SEO services are different from online marketing services in a few ways. First of all, SEO service is a marketing group in your organization rather than a one-time service. So while an online marketing company would offer on-site optimization for your website, an SEO company would offer a marketing group to grow your online presence. Secondly, SEO services typically will offer ongoing link-building services. So while an online marketing company would offer to submit your site to thousands of search engines, an SEO company will give you a marketing group to submit your site to a number of search engines or directories. What Are Off-Page SEO Services? Off-page SEO services are search engine optimization services that happen off the website. Now, this may include article submissions, press releases, blogs, and link building. However, there are a few important differences in these types of services. First of all, articles submissions in the off-page SEO services will be done by paid professional freelancers that are usually based in the respective country they are offered. A blog is done by you in the comfort of your own home, with little setup and no fees. And link building is done in the context of forums, web 2.0 properties, social media, and various other online properties. So this includes social bookmarking, blog commenting, blog directory submission, video posting, and others. What Are Paid SEO Services? Fee-based SEO services include SEM, Pay per click, and other SEM services. This is the most important difference between paid and unpaid SEO services. And these SEM services are usually offered to clients that have a target audience defined in the context of the SEO contract. And this involves making inferences for an audience based on their past search, their website, and their content. So it is done on the basis of keywords and on the basis of past performance in certain search engines. And these SEM services typically would cost a client between 2-5 dollars. And this includes not just paying an SEO professional but also buying the services of research firms, web analytics tools, and pay-per-click ad programs that are needed to carry out your paid search campaign. These services differ in their delivery, which also leads to a number of advantages. For example, SEM would usually lead to website design recommendations, website optimization, as well as link building and PPC campaign recommendations. And this includes a number of recommendations on which to base your campaign, and some recommendations in case your budget allows. So these services are an integral part of any SEO effort and are more essential than SEO consulting. And they can be considered as “off-page” SEO services. And these are part of the core SEO services that all other services build on. If you are looking for high ROI SEM and other services, you should consider SEO consulting. But it would require much more of your money and it is not always necessary. But it is not so cheap that it would not hurt your budget. Consultants are highly experienced and they know what they are doing. And they are experienced enough to know that they will not get much from you.
