how to catch links through e-mail
Catching links in today’s web world is very important, and we know what good quality links can do for us, or even just ordinary links, well another method of catching links is to add a e-mail sign up form on your website, so therefore if people do find your website interesting, allow them to sign up for daily, weekly, or monthly e-mails.
Then try to create new pages periodically, and I would say the best method for this would be a blog, and whenever you have posted a really interesting blog with a great topic boom shoot the e-mail out, and you might catch some bait off that, so when your subscriber sees the e-mail, and if the topic was great, you might get some bait.
Bait can be a difficult thing to get sometimes, but i think this can be a great technique if you put your mind to it, specially if your website gets a lot of traffic, i mean think about it there is 500 people signed up to your news letter through e-mail, you only send them interesting blogs, or new pages about the website, that can draw some direct traffic.
Now its up to you to find out why they should sign up to your new letters
