CONS of Do-It-Yourself SEO
Do-It-Yourself SEO can be time consuming. It won't be a basic hour long job and then you need not do anything further. SEO is an ongoing process that needs to be consistent. Just as any other job needs consistency, so does this one.
In many cases, you're not certain of how effective your SEO strategy might be. It's mostly a matter of do-evaluate-revise-redo, and that takes time to accomplish.
Hiring an SEO Company-The Pros
When you hire an SEO company, all of the work is done for you. All you have to do is cross it off of your list of things to do. It saves you time and energy that you can focus on making your business grow in other ways.
SEO is a very dynamic field. It changes constantly. Hiring an SEO team who know what to do, and are well apprised of the changes that have been taking place is one of the best ways to assure that you keep your rank and traffic.
You will quite likely get faster results when you get an SEO company to do your work. Due to the many different systems and software that they have in place, they will likely be able to automate some of the work that you are doing by hand. Your site will continue to grow each month as they implement a strategy that leads you to bigger profits for your business.
Just as in any other type of industry, SEO has a few bad eggs out there. They may take the kind of tactic or effort that can actually harm your SEO or your company, so you will want to do your homework very well when you check out the SEO company that you are considering. Never hire an SEO company out of hand without checking out their methods and their reputation in the business world. Look for real testimonials as well as examples of their work and do ask for references.
Whether you hire a company to do your SEO or you do your own SEO using the Do-It-Yourself method, SEO is one of the best ways to promote your business and to increase your bottom line.
