Using the Hash in your Back Links
Post from: SEO
So recently I have been receiving a lot of inquiries for a keyword I don’t care to rank for.
At first I thought it was an SEO friend playing a practical joke on me, but after doing some extensive research I found out exactly how it was done.
So first let me show you the keyterm…. (vulgar words were whited out)

Yes I know…you’re probably laughing your head off…cuz I’m ranking at #4, and yes I am receiving about dozen visitors A DAY!
Well as you can see…. my title tag or description does not contain the key term.
I first checked the page and thought the key term would be in the comments, but I found nothing. I also check the cache of the page to see if Google had an old copy of the page, and didn’t find anything.
I checked the file manager (FTP/cPanel) for the site and didn’t find anything suspicious.
Ok……so now I knew I had to check my back links. For those of you that don’t know….you can rank a page AND the content doesn’t even have to be on the page. GASP! Yes it’s true…..but we’ll save that for another post for the ‘SEO is all about content’ google brainwashed readers.
So I ran a ‘back link check’ on Yahoo (and other services) link:centuryhouse.net/lower-bounce-rate/and found nothing unusual.
I started running other commands to see if my site was hacked, and found NADA! (site:centuryhouse.net/lower-bounce-rate/ keyterm)
So I ran an allinanchor check to see if my page had any back links with that key term as the anchor text
allinanchor:”keyterm” – my site again appeared on page 1.
I reran the back link check on my whole site and found no such keyword!
So right about now I was upset….and started tweeting to @MattCutts (Peon at Google). He used to reply to my tweets and even answered a 3-4 questions on Youtube GoogleWebMasterHelp. I figured he was still upset after he manually devalued my back links, and knocked my site from being in the top 12 for the keyterm SEO to I dont know where after I posted Google Just Killed Your Online Business and I asked him to Sphinn it.
anyways….back on topic.
So after a couple of days of ranting on @RobertE I thought about running the URL in quotations. Here’s what came up

At first I was a bit sad after seeing that nobody was running any PPC on my search term, but then I saw something weird.
I already know that spammers build back links to a profile page but now they were building back links to their spam comment on my page!
So I went on Yahoo just to see if any of their back links showed up to the spam comment left on my blog (that included the key term)

as you can see…they built at least 9 back links to the comment page.
Now for those who don’t know why a site uses the ‘#’ on a url….here’s why
If you give someone a link, and you don’t want him to read through the hundreds of comments…you can give him the exact comment link w/hash which will take him DIRECTLY to the comment on that page. Site owners also use it to take you to a particular section of a website. For example, the Back to Top link/button normally has a hash ‘#’ in the URL that will take you to the top of the page.
So the spammers were hoping to rank their comment page on Google, and have individuals go directly to the comment instead of having to read the whole article to get to the comment. Makes sense?
SEOs/Search Engines on the other hand use it for another reason. The ‘#’ aka hash is used to have all the link juice point to the URL that is before the hash
centuryhouse.net/lower-bounce-rate/#comment-21718 If any back links point to this URL, all the juice will go to the green URL
This is very useful if you have affiliates or you are an affiliate promoting a site, and you’re using tracking ids.
centuryhouse.net/?tid=21718 all back links pointing to this URL will have the juice flow directly to this page which is NOT recommended (especially if all the tracking id pages are the same)
The tracking ID page should use the hash so if any back links point to it then all the juice will go towards the main URL not the tracking URL
centuryhouse.net/#?tid=21718 is the correct way to use the hash so all the juice points to the green URL.
Sooooo
the spammers messed up because they forgot about the SEO factor of the hash. They also forgot that Search Engines do NOT index what follows a hash. They only index what comes before the hash.
So I’m thinking if you want to hide your back links from your competitors, you can build back links to yourdomain.com/#whatever and you’ll know that domain.com will get all the juice. LOL Ok j/k I’m not recommending that
but I’m sure it’ll work.
So here’s my dilemma. I’m still ranking for this and still getting hits from this key term.
I’m trying to figure out a way to 301 centuryhouse.net/lower-bounce-rate/#comment-21718 to http://twitter.com/MattCutts
It seems the htaccess file is not recognizing the hash and not properly redirecting it. (I tried already)
