The Benefits Of Blogging:
1) Search Engine Marketing.
Search engines love fresh content. If you make a point of updating your blog on a daily basis, many of the search engines will make a point of indexing your blog regularly. This means they'll be going through your blog and adding the content (including your links) to their database. Get others involved in your blog as followers and leaving comments, and the search engines will love you even more!
2) Build Your Credibility.
There's no better way to establish your own credibility than by contributing valuable content via your own blog. People want to deal with experts. Your own blog can help establish your status as an expert within your niche.
3) Manage Your Reputation.
Rumors abound online and there's no better way to manage your online reputation than by contributing your own valuable content and being "transparent" via your own blog.
4) Stand Out From Your Competitors.
The internet is a competitive medium; especially if you are an Affiliate Marketer. You need a way to differentiate yourself from your competitors. Having your own blog helps you rise above the wave of duplicate affiliate sites. Again... Search Engines LOVE original content. Give them what they're looking for.
5) Low Cost.
Setting up your own blog on a site like blogger.com is free. That's a hard price to beat; especially when you consider the benefits you can realize via search engine marketing, relationship management, and brand building.
6) Direct Communications.
As people follow your blog, they can get your updates very quickly by simply checking in to see your latest updates.
7) Building Your Lists.
If you are planning to use your blog as part of your sales and marketing channel, you'll want to be sure you have an autoresponder subscription form on the blog so that you can convert some of those visitors in to targeted prospects.
When you think about it, the real question regarding blogging isn't so much "should I?" but more about "What are you waiting for?"
Blogging can be fun. It doesn't take much time to update your content and the benefits to your reputation, brand recognition, visibility, and sales are hard to beat!
