How to gain 10000 links in a week
Some time ago I visited a blog or article on some website where the author mentioned very easy way of gaining 10000 or 20000 or virtually unlimited number of links in a short time. The principle was this: Find as many blogs with the top commentators plugin installed as possible and comment. Keep commenting these blogs, but don’t spam. And you’ll get these links. So… I tried this method as it is really easy and simple. The only thing that may be frustrating is spending time. Because if you’re going to write 100 or 200 comments on blogs, not only you need experience in the topics which are blogs devoted to, but also you need plenty of time. The top commentators plugin makes it possible to get a free site-wide link if you make it to the topX (X is some number, I suppose bloggers can control this) commentators. So 10000 links can be achieved this way: Suppose that every blog with the top commentators plugin contains 200 pages in average. Then being one of the top commentators on 50 blogs will naturally bring you 10000 links. Easy… But there are, as usual, advantages and disadvantages too.
Advantages
1) It is easy to find such blogs. Just try this in Google : “top commentators” “powered by wordpress”.
2) Many bloggers also approve comments such as “Good article” or “Good information” (read below why this is also one of disadvantages).
3) These blogs (see point 1 above) are already indexed in Google, and the closer to the top10 they’re, the higher importance they carry. Practically speaking; Google likes them and so will your link.
4) Many bloggers talk about similar problems, so commenting one’s post can be useful when commenting second one’s post as one idea can be related/similar to the previous one.
Disadvantages
1) Blogs where the webmaster approves comments such as “Good article” or similar spammy comments are very easy targets for spammers. In the end, if you get into the topX of top commentators, any better spammer can kick you out of this list and replace you. Spam comments aren’t worth it.
2) Even 10000 links, but each 200 from one IP address, mean that their weight is lower than 10000 links where each come from different IP address.
3) It’s time consuming.
4) Many bloggers delete the top commentators list once per month, so a site-wide link today can be gone tomorrow.
5) Many (really many) bloggers use broken plugins or their WordPress installations are broken, and thus the comment form could work incorrectly (detecting you as spammer, or disallowing you to post any comment). In such a case you spend 5-10 minutes writing really good comment and after this you will get a blank screen after submitting the comment.
Now some real example… I tried this technique and spent about 2-3 days (each day maybe 5 hours of posting comments) on it. In the end, and after two updates of links in Google Webmaster Tools I noticed quite a good increase of external links that point to one of my sites; By about 2000 new links. Am not sure about how Google liked it, but definitely it seems to me that Yahoo likes these new links. Traffic from Yahoo has increased by 100%. From about 200 daily visits coming from Yahoo to about 400 daily visits.
Even though this is a completely legal SEO technique, still some bloggers will reject your comments and also bear in mind that not one, but hundreds or thousands of blogs may be dead.

Completely agree with this.
I stumbled across this by accident after I commented on a number of excellent posts I had recently read.
Around a week later a noticed a sharp increase in visits to my site and after further investigation realised that they had been generated by these comments.
Think I best get commenting…

I am using the Cross-Linker plugin and am wondering the following; I’m using it for seo linking purposes however since the link doesn’t exist until the post is viewed, would it really count as being a link to the search engines?
