Google uses a hyperlink based algorithm (known as ‘PageRank’) to calculate the popularity and authority of a page, and while Google is far more sophisticated today, this is still a fundamental signal in ranking. SEO can therefore also include activity to help improve the number and quality of ‘inbound links’ to a website, from other websites. This activity has historically been known as ‘link building’, but is really just marketing a brand with an emphasis online, through content or digital PR for example.
Digital marketing activity is still growing across the world according to the headline global marketing index. A study published in September 2018, found that global outlays on digital marketing tactics are approaching $100 billion. Digital media continues to rapidly grow; while the marketing budgets are expanding, traditional media is declining (World Economics, 2015). Digital media helps brands reach consumers to engage with their product or service in a personalised way. Five areas, which are outlined as current industry practices that are often ineffective are prioritizing clicks, balancing search and display, understanding mobiles, targeting, viewability, brand safety and invalid traffic, and cross-platform measurement (Whiteside, 2016). Why these practices are ineffective and some ways around making these aspects effective are discussed surrounding the following points.
Cross-platform measurement: The number of marketing channels continues to expand, as measurement practices are growing in complexity. A cross-platform view must be used to unify audience measurement and media planning. Market researchers need to understand how the Omni-channel affects consumer's behaviour, although when advertisements are on a consumer's device this does not get measured. Significant aspects to cross-platform measurement involves de-duplication and understanding that you have reached an incremental level with another platform, rather than delivering more impressions against people that have previously been reached (Whiteside, 2016). An example is ‘ESPN and comScore partnered on Project Blueprint discovering the sports broadcaster achieved a 21% increase in unduplicated daily reach thanks to digital advertising’ (Whiteside, 2016). Television and radio industries are the electronic media, which competes with digital and other technological advertising. Yet television advertising is not directly competing with online digital advertising due to being able to cross platform with digital technology. Radio also gains power through cross platforms, in online streaming content. Television and radio continue to persuade and affect the audience, across multiple platforms (Fill, Hughes, & De Franceso, 2013).
While Google never sells better ranking in our search results, several other search engines combine pay-per-click or pay-for-inclusion results with their regular web search results. Some SEOs will promise to rank you highly in search engines, but place you in the advertising section rather than in the search results. A few SEOs will even change their bid prices in real time to create the illusion that they "control" other search engines and can place themselves in the slot of their choice. This scam doesn't work with Google because our advertising is clearly labeled and separated from our search results, but be sure to ask any SEO you're considering which fees go toward permanent inclusion and which apply toward temporary advertising.
In the page, the text “Post Modern Marketing” is a link that points to the homepage of our website, www.postmm.com. That link is an outgoing link for Forbes, but for our website it is an incoming link, or backlink. Usually, the links are styled differently than the rest of the page text, for easy identification. Often they'll be a different color, underlined, or accompany an icon - all these indicate that if you click, you can visit the page the text is referencing.
A backlink is a reference comparable to a citation. The quantity, quality, and relevance of backlinks for a web page are among the factors that search engines like Google evaluate in order to estimate how important the page is. PageRank calculates the score for each web page based on how all the web pages are connected among themselves, and is one of the variables that Google Search uses to determine how high a web page should go in search results. This weighting of backlinks is analogous to citation analysis of books, scholarly papers, and academic journals. A Topical PageRank has been researched and implemented as well, which gives more weight to backlinks coming from the page of a same topic as a target page. 
But I'm not talking about any kind of link building. I'm talking about organic link building by getting out there and creating insatiable "anchor content" on your website, then linking to that content with equally-great content that's created on authority sites like Medium, Quora, LinkedIn and other publishing platforms. It's not easy by any measure. Google is far more wary of newcomers these days than it once used to be.
If your website is filled with videos, but you’re simply not ranking for them, there may be an issue with Google’s ability to evaluate the video content on your site. Solve that problem by creating a video sitemap. Google enabled sitemap protocol for video content in 2007. Creating a video sitemap will tell Google precisely where all of your videos are located and what the content is in each video.
Ask for a technical and search audit for your site to learn what they think needs to be done, why, and what the expected outcome should be. You'll probably have to pay for this. You will probably have to give them read-only access to your site on Search Console. (At this stage, don't grant them write access.) Your prospective SEO should be able to give you realistic estimates of improvement, and an estimate of the work involved. If they guarantee you that their changes will give you first place in search results, find someone else.
I segmented different verticals, did a Google search to see which website ranked #1 for that query (keep in mind that I performed this search using a VPN and not at the targeted location to get 'cleaner' results, so yours would be different, especially for local types of businesses), added it to my list, and then averaged out the percentages of link types (which I pulled from ahrefs.com). Click the link below to see my dataset.
There are ten essential types of marketing that can be done online. Some of these can be broken down into organic marketing and others can be categorized as paid marketing. Organic, of course, is the allure of marketing professionals from around the planet. It's free and its unencumbered traffic that simply keeps coming. Paid marketing, on the other hand, is still a very attractive proposition as long as the marketing pays for itself by having the right type of offer that converts.
The world is mobile today. Most people are searching on Google using a mobile device. The desktop version of a site might be difficult to view and use on a mobile device. As a result, having a mobile ready site is critical to your online presence. In fact, starting in late 2016, Google has begun experiments to primarily use the mobile version of a site's content41 for ranking, parsing structured data, and generating snippets.
In the last 10 years, the digital landscape has changed significantly. People are phasing out desktop and laptop computers to search the web and interact with content. Instead, they are picking up their mobile phones and tablets. What’s more, digital technology is cheaper today than it’s ever been before; there are virtually no boundaries on how, when and where people can interact with content.
