Google Ads keyword suggestion

Google Ads is an advertising platform through which you can pay to advertise on Google. However, within this platform you can use a free “Keyword Suggestion” tool which is great.

This way you can easily see what words you could use and you can also see their searchability.

A similar service is also provided by Seznam’s Sklik advertising platform.

Sklik keyword suggestion

A detailed description of how to use Sklik to suggest keywords can be found inOfficial Help List. However, this is a fairly intuitive procedure, which I have written about here on the blog in the past.

So I highly recommend including the Sklik word suggestion option in your SEO routine.

The premium version ranks among the more expensive ones at 649 CZK / month.

However, it also offersfree version for one project, for which they will give you 1000 credits/month.

So I would definitely use this tool when analyzing keywords.

Ahrefs website authority checker

Ahfrefs website authority checker tells you how much authority the domain has. Note that this is not the same metric as, say, Page Authority from MOZ. Ahrefs has a metric of its own that you should only compare “against”.

Technical SEO
