Instead of messing with blasting forums and comments, you should do this instead:
1. Make sure you are insulated from your site. Fake whois info or whois protection, dedicated email addresses, etc. You don't want angry emails/phone calls/threats. You'll get some eventually anyway, but best to minimize it. Make sure your site has a good security plugin and an SEO plugin (assuming you're on WordPress, which you probably should be).
2. Make sure your site has good keywords and good on-site SEO. Nothing you can do as a newbie will get you past a site with crappy keywords and poorly optimized pages. You already have a site, so hopefully there are good keywords for your niche! If you don't know how to do competition/profitability analysis or do on-site SEO there are plenty of threads about it.
3. Build some social bookmarks to your site. There are threads around here with lists of good BM sites, as well as BSTs that will take care of this for you for relatively cheap. You don't need tons. Even if you get a BST do a few yourself so you can get a feel for what your tools are up to later when you have this automated.
4. Build some Web 2.0s on high PR Web 2.0 sites. You can find some of those sites
here. Make sure they are sites that give ******** links/aren't SUPER picky (search for phpbuilt's Web 2.0 thread to find out which ones are super picky). You can worry about those kinds of sites later when you know more about what is going on. Add some random blog content once a week for 3-4 weeks before you start adding your own niche-related articles with backlinks to your site. Don't want to do this yourself? Check out some of the BSTs on this forum. Make sure they provide the account info. These sites will be the target of your more spammy blackhat stuff later. After 6 weeks just update these every once in a while (maybe once a month or put up a post to coincide with your new content). They will pay dividends.
5. Do some article marketing at high PR article directories straight to your home page. Do not buy 2k article blasts from crap directories to your money site. You'll also get a chance to see what format is needed to post to these directories for when you automate this later. These articles will also be good targets for later blasts.
6. Do some relevant manual high PR blog commenting. Search out niche-related blogs (if "related" is a stretch that's fine) and make an actual useful comment that is likely to get past the moderator. Trouble finding the right blogs? Check out the various threads about scrapebox footprints. All those are is a google query - you can do it all manually. While doing this you'll learn about how SB footprints work, which is awesome because SB is awesome and you will want it. Alternatively, you can go to a place like scrapeboxblasts.com (not affiliated - I think someone here on BHW runs it but I'm not sure) and order a couple hundred of their highest quality SB links, though they won't be niche related.
7. Get an article related to your niche and spin it. You can use one of the ones you already have for this. Turn that into a PDF and post it on some document sharing sites with links back to your site.
8. Go to Fiverr and pay 5 bucks to get someone to make a video out of a couple of images and words from your site/text from your article. Put this video up on video sharing sites with links back to your site.
9. Get the whole list of URLs you have links on and submit them to a crawling/indexing service such as Lindexed, Linklicious, or BacklinksIndexer. You can also just submit them to a ping site but I think most people get better results with dedicated services like those listed above.
Now you have a good base of relatively high quality links and a large variety of them to boot. When creating the links, be sure to use a few keywords and not just one keyword over and over. Don't just link to your homepage, do some inner page too. Once this is done you can start looking at sending lower quality links to these ones you just built to power them up.
I'm not going to lie, doing this stuff is time consuming and boring as hell. The temptation will always be there to just buy 5k crappy links from Fiverr because it seems like a good deal. It isn't, because you won't learn. You will not do this stuff much - certainly not manually - but you should do it all once or twice to get a good idea of what it takes before you automate it. I jumped right into automation when I started a few months ago and basically wasted three weeks and a good bit of cash on tools and services I don't really need, then ended up doing some of this stuff manually anyway just to learn. At which point my first site ranked. Now I automate all of it, but I had to do my time before I could get value out of my tools and pick the right services. Don't do what I did, do it right the first time.
