Like you I am a scientist and like you did in the past, I am currently working on translating great scientific literature into tips. In my case it’s child development research into play tips for parents. I can already see that the outcome of my experiment is going to be the same as yours. Great content but who cares. I hadn’t even thought about my key influences. I know some important ones, but don’t see how they would share my content. I thought I was writing content for my potential customers. Is your SEO that works course the same as the content that gets results course? Sorry if I sound a bit dim asking that question.
SEO is also about making your search engine result relevant to the user's search query so more people click the result when it is shown in search. In this process, snippets of text and meta data are optimized to ensure your snippet of information is appealing in the context of the search query to obtain a high CTR (click through rate) from search results.
Note: Some of the high ranking pages may be on famous websites (Domain Authority of 90+). If so, it’s unlikely you’ll outrank them …unless, their high ranking page isn’t very focused on the topic. If you can make a higher quality page that better indicates it’s relevance by using the keyphrase, you may be able to outrank them! More on using keywords in a bit…
For our client: We only used a smaller quantity of very high-quality link building each month. So, for example we only built 40 of the best links each month to supplement the work we were doing on the content marketing front. We also invested heavily into tracking competitor backlink profiles, using Majestic SEO and Open Site Explorer. We worked out how the competitor's acquired specific backlinks, then by using outreach and content creation we obtained these links.
It’s important to note that Google is responsible for the majority of the search engine traffic in the world. This may vary from one industry to another, but it’s likely that Google is the dominant player in the search results that your business or website would want to show up in, but the best practices outlined in this guide will help you to position your site and its content to rank in other search engines, as well.
That second link will still help you because it will pass extra PR to that page. But in terms of anchor text, most of the experiments I’ve seen show that the second link’s anchor text probably doesn’t help. That being said, Google is more sophisticated than when a lot of these came out so they may count both anchors. But to stay on the safe side I recommend adding keywords to navigation links if possible.
I’m not sure that’s natural link building/earning and I feel Google would have a problem with webmasters getting hundreds of links from different entities which were all identical? The websites embedding the images may not even know they are linking to you. Google in the past recommended these kinds of links are nofollow: https://searchengineland.com/googles-matt-cutts-i-recommend-nofollowing-links-on-widgets-169487
The majority of web traffic is driven by the major commercial search engines, Google, Bing, and Yahoo!. Although social media and other types of traffic can generate visits to your website, search engines are the primary method of navigation for most Internet users. This is true whether your site provides content, services, products, information, or just about anything else.
