According to Statistica, 76% of the U.S. population has at least one social networking profile and by 2020 the number of worldwide users of social media is expected to reach 2.95 billion (650 million of these from China alone). Of the social media platforms, Facebook is by far the most dominant - as of the end of the second quarter of 2018 Facebook had approximately 2.23 billion active users worldwide (Statistica). Mobile devices have become the dominant platform for Facebook usage - 68% of time spent on Facebook originates from mobile devices. Other popular social media platforms for marketing include WhatsApp, WeChat, Instagram, Twitter, LinkedIn, Pinterest, and YouTube.

On April 24, 2012 many started to see that Google has started to penalize companies that are buying links for the purpose of passing off the rank. The Google Update was called Penguin. Since then, there have been several different Penguin/Panda updates rolled out by Google. SEM has, however, nothing to do with link buying and focuses on organic SEO and PPC management. As of October 20, 2014 Google has released three official revisions of their Penguin Update.
Let's say, for example, you're researching the keyword "how to start a blog" for an article you want to create. "Blog" can mean a blog post or the blog website itself, and what a searcher's intent is behind that keyword will influence the direction of your article. Does the searcher want to learn how to start an individual blog post? Or do they want to know how to actually launch a website domain for the purposes of blogging? If your content strategy is only targeting people interested in the latter, you'll need to make sure of the keyword's intent before committing to it.
Search engines are expanding – When someone mentions search engines, do you automatically assume they’re talking about Google? The tech giant has such a big share of the market that 'Googling' has become a verb. However, a significant portion of searches takes place on alternative sites, such as Microsoft’s Bing. Make a point to search for your site on Google alternatives to see where you rank. Just improving social media engagement and adding meta tags might be all it takes to boost you a couple ranks on Bing.
Webmasters and content providers began optimizing websites for search engines in the mid-1990s, as the first search engines were cataloging the early Web. Initially, all webmasters only needed to submit the address of a page, or URL, to the various engines which would send a "spider" to "crawl" that page, extract links to other pages from it, and return information found on the page to be indexed.[5] The process involves a search engine spider downloading a page and storing it on the search engine's own server. A second program, known as an indexer, extracts information about the page, such as the words it contains, where they are located, and any weight for specific words, as well as all links the page contains. All of this information is then placed into a scheduler for crawling at a later date.
To avoid undesirable content in the search indexes, webmasters can instruct spiders not to crawl certain files or directories through the standard robots.txt file in the root directory of the domain. Additionally, a page can be explicitly excluded from a search engine's database by using a meta tag specific to robots (usually ). When a search engine visits a site, the robots.txt located in the root directory is the first file crawled. The robots.txt file is then parsed and will instruct the robot as to which pages are not to be crawled. As a search engine crawler may keep a cached copy of this file, it may on occasion crawl pages a webmaster does not wish crawled. Pages typically prevented from being crawled include login specific pages such as shopping carts and user-specific content such as search results from internal searches. In March 2007, Google warned webmasters that they should prevent indexing of internal search results because those pages are considered search spam.[47]
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.[28] Though the policy has been changed this continues to be a source of heated debate.[29]
I want you to do some SERP investigation, meaning perform a search query in Google, see what comes back to you, and then figure out from there what Google believes to be relevant to the keywords searches. What does Google think is the content that will answer this searcher's query? You're trying to figure out intent, the type of content that's required, and whatever missing pieces might be there. If you can find holes where, hey, no one is serving this, but I know that people want the answer to it, you might be able to fill that gap and take over that ranking position. Thanks to Gaetano, @gaetano_nyc, for the great suggestion on this one.
The searcher has a high probability of being in a certain area: For instance, “Why did Oklahoma Joe’s change their name?” could be considered a local term because there’s a good chance the searcher is from Kansas or Missouri. Why? Those are the only two states where this exceptional barbecue establishment calls home. By the way, it is now called Joe’s Kansas City BBQ if you ever happen to be coming through town.

Now, some buckets are worth more than others, and the three main buckets that you need to be aware of for search rankings are quality, trust and authority. So quality: what Google is trying to measure when they’re trying to figure out what sites should rank is offering something valuable or unique or interesting to googles searchers. For example: good content—if you are selling t-shirts and you are using the same description that every other t-shirt seller is using on their website then you are not offering anything unique to Google’s searchers.
This is not possible for everyone. But in some cases, in the case that you're getting into Google news, or in the case that you're in the recipe world and you can get visuals and images, or in the case where you have a featured snippet opportunity and you can get the visual for that featured snippet along with that credit, or in the case where you can get rich snippets around travel or around flights, other verticals that schema is supporting right now, well, that's great. You should take advantage of those opportunities.

How much of your marketing strategy should be done online and which internet marketing elements you use depends on the nature of your business, your budget, your time, and your goals. Many small business owners do it all themselves in the beginning, but as their businesses grow, they begin to pay for services or outsource work to a virtual assistant that can help them with online marketing.

The key distinction is that SEM is a broader strategy which combines paid search and SEO tactics. So, if you set up a PPC advertisement, but don't take steps to optimize the ad or the website it links to, this is a standard example of paid search. However, if you optimize your site and your search content with solid keywords, then you put money behind it to boost it on targeted audience's search pages, then you're dabbling in SEM.
