Do you want Web Rings with that?

Wednesday, January 6th, 2010

Believe it or not, these leftovers from Web 1.0 are still popular on some websites. The idea behind a web ring is that sites are connected in random order to form a ring back to the original site. The webmaster gets a small piece of code that displays the sites, sometimes randomly, in the same ring. Usually, you have the option to click on one or more sites at the bottom on a web page to continue surfing on a related topic, interest or business objective. The web ring forms a “collaborative” group of sites.

Typically, since links rotate, or are displayed in random order, it is very hard to detect if any links are broken. It would take a lot of work on the part of the webmaster to check all the links.

Web Ring History

The web ring was born in 1994/5, created by Sage Weil, and is said to have died in 2001 under Yahoo’s reign. Ringmasters, the people who maintain and organize web rings, became more and more relegated to the background as “Web 2.0” emerged. Unfortunately, web rings were being associated with loud banner ads, annoying graphics, blinking text and horrible font colours. Read the whole story here.

The most popular web rings are grouped by topic so you can “surf” after starting from one of these sites:

Web Rings of the Future

It seems that web rings have an uncertain future. After 2001, there was a huge boom (after the bust) in the commercialization of the web. As corporate web presence grew, the homespun web got less and less popular. Web rings faded unless you were a Ringmaster with a strong community following. Corporations are a little less likely to bring a collaborative spirit to reignite the web ring concept. Lately – it’s all about keeping eyeballs on your site and converting them to sales, not surfing on a Sunday afternoon.

Link Exchange Scripts

Separated at birth, link exchange scripts are related to web rings. Link exchange programs have became very popular since the rise of web scripting languages. Many of link exchange scripts became fully automated which was a great time saver and greeted with enthusiasm. However, these automatic scripts cause many issues as well because webmasters forget to look after them.

Despite the fact that some link exchange scripts have the ability to “check the links”, these scripts are often abused by spammers because the webmasters are not as worried about them. Bad links get submitted daily as a result, ruining the user experience.

One of the first link exchange companies, LinkExchange, brought a little bit of “real-world” advertising to the warm, fuzzy world of Internet information sharing. LinkExchange was touted as a site that had an incredible reach to consumers looking for things and resources in a specific niche. Advertising on the site brought legitimacy as an ecommerce website. It also brought more eyeballs to whatever you were promoting – very powerful audience numbers before social networking came along.

Social Networking, Bookmarking Gadgets, Widgets and Scripts – oh my!

These methods have become the easiest way to share links when compared to other mentioned in this article. However, so may webmasters miss this aspect (isn’t StumbleUpon.com just a random web ring after all?) Despite that, URLs may look real in the browser but many of them are generated using JavaScript; this makes some links invisible or some of them broken to web robots like GoogleBot. The software mentioned above should not be avoided, but we’d like to emphasize that scripts and software usually cause linking troubles.

What should you do to be safe? “Nofollow” everything you find suspicious on your site. If social bookmarking has a specific URL, you can hide that from robots using robots.txt. Also, always check your site using LinkAider, our reporting module will provide the reports you need to fix broken or bad links.


Bad Links and other Hidden Hacks

Monday, September 28th, 2009

Do you have an open source Content Management system? Usually it’s a great help to have content generated by users and use the open source code capabilities to develop what you need. Unfortunately, more and more sites are getting hacked by search engine spammers. They hack in and code their bad links, exploiting security holes in the open source code. The innocent webmaster has no idea.

Webmasters remain unaware because the links are hidden from human eyes – only visible to search engine robots in order to grab higher positions in search engine ranking. MIT’s Technology Review recommends:

“that anyone running her own website regularly patch the Web server and any software running on it. In the same way that you wouldn’t browse the Web with an unpatched copy of Internet Explorer, you shouldn’t run a website with an unpatched or old version of WordPress, cPanel, Joomla, or Drupal.”

How can LinkAider help?

LinkAider now has a Smart Advisory module that detects excessive linking to a particular domain. And since LinkAider is a robot, similar to Google’s bot and other spiders, it can see the invisible and detect the content for human eyes. For example:

Wordpress hacked

Links like this are invisible to human eye.

How do hacked sites and bad links hurt webmasters?

  • Posts and tweets that contain links to your legitimate site can be rejected if malware is 
detected – reducing your exposure and reputation at the same time
  • Sites get removed from search engine indexes completely
  • Sites suffer a drop in rankings as a penalty for including spam links

LinkAider’s Smart Advisory module can perform a bad link check and report back to the webmaster on how to contain and correct these code violations.

Beware of Cloaked Spam

Seobook has an interesting story about cloaked spam and how hard it is to detect and remove. A text-only option displays the links and keywords that are hidden on the site. Google has indexed a list of this particular hack on more than 20,000 websites. This Google Reader discussion thread reveals how unsuspecting people are affected by the hack.

What You Can Do: Establish a Routine

  1. Check if there are any suspicious links using LinkAider
  2. Perform some manual checks:

    “Google, through some of its products, offers webmasters some ways of spotting if a site has been hacked or modified by a third party without permission. For example, by using Google Search you can spot typical keywords added by hackers to your website and identify the pages that have been compromised. Just open google.com and run a site: search query on your website, looking for commercial keywords that hackers commonly use for spammy purposes (such as viagra, porn, mp3, gambling, etc.)”

  3. Perform your updates when you are notified – especially for the latest Content Management System currently in use.
  4. Do not use unknown plugins or themes.
  5. Monitor your site for new links or suspicious activity.
  6. Ask all of your third-party developers to follow this routine.

