Some time ago, I raised a question about SEO charging standards. SEO charging is mainly based on the difficulty of SEO optimization. Generally, we judge the difficulty of SEO mainly based on the following points:
1. Baidu included volume (that is, "Found about xxxx relevant web pages" displayed in the upper right corner after Baidu searches for keywords)
2. Are all the websites that appear on the homepage have first-level domain names?
3. Whether the keywords are included in the title
4. Whether the keyword is in the first place in the title
5. How many promotions appear for this keyword?
6. PR status of rival websites
7. External links of rival websites
8. The form of the opponent’s website and the amount of information
There are many judgment factors.
How to calculate the formula: First, we set the difficulty of optimizing to the first place on the homepage to the ideal state (that is: without any competitor websites, as long as you have a website submitted to the search engine, you can rank first) and the ranking difficulty is zero.
We set a percentage value for each factor and opponent that hinders our ranking on the homepage according to the difficulty of ranking, and then add the values to get the difficulty coefficient. Then subtract the difficulty coefficient percentage from 1 (ie: 100%) to get the ranking success rate.
For example: We set the difficulty factor of a promoted website that prevents us from ranking on the home page to 10%. Then if 10 promotions appear on the home page, the difficulty factor of our ranking on the home page is 100%, and the success rate is 0, which means it is impossible to rank on the home page. !
