If you are in Australia you should hire an SEO company in Australia. While there is absolutely nothing stopping you from hiring an SEO company in Dubai, China, South Africa, anywhere who says they will do cheap SEO, we suggest you always get your marketing done by people who understand you, how your business works, what your business is, and who your target market could be. And nobody understands Australians better than Australians themselves. An Australian marketing or digital marketing company knows what kind of words will appeal to the Australian market, and what kind of copy will get a reaction. Also, all SEO costs the same so even if a company in say Mongolia is telling you they can do it for cheaper, they cannot. And they are very unlikely to get the same results that an Australian company will get.
The hidden costs of SEO
There are no hidden costs of SEO! When you employ an SEO company they will talk to you, learn about your product and your intended market, and they will come up with a marketing campaign. Before they put anything into action they will run everything by you, explain how it works, how they will start campaigns, how they will track campaigns, how they will analyse campaigns, and if a campaign is not working, how they will halt it and amend it. The most important thing in all of this is SEO. You will pay a digital agency or an SEO company to create a campaign for you, not expensive! They will create the content, the ads, the posts and more, using SEO. You pay, not for the SEO, but for the pay per clicks. If people click on and through your ad, you pay.
