You should not delete index.html.

This page is in fact the page that is shown initially - even if the page name is not shown in the browsers URL.

If only a domain is specified in the URL then the browser automatic looks if there is an index.html and then this is shown. This is why you can have a "nice" URL shown on papers and so.

Ok so I shoud keep the index page name ticked or unticked?

I have somebody worked on my seo and they are asking 

Existing Hyper Linking: Top NavigationHome https://www.countryandcoast.co.uk/index.html

• Recommended Hyper Linking: Top NavigationHome https://www.countryandcoast.co.uk/

What do you reccommend doing?

Thanks,

Andrew

What do you mean by ticked or unticked?

If you mean this    then it should not be changed for the home-page.

yes this box, at the moment it is unticked

should i leave it unticked?

thanks

For the home page (index) it should be unticked.

If you want to change names for other pages then you could do that - but keep the name short. Generally it is not needed to change names, so generally you could let the field be unchecked/unticked for your other pages too.

... copy this string:
<link rel = "canonical" href = "https://www.countryandcoast.co.uk/index.html" />
... and paste in this section:
>> Step 3 - Map > The Page Properties window INDEX/HOME > ▪Expert | ▪Custom Code: > 2^option > After opening the HEAD tag

A lot of things can be done by using custom code. If you really need this then do as KolAsim show. If it is not that important then I really think it is better to have a "clean" solution.

If you are familiar with custom code then it might be OK - if not - then only use custom code if you really want a special behaviour for your site.

thanks for the help. I am trying to do this because the guy working on my seo says not to have any duplicate pages and to have build the site around https://countryandcoast.co.uk
