|Top 20 Stealth Links - Getting your url in front of Search Engines by nontraditional means|
Getting into the "URLs Live Every Where" mindset.
In another thread on Virtual Page Rank [webmasterworld.com], we talked about ways that you can link to a site other than a direct http href link or links that may not show up on the link command radar.
Lets start a list of the ways sites can link, refer, or point urls to your pages other than direct hrefs. Mainly, we are after ways that SE's such as Google may run into and use urls they find:
- another site links to your graphics ( img src=http://www.searchengineworld.com/gfx/logo.png )
- a site links to your css files?
- rss feeds and other xml feeds that people can link to without notice or referrals necc being generated.
- links in email that some se's can read (yahoo mail, hotmail, Gmail [webmasterworld.com])
- links marked with noindex
- links marked with nofollow
- raw urls within css or in css comments
- urls within meta data of graphics and video files
- urls within html comments
- urls within the head section, meta data of a html page, or alternate html entities (alt, name, id, etc)
- links or pages that maybe surfed while visitor has page rank engaged on the toolbar
- the target of a constructed, obfuscated, or encrypted js url (hidden until executed)
- links behind pay walls that Google can spider via webmaster tools
- Domains that have been 301'd with links.
- Links in Flash movies (games, quizzes, etc).
- non href'ed url's. (raw url on page http://www.webmasterworld.com)
- Links in any documents other than web pages e.g. .doc, .pdf, .txt, etc.
- blocking a page in robots.txt should make it blocked from bots, but they still spider it.
- Domain registrations/Whois and DNS data
- Links in form data.
- Links in other Google produced software (gadgets, widgets)
- NonTraditional pages (irc, twitter, UseNet, Yahoo, or Google Groups.
- Advertising links (AdWords/Yahoo), and other services like Maps.
What else? Wow - blew through 20....
I will update as we go. Thanks to everyone who pitches in...

16. Domains that have been 301'd with links.
Links in Flash movies (games, quizzes, etc).
its entirely plausible that websites could be credited for non-internet links. There is no logic that says the value of a website is determined only by its internet presence.
Would this count?
(it doesn't take much IMO)
Would http references in the cite attribute count?
yes pg1 it would. I guess I consider that "meta" data like alt or name, or id.
Links in any documents other than web pages e.g. .doc, .pdf, .txt, etc.
blocking a page in robots.txt
non-google toolbars accessing the page you view
unprotected traffic stats
What about links in desktop widgets like the Vista sidebar - that how I got to this page, when Brett twittered it.
I guess what we may be talking about here is content discovery (although that doesn't necessarily mean passing much value) and attribution (that should always pass value, right?). For a search engine, it makes sense (to an extent!) to pay more attention to URLs that other people are paying more attention to.
I think we've covered most of the common ones and also the less common ones :) but a few that come to mind:
- Domain registrations and DNS data - Google have access to newly created domains, and also to DNS files, which will contain references to website hosts - some more frequently than others
- OCR - Google have mentioned this a few times (in connection with PDFs, for instance, and many images contain "watermark" URLs and suchlike).
Links in contextual ads
Links written on billboards, cars and other outdoor objects with help of Google Map.
great thread, unfortunately I don't have anything to contribute (it seems to have all been said), but great, great posts.
Thanks Brett, this is why I come to WebmasterWorld frequently, I'll be bookmarking this one :D
Well, I think content discovery is ultimately what we want to discuss. If a SE can't get at the link, it probably shouldn't be in the list.
Aps are interesting. I thought about it a long time (such as twitter aps), but I don't see a method of that url getting into a se bot. How could it?
You know Dinkar, you may have something there. We know for a fact, that Gbot can read text inside of graphics (Google Catalog proved that in spades). Do you think they are running OCR routines over the Google Street View maps? Then they could feed any hits, back into Google maps in order to increase the quality of maps somehow.
It is all in the community Greenleaves. Just trying to give back some of what I get.

Big time. Nice catch.

Here's something I asked Matt Cutts about at Pubcon in Austin - URLs that Google now discovers by spidering forms. Matt confirmed that such "links" send PageRank. Google establlishes a virtual link on their back end when they find something through form navigation and they add that virtual link to the webgraph.
Seconded, Ted - perhaps the wider category is 'URL manipulation' - i.e. if site.com/?one-word exists, then perhaps so does site.com/?two-words.
Pretty much all of the form spidering I've seen is essentially manipulating GET parameters.
Google gadgets is a mighty good place for a link discovery
This discussion is straying away from inter-site linking, and all over URL discovery... but here are a few more
URLs discovered in any other HTML attributes, like
<img onerror="http://www.example.com" lowsrc="http://www.example.com"/>
for a full list of all possible ones, just take a look at the HTML DTD
... and many more
(incidentally, all of these can also be targets for XSS, but that's another topic)
URLs inferred by parentage:
http://www.example.com/dir/image.gif => http://www.example.com/dir/
URLs used in CSS:
URLs used in conversation via Instant Messaging and Chatrooms (assuming suspiciously that they are not very private)
Tweets and statuses and other user-entered content all over the www
brute-force scraping of tinyUrl et al
the URL set as your "home page" in your browser
*your* Browser History (yes, it is possible to scrape it using some nifty and unobtrusive JS+CSS techniques)
Referrer info given on an outgoing link.
Logs (either directly available or via some sort of statistical package.
|Do you think they are running OCR routines over the Google Street View maps? |
They have technology and resources ($$$$$); so if they aren't doing it now, then they will start doing it anytime.
I'm a bit confused here....
Is this just a "let's list the various link types" for fun thread, or are you implying that there is some value to some of the link acquisition methods described above?
Could you put a "*" next to the ones that you feel are most worthy of attempting to get (of course only the "moral" ones).
These types of links obviously cannot make up for good solid link building skills....but on the rainy days when no webmasters are wanting to reply to my link requests.....would one or two of these suffice to build up my link profile?
Kind of like how a weight lifter dude goes on vacation and there are no weights for him to work out with in the hotel he is staying at for 2 days....so he borrows his girlfriends "thigh master" for a day or two?

Your GMail Account
Your Google Toolbar
Your Google Chat.
Bookmarks (even "private" ones) from services such is Delicious etc. (or that doesn't count in this context?)
Thanks 2clean, httpwebwitch both of yours are covered in one form or another.

This is a list of nontraditioal ways to get a url in front of GoogleBot or into the system. The value of doing so is a whole other discussion.
off topic - I cleaned 5-6 side topics in here. Feel free to start another thread with related issues.
What about detailed location/company-description data in google-maps?
And then google earth's .kml- and .kmz-files, particularly with respect to community-applications like the google-earth-war-project.
(Both might be subsumed under 19) or 23), but shouldn't we better treat each "format other than webpages" on it's own?)
Related: URLs may also be encoded as the "result" of those magical stereoscope images (if you definetly want to keppe SEs out;)
|Gbot can read text inside of graphics (Google Catalog proved that in spades). |
How about URL written on a graphic?

Honestly, it would not be surprised if G is doing this. However, if G is doing this and putting this as a factor in ranking a site, I seriously worry that Internet will become another world that is like our real world (By buying more ads/billboard ads offline, which is easily bought with $$$, a site ranks). There gone the long tail markets and left only manipulation by big shark in the real world.
In the above thread Brett said:
|I am pretty much convinced that links in Gmail pass some juice. |
Is there anybody who has noticed this?
How did you find it?
