Users will occasionally come to a page that doesn't exist on your site, either by following a broken link or typing in the wrong URL. Having a custom 404 page30 that kindly guides users back to a working page on your site can greatly improve a user's experience. Your 404 page should probably have a link back to your root page and could also provide links to popular or related content on your site. You can use Google Search Console to find the sources of URLs causing "not found" errors31.
In the 2000s, with more and more Internet users and the birth of iPhone, customers started searching products and making decisions about their needs online first, instead of consulting a salesperson, which created a new problem for the marketing department of a company. In addition, a survey in 2000 in the United Kingdom found that most retailers had not registered their own domain address.[14] These problems made marketers find the digital ways for market development.

However, some of the world's top-earning blogs gross millions of dollars per month on autopilot. It's a great source of passive income and if you know what you're doing, you could earn a substantial living from it. You don't need millions of visitors per month to rake in the cash, but you do need to connect with your audience and have clarity in your voice.
The biggest problem that most people have when trying to learn anything to do with driving more traffic to their website or boosting their visibility across a variety of online mediums, is that they try to do the least amount of work for the greatest return. They cut corners and they take shortcuts. Because of that, they fail. Today, if you're serious about marketing anything on the web, you have to gain Google's trust.

Black hat SEO attempts to improve rankings in ways that are disapproved of by the search engines, or involve deception. One black hat technique uses hidden text, either as text colored similar to the background, in an invisible div, or positioned off screen. Another method gives a different page depending on whether the page is being requested by a human visitor or a search engine, a technique known as cloaking. Another category sometimes used is grey hat SEO. This is in between black hat and white hat approaches, where the methods employed avoid the site being penalized but do not act in producing the best content for users. Grey hat SEO is entirely focused on improving search engine rankings.

Unplanned content is an 'in the moment' idea, "a spontaneous, tactical reaction." (Cramer, 2014, p. 6). The content could be trending and not have the time to take the planned content route. The unplanned content is posted sporadically and is not calendar/date/time arranged (Deshpande, 2014).[88][89] Issues with unplanned content revolve around legal issues and whether the message being sent out represents the business/brand accordingly. If a company sends out a Tweet or Facebook message too hurriedly, the company may unintentionally use insensitive language or messaging that could alienate some consumers. For example, celebrity chef Paula Deen was criticized after she made a social media post commenting about HIV-AIDS and South Africa; her message was deemed to be offensive by many observers. The main difference between planned and unplanned is the time to approve the content. Unplanned content must still be approved by marketing managers, but in a much more rapid manner e.g. 1–2 hours or less. Sectors may miss errors because of being hurried. When using unplanned content Brito (2013) says, "be prepared to be reactive and respond to issues when they arise."[87] Brito (2013) writes about having a, "crisis escalation plan", because, "It will happen". The plan involves breaking down the issue into topics and classifying the issue into groups. Colour coding the potential risk "identify and flag potential risks" also helps to organise an issue. The problem can then be handled by the correct team and dissolved more effectively rather than any person at hand trying to solve the situation.[87]
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.
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 content42 for ranking, parsing structured data, and generating snippets.
On the other hand, marketers who employ digital inbound tactics use online content to attract their target customers onto their websites by providing assets that are helpful to them. One of the simplest yet most powerful inbound digital marketing assets is a blog, which allows your website to capitalize on the terms which your ideal customers are searching for.
