I'm using SEOChecker 2.9.0 on Umbraco 8.2.0. It looks like SEOChecker doesn't take the culture into account when validating a page. This causes a variety of issues:

• When validating a page with multiple language variants SEOChecker has trouble fetching the focus keyword. It shows an error for each culture even though the focus keyword has been set (see screenshot).
• If the SEO description is set for one language variant but not for another, SEOChecker shows an error (see screenshot).
• SEOChecker does not show any positive validation results at all (green boxes).
• When executing a manual validation through the 'Validate pages' feature in the dashboard you can only set a start location, but not a culture. The validation issues per page are grouped into a single result and not separated per language variant. So if /nl/example/ validates correctly and /en/example/ has validation errors, the 'Validation issues' screen shows /nl/example/ as having validation issues (probably because it's the default language), not /en/example/.
