Search engines want websites to have natural links built slowly over time. While it is fairly easy to manipulate links on a web page to try to achieve a higher ranking, it is a lot harder to influence a search engine with external backlinks from other websites. This is also a reason why backlinks factor in so highly into a search engine’s algorithm. Lately, however, a search engine’s criteria for quality inbound links has gotten even tougher, thanks to unscrupulous webmasters trying to achieve these inbound links by deceptive or sneaky techniques, such as with hidden links, or automatically generated pages whose sole purpose is to provide inbound links to websites. These pages are called link farms, and they are not only disregarded by search engines, but linking to a link farm could get your site banned entirely.
Why backlinks is so important, and why must you build quality backlinks. A search engine considers the content of the sites to determine the QUALITY of a link. When inbound links to your site come from other sites, and those sites have content related to your site, these inbound links are considered more relevant to your site. If inbound links are found on sites with unrelated content, they are considered less relevant. The higher the relevance of inbound links, the greater their quality.
It is not enough just to have a large number of inbound links pointing to your site. Rather, you need to have a large number of QUALITY inbound links. This tool searches for websites that have a related theme to your website which are likely to add your link to their website. You specify a particular keyword or keyword phrase, and then the tool seeks out related sites for you. This helps to simplify your backlink building efforts by helping you create quality, relevant backlinks to your site, and making the job easier in the process.
There is another way to gain quality backlinks to your site, in addition to related site themes: anchor text. When a link incorporates a keyword into the text of the hyperlink, we call this quality anchor text. A link’s anchor text may be one of the under-estimated resources a webmaster has. Instead of using words like “click here” which probably won’t relate in any way to your website, using the words “Please visit our tips page for how to nurse an orphaned kitten” is a far better way to utilize a hyperlink.
Building Quality backlinks is one of the most important factors in Search Engine Optimization.
It is not enough just to have a lot of backlinks, it is the Quality of backlinks along with the Quantity that help you rank better in Search Engines.

Like most everyone already said, it’s maybe not the best idea. Keep in mind, not only will Google see that the blogs are from the same IP address, but if the content is the same you will get flagged and penalized for having duplicate content.

Remember, the best way to build an internet presence for your business, it to have legitimate unique content on your website. Also, having other websites link back to yours is helpful as well. Content and backlinks are the two biggest factors in determining rankings.

Now, there’s tons of different methodologies about SEO so it’s really a matter of examining your business model and figuring out which one will be the most effective for you!

I hope this helps!
