Backlinks vs External Links vs Referral Links vs Outbound links
-
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,

Value of Links? What is each link worth?
Morning Everyone, I just had this thought and wondered what everyone's opinions were in terms of link value in monetary terms. We'll assume for the purposes of this that the links come from contextually relevant sites and that the sites in question have got the Moz DA from being high quality and have a good quality incoming link profile. Its a bit of a theoretical question, but i guess imagine if the only way you could get links was to pay for them, what would they be worth to you. This is link value for SEO purposes, they will have in addition value from traffic from good sites, that no doubt varies wildly depending on topic. I assume everyone also agrees on: The first link from a domain is the most valuable High DA sites are worth more than low ones. So could anyone who has an opinion on the link value suggest a monetary value for links. Its really just using a monetary amount to see how best to target my time. Here is my example of what might be expected, but I am hoping people with more knowledge will perhaps correct it. DA Rating First Link 2nd-5th Link 5th-10th Link 10Plus Links 5 $5 $2 $1 $0 15 $7 $3 $2 $1 25 $25 $10 $5 $2 35 $45 $20 $7 $3 45 $65 $30 $11 $4 55 $95 $45 $19 $5 65 $200 $100 $45 $6 75 $350 $120 $65 $9 85 $700 $240 $95 $15 95 $1100 $450 $200 $30

Does an external link to an image file on my site help my SEO?
I found a few websites that are displaying images from my site. Curiously, they have also linked these images to the source image file on my website. I found these because Moz showed these sites in my list of backlinks. I assume that means it impacts my Domain Authority. But does this actually help me in search engines since it's not linking to a page on my site?

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

Hidden Backlinks
Hi, I hope someone can help me with this. We have a competitor who appears to be ranking No1 for a competitive search term with a very lame site and above some authoritative sites. He has been here for some time as well. When we check out his back link profile through OSE, Majestic and Ahrefs they show as only 3 backlinks from no PR sites. However, someone pointed out that they could be using a link network that is blocking every crawler apart from Google, Yahoo and BIng. I would like to know if there is a way to confirm this. For instance I know that we can use screaming frog to mimic Googlebot, however, if there a way to reveal the real backlinks to a site like this using any tools. Thanks

Footer Links And Link Juice
I'm starting to learn about link juice and notice in GWMT > Traffic > Internal Links, that the list is in this order by the links counted on each page. Some are in the footer and some are in the header, with some being more important than others commercially i.e. /register /privacy /terms /search /sitemap /disclaimer /blog /register So I am wondering if I should add a 'no-follow' attribute to the footer links i.e. privacy, terms, disclaimer and leave the others as they are? Does this help retain link juice on each page where the links appear? Or am I missing the point all together? This is my website: http://goo.gl/CN0e5

Changing links
Hi guys i wanted you views on changing the anchor text of links. I have quality links coming in but with year terms such as 2012 in there, if i want to change them all to 2013 for example would it be badly seen by Google? I cant say i feel comfortable about doing it but they are my links and are related to our products. Any advice much appreciated.

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>
