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.


In some contexts, the term SEM is used exclusively to mean pay per click advertising,[2] particularly in the commercial advertising and marketing communities which have a vested interest in this narrow definition. Such usage excludes the wider search marketing community that is engaged in other forms of SEM such as search engine optimization and search retargeting.
In addition to giving you insight into the search volume and competition level of keywords, most keyword research tools will also give you detailed information about the average or current estimated CPC for particular keywords are. This is particularly important for businesses with smaller ad budgets and this feature allows you to predict whether certain keywords will be truly beneficial to your ad campaigns or if they’ll cost too much.
SEM is the wider discipline that incorporates SEO. SEM includes both paid search results (using tools like Google Adwords or Bing Ads, formerly known as Microsoft adCenter) and organic search results (SEO). SEM uses paid advertising with AdWords or Bing Ads, pay per click (particularly beneficial for local providers as it enables potential consumers to contact a company directly with one click), article submissions, advertising and making sure SEO has been done. A keyword analysis is performed for both SEO and SEM, but not necessarily at the same time. SEM and SEO both need to be monitored and updated frequently to reflect evolving best practices.
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]

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.
Instagram has proven itself a powerful platform for marketers to reach their customers and prospects through sharing pictures and brief messages. According to a study by Simply Measured, 71% of the world's largest brands are now using Instagram as a marketing channel.[58] For companies, Instagram can be used as a tool to connect and communicate with current and potential customers. The company can present a more personal picture of their brand, and by doing so the company conveys a better and true picture of itself. The idea of Instagram pictures lies on on-the-go, a sense that the event is happening right now, and that adds another layer to the personal and accurate picture of the company. In fact, Thomas Rankin, co-founder and CEO of the program Dash Hudson, stated that when he approves a blogger's Instagram post before it is posted on the behalf of a brand his company represents, his only negative feedback is if it looks too posed. "It's not an editorial photo," he explained, "We're not trying to be a magazine. We're trying to create a moment."[57] Another option Instagram provides the opportunity for companies to reflect a true picture of the brandfrom the perspective of the customers, for instance, using the user-generated contents thought the hashtags encouragement.[59] Other than the filters and hashtags functions, the Instagram's 15-second videos and the recently added ability to send private messages between users have opened new opportunities for brands to connect with customers in a new extent, further promoting effective marketing on Instagram.
Social media itself is a catch-all term for sites that may provide radically different social actions. For instance, Twitter is a social site designed to let people share short messages or “updates” with others. Facebook, in contrast is a full-blown social networking site that allows for sharing updates, photos, joining events and a variety of other activities.

These posts can be one or more of the following: images, photo sets, animated GIFs, video, audio, and text posts. For the users to differentiate the promoted posts to the regular users' posts, the promoted posts have a dollar symbol on the corner. On May 6, 2014, Tumblr announced customization and theming on mobile apps for brands to advertise.[72]
Facebook pages are far more detailed than Twitter accounts. They allow a product to provide videos, photos, longer descriptions, and testimonials where followers can comment on the product pages for others to see. Facebook can link back to the product's Twitter page, as well as send out event reminders. As of May 2015, 93% of businesses marketers use Facebook to promote their brand.[36] A study from 2011 attributed 84% of "engagement" or clicks and likes that link back to Facebook advertising.[37] By 2014, Facebook had restricted the content published from business and brand pages. Adjustments in Facebook algorithms have reduced the audience for non-paying business pages (that have at least 500,000 "Likes") from 16% in 2012 down to 2% in February 2014.[38] [39][40]
Several customers are turning towards social media to express their appreciation or frustration with brands, product or services. Therefore, marketers can measure the frequency of which customers are discussing their brand and judge how effective their SMM strategies are. In recent studies, 72% of people surveyed expressed that they expected a response to their complaints on Twitter within an hour.[111]
Platforms like LinkedIn create an environment for companies and clients to connect online.[65] Companies that recognize the need for information, originality/ and accessibility employ blogs to make their products popular and unique/ and ultimately reach out to consumers who are privy to social media.[66] Studies from 2009 show that consumers view coverage in the media or from bloggers as being more neutral and credible than print advertisements, which are not thought of as free or independent.[67] Blogs allow a product or company to provide longer descriptions of products or services, can include testimonials and can link to and from other social network and blog pages. Blogs can be updated frequently and are promotional techniques for keeping customers, and also for acquiring followers and subscribers who can then be directed to social network pages. Online communities can enable a business to reach the clients of other businesses using the platform. To allow firms to measure their standing in the corporate world, sites enable employees to place evaluations of their companies.[65] Some businesses opt out of integrating social media platforms into their traditional marketing regimen. There are also specific corporate standards that apply when interacting online.[65] To maintain an advantage in a business-consumer relationship, businesses have to be aware of four key assets that consumers maintain: information, involvement, community, and control.[68]
Paid inclusion is a search engine marketing method in itself, but also a tool of search engine optimization, since experts and firms can test out different approaches to improving ranking and see the results often within a couple of days, instead of waiting weeks or months. Knowledge gained this way can be used to optimize other web pages, without paying the search engine company.
As of 2009, there are only a few large markets where Google is not the leading search engine. In most cases, when Google is not leading in a given market, it is lagging behind a local player. The most notable example markets are China, Japan, South Korea, Russia and the Czech Republic where respectively Baidu, Yahoo! Japan, Naver, Yandex and Seznam are market leaders.

Keyword research and analysis involves three "steps": ensuring the site can be indexed in the search engines, finding the most relevant and popular keywords for the site and its products, and using those keywords on the site in a way that will generate and convert traffic. A follow-on effect of keyword analysis and research is the search perception impact.[13] Search perception impact describes the identified impact of a brand's search results on consumer perception, including title and meta tags, site indexing, and keyword focus. As online searching is often the first step for potential consumers/customers, the search perception impact shapes the brand impression for each individual.

Tablet - We consider tablets as devices in their own class, so when we speak of mobile devices, we generally do not include tablets in the definition. Tablets tend to have larger screens, which means that, unless you offer tablet-optimized content, you can assume that users expect to see your site as it would look on a desktop browser rather than on a smartphone browser.

In addition, social media platforms have become extremely aware of their users and collect information about their viewers to connect with them in various ways. Social-networking website Facebook Inc. is quietly working on a new advertising system that would let marketers target users with ads based on the massive amounts of information people reveal on the site about themselves.[104] This may be an unethical or ethical feature to some individuals. Some people may react negatively because they believe it is an invasion of privacy. On the other hand, some individuals may enjoy this feature because their social network recognizes their interests and sends them particular advertisements pertaining to those interests. Consumers like to network with people who have interests and desires that are similar to their own.[105] Individuals who agree to have their social media profile public, should be aware that advertisers have the ability to take information that interests them to be able to send them information and advertisements to boost their sales. Managers invest in social media to foster relationships and interact with customers.[106] This is an ethical way for managers to send messages about their advertisements and products to their consumers.

As an Internet marketing strategy, SEO considers how search engines work, the computer programmed algorithms which 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]
