There are so many factors that determine where your webpages appear on a Google search engine results page (SERP).
Here are a number of factors we know have a position impact where your site appears on Google.

• Quality backlinks from high ranking or authority websites
• The number of clicks to the page
• The quality of the content
• Is the site responsive
• Does the site support HTTPS

But, lets have a look at some seo factors that are overestimated.

1. Domain age.
According to Google, age does not matter.  If you have a site that is only a few years old and it is already being recognised for great content, that site will always rank above a site that is 10 years old and has little new or relevant content.
Of course if neither site has content worth showing, the older one may appear about the newer one, albeit well down the ranks away from page one.

2. Likes and shares.
We all know that you can purchase likes for any platform from service provides such as Fiverr.  Should you buy them ?  Probably not.
Unless people who shared the link demonstrate some related click-through-activity, Google will ignore it an may even penalise your site.

3. Bounce rate.
In the past this has been considered a very influencial factor, but it seems Google has matured and altered how it works with this measurement.  For example, if the visitor found exactly what they needed right way (phone number, answer to a question) why should they be penalised.
Instead, Google pays attention to what the visitor does next.  Do they continue searches (in which point Google might feel that you didn’t provide answers)

4. Shared hosting.
Shared hosting is cheap and most of the time it’s reliable.  Google doesn’t care if you used shared services or if host your site on a dedicated, cloud or virutal server.  The only time this might be a factor is if the shared server is extremely slow, or if a site on the shared server has a bad reputation (spam) and is dragging the rest of the sites down by association.

5.  H1 tags?
There is a perception that by putting titles inside an H2 rather than an H1, Google will consider it a little less important.  This isn’t true.  Google looks at the top and the page and works it’s way down.  It will assume a heading at the top which is bigger and bolder than the rest of the text is the main heading and rank accordingly.
