Calculation of profitability of search promotion
Clause{Article} is intended for owners of sites, directors / managers on marketing and other persons responsible{crucial} for promotion of the goods and services.
In this clause{article} I have applied a principle « from the opposite ». That is, when there comes the "standard" offer on promotion of a site and already begin obgovarivat`sja the prices for promotion, whether that is the opportunity to count up « costs{stands} ovchinka manufactures ».
So, to you there comes the offer with guarantees and the preliminary prices for promotion of a site. Usually in him search searches on which the site should move ahead in search engines are specified. Also obgovarivajutsja places with which the site should borrow{occupy} in search engines, search engines. Discussion of the prices also begins.
At the moment at the majority of firms in market SEO of the price depend on number of searches which are necessary for advancing. And the final price for promotion which usually is called as three or four-unit number in US dollars a month, basically depends on number of search searches.
The available data for calculation of profitability:
1. The price. Obgovarivaetsja with representatives of the firm giving services SEO.
2. Search searches for promotion of a site. With all their frequencies in various search engines.
3. The current positions of a site on necessary search searches.
4. The future positions of a site on necessary search searches.
5. The current quantity{amount} of visitors on a site.
6. The current profit from a site.
In the beginning it is necessary to calculate the current search visibility of a site. Calculation of visibility of a site is made by a technique « the Rating of visibility of a site in search engines »
Pay attention, what in a technique, and in tools in which she is realized seo rate and site auditor are used average and teoritizirovannye values CTR of positions in SERP and distributions of shares of search engines, and they can appear rather far from a reality. Actually we consider the future attendance of a site.
For calculation CTR of positions in SERP it is possible to use the table « Distribution klikov and attention to page of delivery Google » from « Research of eye activity of users at university Cornell »
For calculation of distribution of weight of this or that search engine there are some techniques. In my opinion, the most exact - a trial advertising campaign. In result it is possible to count up precisely a parity{ratio} of each search engine practically for any search.
Using these figures - it is counted the future search visibility of a site. Pay attention, that if the SEO-firm guarantees to you TOP5 it is necessary to count average CTR from the first on the fifth places as, there will be what is the time a site on 5 place or on 1 anybody does not know.
In result we concern: (the future profit from a site) / ((the current search visibility) * (the general{common} frequency of searches) * (CTR positions)).
Knowing the current quantity{amount} of visitors on a site and the current profit from a site, we consider the future profit from a site.
Unfortunately dependence « from a site » from « attendance of a site » in open access no the profit. Quite probably, what is it complex{difficult} dependence. But as a first approximation it is possible to count, what is it dependence linear.
Further compare, how much you will receive in a month of the profit from a site with the monthly price for promotion and judge, whether it is necessary to reserve search promotion under such price.
