Technical optimization
In the process, SEO specialists look for all the flaws on the site that interfere with the indexing of pages by search bots, negatively affect the rankings or user experience.
Working out keywords and working with structure
This is one of the most voluminous aspects of work that is exclusively done by SEO specialists. The sense of the study of keywords is to expand the semantic core of the site and group queries into the most relevant groups. Thus, you can increase the number of search queries for which the resource appears in search results.
The larger the site, the more keys it can contain. This affects the time and cost of work, as it can take an optimizer several full working days to study and work through thousands of keywords.
Content creation
The cost of creating content is influenced by the skill level of copywriters, the complexity of the topic and the amount of text required. For example, if you just need to fill the page with unique text and add keys there, this work will be inexpensive. But such content is not highly regarded by users and search engines.
To create informative and useful text, you need to find an author who is an expert in your niche. But the cost of his services will be much higher.
Placement of materials on external sites
Placing content on other sites is one of the main ways to get backlinks. The price of such publications depends on the internal policy of the site where you plan to publish and the cost of the services of copywriters who write texts.
Analytics and improvements
Every month, optimizers analyse the effectiveness of website promotion: they collect data on the dynamics of changes in positions, traffic indicators, behavioural factors and conversion. The client receives this information in the form of a report, but the main task of collecting data is to analyse and adjust the promotion strategy.
This stage is just necessary to reduce the cost of promotion in the next month without reducing or increasing the effectiveness.
