Suey, having links to other sites is important in getting your site noticed by the search engines. However, the links that are most important to you are links into your site, ie, links from other websites. It's not really a good idea to just copy and paste a load of links onto your page and hope other guys will reciprocate, sometimes they wont want to, other times they might just forget to. If you can, try and think of a link as a vote. So now you are effectively voting for 20 other sites and nobody is voting for you.
My advice is to just add one link at a time. Email the owner of that site, compliment them on their site and ask them would they be interested in exchanging links with you, if they are, well and good. If they refuse, remove that link. Move on to the next site and continue. Take it from one who knows that this process can be a right royal pain in the ***, but it is in my opinion, a necessary evil, and just one of the steps required to capture the eyes of the search engines. Once you've started your linking strategy, think big, if you can get a link from a well established website with pagerank, it is much more beneficial than getting a link from a new website with no pagerank. I'll expalin this in detail some other time.
Open advice to all readers:
In order to make your site more 'link-worthy', make sure your site is complete, all pics, etc are optimised, you have spell-checked your text and all your own internal links are working. If your site looks reasonably well presented, most other nail and beauty sites will readily link to it. Conversely, if it looks amateurish, unfinished, has spelling mistakes or takes an eternity to load, dont be surprised if you get a refusal, or like I said earlier worse than that, they just dont bother replying at all and now you dont know where you stand. There's tons of help available to assist you with any probs you might be having, both here in The Nail Geek and also in The Nail Directory. If anyone is still having problems or you just dont understand what I'm saying, gimme a shout and I'll get back to you.
