Write articles rich in content. Quality articles will get ranked better in search results. Make sure that your articles address the needs of your readers, and that they can find all of the information they need in one spot. This is the most effective means for increasing traffic to a website; offering people something that they cannot obtain elsewhere, or at least, not to the level of quality that you are offering it.[1]


Relevancy is the first qualifier of a quality link opportunity. The next qualifying factor is the authority of the opportunity. Since Google doesn’t update PageRank (PR) anymore, you must rely on third party metrics. I recommend you use Domain Authority (DA) from Open Site Explorer, Domain Rate (DR) from Ahrefs, or Trust Flow from Majestic to determine the quality of your link opportunities. You should use all three tools if you can.
Thanks for the very, very in-depth article. I am a real estate agent in Miami, Florida and have been blogging all-original content for the past 21 months on my website and watched traffic increase over time. I have been trying to grow my readership/leads/clients exponentially and have always heard about standard SEO backlink techniques and writing for my reader, not influencers. Recently, I have had a few of my articles picked up and backlinked by 2 of the largest real estate blogs in the country, which skyrocketed visits to my site. Realizing what I wrote about, that appealed to them, and now reading your article, I am going to continue writing in a way that will leverage those influencers to help me with quality backlinks.
Dedicate some time to brainstorm all the different ways you can attract inbound links to your website. Start small –- maybe share your links with other local businesses in exchange for links to their sites. Write a few blog posts and share them on Twitter, Facebook, Google+, and LinkedIn. Consider approaching other bloggers for guest blogging opportunities through which you can link back to your website.
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.
Attempting to replace a dead link with your own is easily and routinely identified as spam by the Wikipedia community, which expects dead links to be replaced to equivalent links at archive.org. Persistent attempts will quickly get your account blocked, and your webiste can be blacklisted (the Wikipedia blacklist is public, and there is evidence that Google uses it to determine rankings), which will have negative SEO consequences.
You have also mentioned Quuu for article sharing and driving traffic. I have been using Quuu for quite sometime now and I don’t think they’re worth it. While the content does get shared a lot, there are hardly any clicks to the site. Even the clicks that are there, average time is like 0.02 seconds compared to more than 2 minutes for other sources of traffic on my website. I have heard a few guys having a similar experience with Quuu and so, I thought should let you know.
Search engines use complex mathematical algorithms to interpret which websites a user seeks. In this diagram, if each bubble represents a website, programs sometimes called spiders examine which sites link to which other sites, with arrows representing these links. Websites getting more inbound links, or stronger links, are presumed to be more important and what the user is searching for. In this example, since website B is the recipient of numerous inbound links, it ranks more highly in a web search. And the links "carry through", such that website C, even though it only has one inbound link, has an inbound link from a highly popular site (B) while site E does not. Note: Percentages are rounded.
