Question

Search Engine Optimization

The organization has a website that provides several different services. For example, the installation of video surveillance systems and the corresponding page on the site.
How good is it to look for an SEO studio or a freelancer who will SEO promote this particular page for 10,000 per month?

Answer 1

It is not enough to invest only money, there are many nuances. Optimization of the article for search engines, optimization of the site itself, what keywords you work on - are these low-frequency queries or high-frequency ones, etc. You can get the same result for 5 thousand as for 10. Everything depends on you or the marketer.

Answer 2

It is pointless to promote just one page on the site. Will not work.
If the page differs from the target direction of the site - it is doubly pointless. If you promote then only the main direction of the site. But here, without auditing your site, analyzing competitors and viewing search results, it is difficult to say something about the meaning of your undertaking.

Answer 3

if the niche is empty then top1
if there is competition like windows there then top100
