Does a tag inside H1 affect SEO?

[stepsstones]

We are using a tag inside our H1 tag to display a second line of text, usually for extra information and making the tag appeal like a intro text for the visitor and not just a optimized SEO tag.

Example: https://www.denhollandsche.nl/grafmonumenten/

Does this technique affect SEO? Should we consider removing it?

Just to expand on the other comments, the tag is used for styling, (http://www.w3schools.com/TAGs/tag_small.asp)

So the h1 would still apply, it is just styled different to the "standard" h1 style.

Hello,

Why using small, that smaller text inside tags ? You can replace this with a div or span with class "small "for example, and create the same effect with :

.small {font-size: smaller; }

Hi Martjin,

No it doesn't affect the SEO optimization.

Hope it helps.
