have been deleted and when consumers have not previously been exposed to an ad. Due to the inaccuracies influenced by cookies, demographics in the target market are low and vary (Whiteside, 2016).[44] Another element, which is affected within digital marketing, is ‘viewabilty’ or whether the ad was actually seen by the consumer. Many ads are not seen by a consumer and may never reach the right demographic segment. Brand safety is another issue of whether or not the ad was produced in the context of being unethical or having offensive content. Recognizing fraud when an ad is exposed is another challenge marketers face. This relates to invalid traffic as premium sites are more effective at detecting fraudulent traffic, although non-premium sites are more so the problem (Whiteside, 2016).[44]

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.
Search engine marketing - Search engine marketing (SEM) is a form of Internet marketing that involves the promotion of websites by increasing their visibility in search engine results pages (SERPs) primarily through paid advertising. SEM may incorporate Search engine optimization, which adjusts or rewrites website content and site architecture to achieve a higher ranking in search engine results pages to enhance pay per click (PPC) listings.

Search engine optimization consultants expanded their offerings to help businesses learn about and use the advertising opportunities offered by search engines, and new agencies focusing primarily upon marketing and advertising through search engines emerged. The term "search engine marketing" was popularized by Danny Sullivan in 2001[12] to cover the spectrum of activities involved in performing SEO, managing paid listings at the search engines, submitting sites to directories, and developing online marketing strategies for businesses, organizations, and individuals.
