SEO is the process of improving traffic to a website by utilizing several proven SEO techniques which help a site achieve higher ranking in some of the major search engines. There are a wide range of SEO services that offer solutions for different ranking issues. Generally, the choice of service will depend on your needs and goals.
Types of SEO services
SEO content writing
One major service offered by SEO firms is SEO content writing and marketing. This term implies that there's a closely guarded writing formula used, which helps turn a simple plain text into something magical that actually gets noticed by search engines. When looking for a content writing service to help your site attain higher rankings, you are not looking for SEO content but rather well written, high quality content.
When used as a service, SEO content writing can be very useful especially if shortcuts aren't taken, and content written isn't expected to achieve something magical. Well written and useful content can be easy to find and attracts attention of many people searching the relevant keywords. It can also help lay the basis for your link development campaign.
Website SEO audit
SEO audits may vary in terms of detail or complexity. A comprehensive website audit may comprise of more than one hundred pages (especially for large websites) and will address each website element, however tiny it might be, which could possibly affect a website's ranking-ability. On the other hand, a simple website SEO audit can be comprised of 10 or fewer pages, and generally will address only the glaring on-page issues like lack of content or missing titles.
On-page SEO refers to techniques that are designed to implement the potential issues uncovered by an SEO audit. It addresses a wide range of fundamental elements (in the exact way the elements relate to SEO) like headings, titles, internal link structure, content and organization of content. Just like the website SEO audit, on-page SEO includes both basic and comprehensive services.
At the simplest level, an on-site optimization campaign may be a one-time task that includes the recommendations developed via an website audit, and implementation of the recommendations as well. This kind of optimization can generally target several important pages on a site including the home page. A comprehensive on-page SEO campaign would use the findings and recommendations of a detailed website audit, and closely monitor the results to guide any changes occurring to the optimization.
SEO service generally involves complete overhaul of a website HTML and is therefore regarded as one of the high level search engine optimization services. Optimization of your site HTML will likely impact the rankings in two main ways. First, it could help eliminate code-clutter and present the content in a more easy-to-understand format. Second, it could help significantly reduce the overall load-time of your site pages, and in turn search engine spiders won't have to wait for long while your pages load. Load-time usually depends on the number of images on the page and the length of the page among others.
