The Guardian is experimenting with a new Twitter-based service, and would like your help to test it out. @GuardianTagBot is a Twitter account set up for our content API robot, TagBot. If you tweet it with a search term on your phone or online, it will then send you a link to our latest coverage that best matches what you were looking for. It's rather like playing fetch with our articles, videos, galleries and audio.

For example, if you tweet "@GuardianTagBot latest Arsenal news?", TagBot will match the words 'news' and 'Arsenal' against the content we have stored and tagged on our API, and return you our most up to date content on Arsenal FC.

This is a beta service however. TagBot will definitely make some mistakes, but it's here to help us check how well our tagging system is working. To help you get the most relevant results however, here are some quick FAQs:

How should I tweet TagBot?

TagBot will try its best to understand full sentence queries e.g. 'What's happening in the Middle East?' but it will probably respond best to more specific search-style terms like 'Middle East news', or 'Nigel Slater recipes'. TagBot might get confused if you are asking for news on Jordan the country rather than the latest antics of Katie Price, so you might want to be as clear as possible! Of course you can swear at TagBot too, but you might make it sad. TagBot will also struggle with personal requests like 'Will you marry me?'. It's not Siri.

How will TagBot respond?

TagBot will reply to your 'Mentions' feed by sending you an @ reply with a link to a results page similar to the one below. This will show you the most up-to-date content the Guardian has managed to find on the tag or keywords TagBot thought you were looking for, as well as asking for your feedback.

TagBot is only as good as the tags we have so if it returns something that's not relevant, that's probably because we haven't got a tag for it yet, so it's doing its best. However if TagBot replies with 'Sorry, no content' and you're certain we should have something, let Tagbot's puny humans know by tweeting @TagBotsHuman or emailing tagbot@guardian.co.uk.

A sample of the results you might get by asking TagBot a question

Can I give feedback?

Yes please! We'd love for you to let us know how well TagBot did getting the content you wanted, even if it's done a bad job. This will help us improve our tags in the future. So please let us know by clicking the 'I am a good Bot' or 'I am a bad Bot' buttons at the end of your results page. If you'd like to give more feedback, again tweet @TagBotsHuman.

Is there a maximum amount I can tweet TagBot?

There is no personal limit, but TagBot's batteries are only so powerful, so after responding to around 3000 queries a day it will fall asleep. The best way to know when this is happened is to follow @GuardianTagBot which will tweet status updates and let you know when it is dozing, as well as any news on new tags, and any interesting tag-related content it thinks everyone should know about.

If I follow @GuardianTagBot won't I be sent everyone else's TagBot replies?

No. TagBot will go and search for your query but send you an answer from one of his related accounts, @GuardianTagBot1, @GuardianTagBot2 or @GuardianTagBot3. In fact it's probably best you do follow @GuardianTagBot so you know when it's dozing so can't answer.

Will I get further updates on my query when you publish new content?

No, you will only get a response from TagBot when you initiate a new query, during this trial.

Are there are humans watching TagBot's account?

Yes - but only intermittently. This is a beta service so won't have Guardian's usual customer service standards. The humans can be contacted through @TagBotsHuman or through tagbot@guardian.co.uk.

Why are you doing this test?

The idea for a Twitter-based Guardian search client came from Guardian content development manager Nina Lovelace and was developed in collaboration with social media agency Smesh with input from the Guardian development and user experience team. We wanted to test whether in future we could provide a service by which users 'sign up' to get content updates through social media networks according to their favourite tags, eg Arsenal.

We're also interested in building new things that can help show off potential of the Guardian's Open Platform to users and potential content and commercial partners. If you've any other thoughts on how we could improve TagBot, please let @TagBotsHuman know.
