General

• What is Linkdu?
  Linkdu is a new service that enables webmasters and website owners to quickly and effortlessly build up good quality, relevant backlinks, by agreeing to display a small amount of links to other user's sites on their own pages.
  
• Isn't Linkdu just another link exchange directory?
  Not exactly. Most link directories work on the principal of having a single "Links" page, that is populated with links that are vaguely related to your site's topic. Linkdu places links on already existing content pages that have a relevant relation with your topic.
• Are the links reciprocal?
  No. It is widely believed that search engines place less weight on simple "you link to me - I link to you" exchanges. Linkdu uses sophisticated algorithms to create multi-way links between the pages and sites in the system.
  Linkdu will get you links in this order:
  1.- From websites in your language and related to your site's topic
  2.- From websites in other languages and related to your site's topic
  3.- From websites in your language and other topics other topics that you select from the list of topics available
  4.- From websites in other languages and other topics that you select from the list of topics available
  Links will come first of websites with similar pagerank to your website and after that with Pagerank below your website with a maximum of 5 links from one particular site.
  
  
• I don't have any pages with PageRank, will you accept my website?
  Linkdu only accepts pages that are already indexed in Google no matter the PageRank your site is. However, you can purchace Links directly, which will eventually earn you PageRank.
• What are Link Variations?
  Link Variations are the URLs and link text you define for your backlinks. You can have an unlimited number of variations within a campaign, and Linkdu will randomly choose one of them when placing a backlink.
  
• What is your stance on user privacy?
  We take user privacy very seriously. In short, we will not,under any circumstances, use your information or data for any purpose other than exchanging links with users of the Linkdu service. You also remain completely anonymous within the system, nobody can browse your sites or links.
  
• There's a feature I really think you should implement. Can I request it?
  Yes. We love to get feedback from our users about the service we provide and are constantly looking for ways to improve. Get in touch with us via our contact form on the Contact page. We can't guarantee that the feature or improvement you request will be implemented, but we do take all user feedback very seriously.

Getting Started

• Is it easy to get up and running?
  Of course it is! Once you've registered your free account, simply head over to the Link Display Codes page and download the corresponding package. Depending on your site, either install the module or paste the code into your pages - and that's it! We will then automatically "discover" your site and it will show up in your dashboard. All you have to do now is set your site's topic and tell us how many links you'd like to display per page - we take care of the rest.
• I registered for an account but lost/didn't receive the activation email. What can I do?
  Please use the contact form on the Contact page and we will proceed to activate your account.
• I added my site but no pages have been found. What can I do?
  You can try going to your site and clicking on some of the internal links, this speeds up the discovery of your pages. .
  

Displaying Links

• Can I choose to display links from sites in a certain language?
  Yes, you can choose to display links in a specific language if you wish. Please note that for more obscure languages, there may be few or no links available.
• How many sites can I add?
  As many as you like.
• How are links displayed on pages?
  By default, links are displayed as plain text anchors. We provide simple yet comprehensive options for controling the layout, should you wish to display links horizontally, vertically, as a list, etc.
• Can I choose what topics I display links from?
  Yes, you can filter out links from undesired topics.
• Why does my site appear twice on my dashboard?
  If your site appears twice in a format similar to this:
  
  www.mysite.com
  
  and
  
  mysite.com
  
  it is because it's accessible from both the "www" and non-"www" domains and is therefore technically 2 separate sites. Search engines are known to dislike duplicate content, so it is recommended to configure your site to redirect all traffic to either the "www" or non-"www" domain.
  
• Why does the message "DEBUG-YOUR-URL" appear on my pages?
  The debug message appears when you have enabled debugging in your site settings. It is used to verify the exact URL that the page reports back to the Linkdu servers. This can be useful when trying to determine why a page has no links displaying, or when determining what your real home page URL is (for example, on most Joomla sites, the home page URL is "www.mysite.com/index.php", even though you enter "www.mysite.com" in your browser to visit it.
  
  During normal use, you will want to disable the debugging, which can easily be done by un-checking the option in your site settings page (it's near the bottom).
  
• My dashboard reports that you have placed links on my page but I can't see any links. Why?
  We employ caching on users' sites to improve performance. This means that when we place a link, it might not be visible until the site's cache clears. Caches are cleared automatically at least every 24 hours.

Link Credit

• What is Link Credit?
  Link Credit is the "currency" that we use throughout the system. You automatically earn Link Credit by allowing links to be placed on your pages. The more links you allow, the more Link Credit you will earn. This can then be spent on getting relevant backlinks. Google PageRank also affects the rate of Link Credit that you earn/spend. Getting backlinks from higher ranked pages will cost more Link Credit, but you'll also earn more by displaying links on your higher RageRank pages.
• How much Linkdu are links worth?
  A link placed on a page is worth a set amount of Link Credit . The table below shows the values of links placed on different pages:
  
  

  PageRank of page	Value (per link)	Amount earned for placement
  PageRank 0	0,20 Link Credit	0,1 Link Credit
  PageRank 1	1 Link Credit	0.8 Link Credit
  PageRank 2	2 Link Credit	1,6 Link Credit
  PageRank 3	5 Link Credit	4 Link Credit
  PageRank 4	10 Link Credit	8 Link Credit
  PageRank 5	25 Link Credit	20 Link Credit
  PageRank 6	50 Link Credit	40 Link Credit

