Well firstly, good domain name by which I mean short one but abc.im to a link shortening website I don't know. Doesn't sync much.
Coming to the website,
- Make it a fluid and responsive layout. This is what people are looking for in a website these days.
- The text box to enter the URL is to the left but not in the center. Do fix it.
- There is no proper favicon, so get one done and add it up asap.
- Your site hasn't even started to work fully and you added ads already! That's a bad idea, remove them asap.
- Check this
http://gtmetrix.com/reports/abc.im/xT9kTSHa once and fix the things to achieve maximum page load and page speed.
- Shortened URL says "http://www.abc.im?0" which is kinda weird don't you think ? Make it more user friendly.
- And in the statistics page it shows powered by iuv.be. What's up with that ?
- As of now API works fine but it has to be changed when u change the permalinks.
Good luck with the website and hope to see the changes.
Regards
