Just give it time and they will show up. It took about a month for my links to start showing up in Google.
I thought this might help others...
When I started, I had zero links and wasn't indexed - brand new site... I probably blast to around 5000 sites every 3/4 days, but some of them will be the same domain - not ideal, but I'm new and just making new lists....
After 1 day, I had 1 link on yahoo

and was indexed by google.
Day 2: I started showing up on page 2 of my main phrase - it's not extremely competitive and the phrase is an exact match to the domain, a search comes up with just less than 4million results, but its not a massive competition spree to the top of the list!
Day 11: This was when the dip happened, i'd been loitering at the top of page 2 until this day, and then the home page dropped off the face of the planet. One of my other pages however was showing up at number 86. I continued the link building, if anything increasing it to more "little but often" with the lists I had. I had 1192 links when the homepage vanished.
Day 14: Jumped up to number 61 with a recorded 3373 links.
Day 15: Jumped to 57, with 3827 links.
Day 16: Page 1!!! Number 9 though, and the home page is still missing lol, but an improvement. Recorded 4148 links on yahoo.
Day 18: Today, not much change in number of links, at 4133 today but have stuck at number 9 since. Just checked Google links for the first time and have a mega 43 links!!!
I will go through one of my 40000 unchecked lists now with the site, which is kind of what i've been doing every couple of days... the 40000 links should produce around 2000-4000 extra auto approved links - not all on unique domains, but it looks like its working well.
I know it's probably better to do a sitemap search etc, and focus on pages with "comment here" etc - but I just tried everything that came up and there's been quite a few surprises...
For instance, there are a few pages that dont have comment boxes etc, and there are say 10 links on there in sidebars - all for my sites only, nobody else seems to have found them which is nice

Whether they will make a major difference or not I have no idea, but the work seems to be paying off with the volume of links being generated - it's just awaiting to see the results really truely on the SERPs...
Ive done link building before, and normally have to wait for the google dance every 3-5 weeks to see results, scrapebox seems to provide very good link numbers so far, but results are a little erratic...
sites seem to dip for one or a few phrases after 5-7 days, then boost back or if not higher after another 5-7 days, but I'm still waiting for "wow" results in truth, it's all very impressive and I can't see why results won't get any better, I guess it's just a case of how long it will take!