   
  When you display links on your pages, Linkdu will deduct a small percentage of the above value before crediting your account. This is to ensure that we have a small reserve of Link Credit in the system to be able to sell to those who choose not to display links on their pages.  
• My account reports that I have a negative amount of Link Credit . Should I be worried?
  Generally no. We allow accounts to drop slightly into negative Link Credit in order to accommodate daily fluctuations such as PageRank changes or pages being removed from the system. Linkdu continually monitors your available Link Credit and will try to balance it out. In a situation where your Link Credit drops to well below zero (for example: because you removed a site from the system or deleted some pages that had links placed on them), Linkdu will give you some time to try to recouperate the lost Link Credit . If you fail to do so within a specified amount of time, you will have some or all of your backlinks removed in order to balance your Link Credit out to zero again.
• Can I sell Link Credit ?
  No, it is not possible to sell Link Credit .
• Can I buy Link Credit?
  Yes, iIf you prefer not to display links on your pages or simply want a backlink boost, you can become a subscriber and purchase Link Credit directly.
  1 Link Credit costs $1 (USD). We also offer discounts on larger amounts.
  Creating a subscription will not only give you extra Link Credit. When you buy Link Credit it will increase your Link Credit account monthly, so you will be able to get more links from Linkdu every month.
• Can I cancel my Link Credit subscription at any time?
  Yes. Just log into the Paypal account that you used to purchase your subscription and cancel it. You will still retain your bought Link Credit until the end of the subscribed period.

Getting Backlinks

• Are my backlinks permanent?
  Generally, yes. Once you receive a link back from another page, that link remains there as long as the page still exists, meets your requirements and you have sufficient Link Credit to maintain it. Occasionally, a site owner may reject your link, or delete the page itself. In such cases, the link credit you spent on that link is returned to your account and the system will look for another page to place your link on that matches your requirements. If a page's PageRank value changes, but still meets your requirements, your Link Credit balance will automatically be adjusted.
• How can I be sure of the quality of the backlinks I get?
  Iif you receive a link from a page that you don't want, you can easily reject it and we will automatically go and find you another link. Similarly, you can just as easily reject links that are placed on your own pages.
• I've earned some Link Credit, now how do I get backlinks?
  All you need to do to start receiving backlinks is create a backlink campaign. This can be done by clicking the "Add Backlink Campaign" button on your dashboard. You need to specify at least one URL (and link text) to use in your campaign, but you can create as many as you like in each campaign.
• How many backlink campaigns can I add?
  As many as you like.
• I have received a backlink but when I visit the page I can't find my link placed anywhere. What can I do?
  Some users may try to hide or obfuscate the links on their pages. Search engines don't generally take into account CSS styles and javascript, so Linkdu only checks whether the link exists in the source code of the page. We leave it up to you to determine if the site is engaging in shady practices when it comes to displaying links. If you think a page is going to lengths to hide or disguise your link, you may reject the backlink. We will manually investigate such rejections, and take necessary action against any offending sites.
• Why have some or all of my backlinks been removed?
  Sometimes, other users will reject your link from their pages. We will inform you when this happens. Occasionally, you might see many "backlink removal" entries in your updates. This probably means that the system has removed some or all of your backlinks in order to balance your Link Credit total to 0.
  
  Linkdu will always try to keep your available Link Credit as close to 0 as possible. It will let you drop slightly below 0 (about -1.00) if you don't quite have enough to afford a link. The situation can also occur that your Link Credit drops to well below 0. This could be due to one of several reasons:
  

  1. You rejected one or more links from your own website (meaning you no longer earn the relevant credit for displaying that link).
  2. You deleted a page from one of your websites, thus removing all the links you were displaying.
  3. Other users rejected their links that were placed on your pages.
  4. We repeatedly could not find your links on 1 or more pages when we checked that links were being displayed. This will eventually cause your page to be deactivated for a period of time.

  
  
  

Compatibility

• What kind of sites will Linkdu work with?
  Linkdu's system will work on almost any site that runs in PHP or .NET. For added convenience, we have developed ready to install modules for the popular content management systems Joomla and Wordpress.
  
• My site is in plain HTML. Can I still use Linkdu?
  Probably! If your server runs Apache and PHP, you can try adding the following lines to your .htaccess file in the root of your site*:
  
  

  AddType application/x-httpd-php .html .htm
    addhandler x-httpd-php .html .htm  

  
  
  This tells the server to process all files with the extension .html and .htm with PHP.
  From here, it's a simpe case of pasting the PHP Link Display Code into your HTML pages (don't forget to wrap them in PHP  tags).
  
  *Always backup your files before making any changes!
• Do you support Blogger/Blogspot?
  Unfortunately, we do not support either platform at this time due to technical limitations of those platforms.

• I have lost my password. What can I do?
  On the login page, click the "Lost password?" link. We will then ask you for the email address that you registered with. Once provided, we will send a new password to that address.
• How do I cancel my account?
  We sincerely hope that you benefit from using Linkdu, and that it has a positive impact on your search engine rankings. If, however, you no longer wish to use our service and want to cancel your account, just use the contact form on the Contact page to let us know, and we will immediately remove your account, sites and information from our servers, no questions asked.
