Link building

The more links to a website, the better it is regarded by search engines and the higher it ranks in rankings. Moreover, simply building up links is no longer enough - for effective promotion, search engines need to see real link conversions and record good behavioural links. 
Backlinks are links that take you from one site to another. 
Backlinks are valuable for three main reasons.
1. Ranking
2. Ease of finding them
3. Referral traffic
Backlinks exist to direct people to what they are most interested in, so people follow them. 
If the donor resource is 5 years old and the attendance is very low, the trustworthiness of such a site for search engines is close to zero. As your chances of getting to the top, respectively. If the user factors are high for your topic, the search engine will be more favourable to such a site (and increase its ranking based on its usefulness for people), and therefore - to you.
A lot changes in SEO, but interesting and useful content never goes out of fashion. Of course, 'quality' articles can vary, but in our case, the one requirement is that they should make readers want to share the content with others.
People tend to click on more prominent links, so some links on web pages provide a higher level of authority than others. Be sure to keep this in mind when working with links. If you see your link ending up at the bottom of a web page or in a sidebar next to dozens of links to other sites, you are better off using a web 2.0 backlink service  .
The effectiveness of a quality backlinks strategy for your site has not changed over the last five years, but the methods of getting them have. Successful digital marketers incorporate backlinks into their strategy from the start of a project.
Find out where your competitors are getting links and replicate their efforts. Your competitors are those sites that are already at the top of Google for the queries you are interested in. Your job is to find (and recreate) the backlinks that helped them get there.
Creating guest blogs and posting your unique content on other sites will not only help increase your reach and drive traffic to your site, it will also strengthen the authority of your resource. 
The benefit ultimately lies in establishing long-term relationships with a more established and well-known website and brand. By building relationships with the big players, you open the door to even more marketing opportunities, including joint projects, shared conferences or even products.Infographics are an easy way to instantly elevate your content from good to truly valuable to your audience. However, creating infographics without the right resources is difficult - it takes writers a long time, especially when they have to gather the data for it themselves. For this reason, many of them find and use other infographics in their materials instead of creating their own. This is a feature you can use to get backlinks to your site.
Link mass dynamics is a marker of site quality. If no new links appear in the profile, it means that the site is not developing well. Projects with quality content regularly get new backlinks to their profile.

In some niches, projects can rank at the top of organic search results without links from authoritative sites, but this is the exception to the rule. If the competition is high, it is almost impossible to beat the competition without a good link-building strategy.
Therefore, the effectiveness of link building depends on the quality of link management. If the profile month after month does not appear new backlinks - search engine algorithms will draw the appropriate conclusion.
To get backlinks, reinvent the wheel is not always necessary. One of the easiest ways to get a positive result quickly is to check your site for missing links. Losing hard-won backlinks can be frustrating, but getting them back is often not as difficult as you might think. They can be lost for many reasons - a problem with the donor page itself, a redirect appearing on the page, or the author deleting the link for some reason.
Whatever the case, it is worth taking the time to try and reverse the loss. After all, the link to your site didn't just appear, and the owner of the other site may not even be aware that the donor page you wanted was removed for some reason.
Another easy way to get a quick result is to look for mentions of your brand. When someone speaks positively about you, it's a great way to get a backlink from them. If someone mentions you on another site, chances are they already see some value in your product or service, so getting them to link back to your site won't be hard. Especially since it might also be useful for visitors to his site if they want to know more about you.
When promoting websites, the webmaster has two global tasks - creating quality content and maintaining good backlinking dynamics. Only comprehensive work on the two areas will produce the desired result.
Project owners with minimal SEO experience often worry that they will not have enough budget for link building and focus on free approaches to getting links, but this is not the case.
If a project regularly publishes quality content that other sites will want to share, link-building will grow organically. Creating research, infographics and other downloadable content can therefore give good backlink growth.
Search engine algorithms regularly scan the link profile, and if they see link churn every time, a negative result will not be long in coming. It may not happen immediately, but the likelihood is very high.
