      Hello all,

      I was just wondering if you could explain the difference between all the links above? I'm confused as they all seem to be the same or similar and I would just like to clearly know what distinguishes them from eachother.

      Thanks for your help,

      Jayne

          Hi there!

          Let's say that you have website A, with the domain aaa.com ...

          Backlinks: Any link that points to a page within website A is a backlink (at least it is from YOUR point of view). These links could come from other websites, but also from within website A

          Referral Links: A referral can be a link that isn't from a crawable web. For example, a link in an email or from Facebook.

          Outbound Links: Outbound links are links that are meant to take you elsewhere. These are links that are going to direct you to another specific webpage or website altogether. Most, if not all, websites have outbound links.

          **External Links: **External Links are hyperlinks that point at (target) any domain other than the domain the link exists on (source). In layman's terms, if another website links to you, this is considered an external link to your site

          Hope this helps!

          Thanks,

            Backlinking Strategy

            link building link building whitehat

            I am particularly new to the field of SEO and Backlinking and I have recently started my own blog feel free to have a look (https://thehorseradar.com/). What I wanted to find out is how can I achieve a DA of at least 30. What should be my link-building strategy? & what steps should I take first? With an abundance of overwhelming info available online I have gotten really confused about what would work and what would not. If someone would lay out the steps needed to be taken, I would be extremely grateful! Thank You

            Sudden drop in external links... why?

            We had a lot of external links (2.5K, which was good compared to our competition), but in the last few weeks, it dropped 1.1K. I obviously did something wrong. What are the causes of such a dramatic drop like that? Questions, suggestions, ideas, anything is welcome at this point. Thanks!

            Do links on Reference.com and Ask.com count as backlinks?

            Hi there Just had a quick question about links on Reference.com or Ask.com. I have been looking at my competitors link profiles to get ideas of who and where I should/could be linking from. One of my main competitors seems to have links on Reference.com and Ask.com which are being listed in there profile. Reference.com are dofollow. Our site is also appearing on these sites, but the links are being listed under our profile. We have been up and running for more that 3 years now. The obviously have high DR and I think must be a contributing factor to their rank, having looked at other links in their profile. It seems strange because I thought these sites are effectively search engines and therefore wouldn't count towards your backlink profile? Can anyone explain? Would be most grateful if someone can. Many thanks in advance. Clojo

            DA vs PA when building links

            When building links to your site from other sites, what is more important or what weights more heavily? Say a site has a DA of 20 and PA of 34 for that page I want a link from. Say another site has the revese, a DA of 34 and a PA of 20. All things being equal, which site's link to me would be better? The one with a higher DA or the one with a higher PA for the on the specific page I would get a link?

            What is a good ratio of total links to linking root domains?

            Is 100 total links for every linking domain too high? I suppose I could also look at ratios of sites that are doing well in the rankings.

            A link with "return false"- OSE sees as a No Followed Link

            Hello, I couldn't find a clear answer to the impact on SEO for a link written in this way: [" class="expert_info" onclick="window.open(this.href);return false;">](w</span>ww.yourwebsite.com<span style=) [Does the "return false" act as a "no follow"? I came across this in our link data in Open Site Explorer which lists these links all as "no follows." However, an engineer I spoke to said that it shouldn't impact search engine behavior. Any ideas? Thank you in advance! -Sarah K.](w</span>ww.yourwebsite.com<span style=)

            Unique Domains vs. Total Links?

            At what point is there diminishing returns from getting multiple links from one website? Edit: To clarify, when doing competitor research I come across lots of sites that have say 500 linking domains with 5000 total links. When setting goals and calculating the types of links I should go after, I'm not certain which number is the one actually helping the site to rank.

            Iframes vs links

            Obviously, websites can link to another web site using iframes, and Google and other search engines do seem to have some capability to index the content. What I want to know is what is the difference in value passed between a regular link and an iframe link. <iframe src="http://www.targetwebsite.com/targetlink"><br /><br />will have the same page ranking effect on the target web site as this link: <br /><br /><a href="http://www.targetwebsite.com/targetlink">link</a><br /><br />Alternative, would it work to include an invisible actual link right before the iframe, like this: <br /><br /><a style="display: none;" href="http://www.targetwebsite.com/targetlink">link</a><br /><iframe src="http://www.targetwebsite.com/targetlink"/></p> <p><span style="color: #5e5e5e;">The reason is that we are building a product recommendation engine, for a branded cosmetology school in order to get our concept salons to link back to use and I was curious if creating a version they can use as an iframe will give us link benefit.</span></p></iframe>