Subscribe to LinkAider in order to catch all of the hidden hacks and bad links before they catch you off guard.


Introducing smart reporting module

Friday, September 25th, 2009

We’d like to introduce you our smart advisory module that we implemented recently. Some of you may have already seen that, but we think that it’s worth a separate post.

Due our ongoing process of improving LinkAider in order to make it the best Swiss knife for webmasters we focus on providing the most convenient access to our reports. Some users are already happy using our smart filters to navigate through report data. However it is very easy to miss some crucial points to an unprofessional eye.

LinkAider’s advisory module tries to detect and report some critical issues on your site:

  • Huge amount of broken links.
    Having a couple of broken links is OK, so we tend to ignore that. Moreover, we don’t like to bug you every time we find a broken link. Plus you can access that report via web interface. However, having huge amount of broken links may seriously harm your site’s reputation. If you got that message from us – that means that things are really bad. Go and fix your site immediately.
  • Possible spam
    If you have a page with too many links to some particular host (more than your site’s average) we’d suggest you to check if someone hasn’t spammed your site (is there a lot of spam in comments or worse, if you have your site hacked).
  • Server errors/hosting problems
    These are serious problems. That means that your server is miss-configured and you may loose your visitors/customers. Moreover, if we find such errors in the front end (usually people don’t give LinkAider tasks to crawl their backends) – you should check if everything is working on the back side.
  • Huge pages
    You know how annoying it feels to wait while a page loads? Keep in mind that some of your site’s users are overseas and are using cheap and slow internet connection. This alert is more of advisory type, so if you have a really huge page and you believe that your users are patient and dedicated ignore it.

And here is a screenshot of sample report that you may see online

Smart reports in action (censored)

Moreover, these reports are sent to you via email when crawling task is finished. Hope you’ll enjoy this feature. And if you are not a user yet, subscribe now! It’s free! :)


Stranded on Highway “404″: 
How Broken Links and Linking Pitfalls Ruin your Rankings

Wednesday, July 22nd, 2009

Ever-increasing content demands from individual users and budget-conscious companies are changing how websites are managed. More and more people run their own blogs, websites, online software, or social sharing applications.

So, after more than ten years, you would think that the 404 error would no longer be an issue. Yet, as we all “Stumble”, build sites, code, and develop applications, bad links still sneak through. Unfortunately, even basic typos can affect website ratings and the quest for quality Search Engine Optimization.

Here are some types of bad links:

Inaccessible Links: Web spiders can’t index these links because they are coded into JavaScript or Flash. If they can’t be found, the search engines can’t index them. Think twice before displaying content this way. Talk your clients out of it altogether if they are asking for SEO and are truly content-oriented.

Also, these links won’t be available to people who need to alter their computer settings to accommodate poor eyesight or other disabilities. Translation software may also be affected by embedded links whose characters are unavailable. Making your site accessible to others is a courtesy that has indexing benefits, as well as good “public relations” for the site’s overall reputation – especially if you are promoting a brand.

Link Polluters: Spammers make comments and create links randomly to various sites to increase their indexing results. This may have very negative consequences if your site is one click away from a porn or warez (illegal software) site.

If you decide to link to other sites without checking them out, SeoMOZ’s ranking factors report says that external links to low quality sites may impact your search engine rankings. Investigate your links – are they related to the message you want to get across? Do they contain good quality content? How do their own links score when you evaluate their rankings and other data? Google states:

“some webmasters engage in link exchange schemes and build partner pages exclusively for the sake of cross-linking, disregarding the quality of the links, the sources, and the long-term impact it will have on their sites. This is in violation of Google’s webmaster guidelines and can negatively impact your site’s ranking in search results.”

Broken Links: Even minor disappointments (like 404 pages) will drive away potential visitors and customers.  They might even find a competitor because of a typo. Have someone else scan your code and an end-user test and re-test your links.

Think about your print media too. Work closely with your marketing team to ensure that everything is ready. Don’t spend the money on a colour ad and have a typo, broken link, or a URL that is not up and running. Test, test, and test again.

Untrustworthy (Hidden links): Some people have embedded white font text and used other style sheet formatting tricks to position key words or other links behind images and colours. This type of thing will catch up with you. Here’s what Google has to say:

“If your site is perceived to contain hidden text and links that are deceptive in intent, your site may be removed from the Google index, and will not appear in search results pages.”

One Way Ticket to Bad Links: 6 Examples to Avoid

  1. A Webmaster/Blogger re-uses a piece of code from the Internet, such as a WordPress plug-in for dynamic menu generation. The links are generated using script (flash).
    Result: Links are invisible to web spiders and all of the pages in the “drill-down” structure do not get indexed.
  2. A Webmaster/Blogger puts some external links on their website. The target domain URL expires and gets acquired by spammers.
    Result: Link to a porn or warez site directly from your website!
  3. A Webmaster/Blogger adds some links to YouTube, Flickr, etc. The targeted content is then removed because of a copyright infringement.
    Result: 404s
  4. A Webmaster/Blogger upgrades a WordPress installation and a plug-in malfunctions, such as a tag generation plug-in.
    Result: Many internal 404s (or even internal server 500s)
  5. A Webmaster/Blogger codes a typo or misspells a word in a URL.
    Result: 404s
  6. Automated link exchange software is being used at your organization.
    Result: Spam infiltrates the system. The final links page gets more than 100 links and your site gets flagged as a link farm.
