The size of the website affects the price of SEO. If it is an extensive website and has strong competition that invest heavily in linkbuilding activities, the cost of SEO will be determined individually. In such a situation, you need to estimate how many months it will take to chase pages from the same industry with specific types of budget and what actions should be performed.
At the outset, the pages can be divided into those without an online store and those with online sales. In both cases, the scope of activities and the time of their performance are different. Therefore, the price of search engine optimisation will also differ - often the SEO cost of an online store is higher. Sites without a store, including:
they present local businesses (where it is impossible to use or buy a service / product) via the Internet, e.g. cafe, hairdresser;
are corporate image websites;
are the online version of the portfolio.
They have much fewer subpages, do not have product categories, and are distinguished by a less complicated structure. They can be static or dynamic and have blogs. Online stores, on the other hand, are more extensive. There are, of course, instances where SEO for your non-retail site will be expensive. These are the situations where the SEO cost in a given industry is high due to competition.
Significant website parameters that affect the price of search engine optimisation are also: domain age, CMS system, optimisation level, number of technical errors to be fixed, linking level (number of links, toxicity, quality), content (duplications, filling the website with content, use of phrases, headers).
