Output keywords
If input keywords are important, the output ones are not lagged behind. By using output keywords we obtain credits which will give us more users. A site with a lot of input keywords is nothing without a flow of output keywords; it would be quickly running out of credit. So, as in case of input keywords, you have to try to register as many keywords as you can. You have to follow the same process with the output ones. In this case, unlike input keywords, you can add as many output keywords (having many and varied topics) as you like, including topics which are not related at all with your website or blog.
The subscription process for output keywords can be done in two different ways: through the process of 'Add Web' or by clicking on the 'Output subscriptions' icon we can found on the 'My Sites' screen.
In any case the following screen appears:

In first place we can appreciate a text box with some suggestions. They are about keywords ShareUsers considers that are related to the context of your site. To add words from here you just have to click on each word. As you may observe each word belongs to a category. You can add all the words the category has by clicking on 'Add all'. To see all the words the category has, just click on the triangle shown at its left side.
If words you are looking for are not in the recommendations box, you can search them in the ShareUsers data base. To do that you can use the following field: 'Search existing keywords'. Choose the language to which the desired word belongs and then introduce the word in the searching box.
For your consideration, it is important to know that the word you would like to add, belonging to a different language or not, has to be chosen as a word belonging to your language. For instance, if you want to add the "torero" word, though it is written in Spanish, if your blog is in English you will have to search that word in English language.
If the word or some words derived from that one are found, you can add them to your word list just by clicking on them. If no entries are found, you can add the word by using the 'New keyword form'. In this case, you will have to choose your website language, the word and a brief description concerning the word, and also to add some labels (short expressions describing the desired word). All the added words are accepted automatically, but they are later on monitored and those considered as inappropriate or incomplete are deleted.
There is a possibility in which a word you would like to add is already registered but having another meaning. For instance, imagine you run a musical blog and you would like to subscribe to the 'keyboard' word in order to receive visitors from websites or blogs dealing with musical keyboards. Imagine you attempt to search and only find a single meaning for the word 'keyboard' referring to computer keyboards. In that case you should add a new meaning for keyboard by filling up the 'Explanation' field which automatically appears when you try to add an existing word. The explanation should be a word or a short phrase expressing the difference with the main word. In case of musical keyboards you should add something like 'Music'.
Finally, we will see a list on the right side including all the words we have, or the ones we have added. Notice that words which are lately added have a lighter color. They are this color because they are added but not consolidated. In other words, changes have not been saved yet. You have to click on 'Save changes' to consolidate all changes you have made.
Thanks for your time
