Blog Directories: There are many blog directories out there like Blog Catalog or Blogged that showcase some of the best industry specific blogs in any industry. It is a great starting point to start with your research when you are trying to put together a blog commenting campaign.

Blog Rolls: Often times when you find a blog in your industry they might have a blog roll set up to show their audience other industry specific blogs that are relevant. I have come across some blogs that have been known to showcase almost every single important industry blog in their specific field in their blog roll really helping out my research efforts.

Blog Search: As simple as it might sound try just doing a search for your specific blogs in the search engines. See what you come up with. You might just find some of the best blogs to leave comments on directly in the search results. Try doing a web search and also look for keywords in your industry under the actual blog search attached to your favorite search engine. Most search engines will allow you to actually do a blog search right through the engine.

Blog Lists: Use the word “lists” in your search phrases to find others who might have put together a list of your top industry blogs already. Putting together a list of the best blogs in a certain industry can often times bring nice rankings along with traffic so someone in your industry will often times complete the grunt work to find the top industry blogs for you already.

Unless you are in a very tight niche you should be able to find some blogs in your industry where you can leave educated comments on. Just take the time and look around in order to find what you are looking for.

That’s very much a question that’s open to debate, depending on who you ask, you could expect to hear a whole range of answers. Networking has become ingrained in the Internet marketer’s psyche, building relationships while interacting with your fellow professionals and consumers. But can it really compete with building an impressive linking infrastructure when it comes to marketing your website online?

Let’s start with the positives…

Both techniques work in very different ways. You build links by making requests, payments (only to the right people – directories and the sort) and creating content that causes a stir. Networking can of course help this process. When you get noticed by more people, they may be inclined to link to you; there’s no certainty of course, but social media is a way of raising a profile and showing off your expertise to the world – prime link bait conditions.

There are easy ways to get links and hard ways. Even if you create a fantastic blog, a great new piece of shareware or a stunning design, there’s no assurance that people will find you. Quality links are often those that happen organically, the kind of thing that you can’t force. Article submission and press releases will assure you of at least one (sometimes more) link back to your site; while the every little bit helps strategy is a good one, that link can take time to gain and time is precious, particularly when the outcome doesn’t quite justify the means.

Of course the main reason most people create an article or release, at least in an SEO capacity, is to get it picked up and syndicated across a number of sites. The dream ticket is a major news agency picking up a story on their newswire and sending it global; this, of course, is extremely rare. For this to happen, it needs to be relevant, it needs to be interesting and it needs to provide something new. Regurgitating the same stuff over and over again may save time, but that could well prove to be a false economy.

But once again we’re thrust back into the realms of Web 2.0. If you want to get people talking about your content, you may first need to start shouting about it. Herein lies the weakness though of social media.

…Now for the negatives

There is still a cloud of mysticism that hangs over the social side of the Internet. Just how effective is it? If you have the time to dedicate to interact with the wider community day in day out, then the benefits can’t be argued. Normal people have become celebrities, while the celebrities themselves have been out there growing legions of new fans. All very positive. But what is the value of a follower or a friend? Commenting on blogs, reciprocating tweets and conversing offers a fantastic community spirit; allowing users worldwide to get involved in a continuous conversation.

What all this won’t do, necessarily, is improve your site and its strength. You might get traffic, in fact you will almost certainly get traffic, but if this comes from the same basic group of people, none of whom have the slightest interest in using your business or buying your products, is it really worth the investment of time? Friends and followers aren’t just an ego trip; it shows a level of influence and provides a wider sphere of influence. A strong linking strategy though goes further.

Every link you earn will join a wider group of inbound pointers. Google likes websites that people like pointing to. Therefore, Google likes nothing more than a site with links going to all pages, coming from a variety of sources and in a natural fashion. While there are dangerous links out there, toxic ones that will cause more damage than good, these can be avoided and banished if need be.

Whether it’s on a directory, bolted onto an article or has come from a respected source organically, the power of the link is hard to question. Aside from a permanent new gateway for targeted traffíc to find you, it adds vital strength to your website’s overall profile. PageRank maybe all but defunct, but that doesn’t mean that links are treading the same path.

We wouldn’t ever discourage people from using social media; it has fantastic potential and is evolving all the time. But if website promotion and search engine marketing is what you’re looking to do, the tried and trusted link may well prove a more constructive use of your time. It maybe a quieter way of going about things, anti-social even, but links get you seen on search engines and search engines get you seen by consumers.

Your online profile may ebb and flow, your popularity wane, but when you build a strong link profile you create stability and open the door to continued development. They are the foundation to any successful site; so while it’s always nice to have flighty friends, the stability and long-term benefit of a link is still very much the method of choice for most.

But how — and how much?

To answer these questions, I looked at data from 1,531 HubSpot customers (mostly small- and medium-sized businesses). 795 of the businesses in my sample blogged, 736 didn’t.
The data was crystal clear: Companies that blog have far better marketing results. Specifically, the average company that blogs has:

• 55% more visitors
• 97% more inbound links
• 434% more indexed pages

Take a look for yourself in the graphs below:

Why are website visitors important? Because more visitors mean more people to convert to leads and sales.

Why are inbound links important? Because they signal authority to search engines, thus increasing your chances of getting found in those search engines.
