I have a question and since I don't know the answer it bothers me. I understand the importance of SEO in terms of ranking etc.
My question is while header tags (h1 ... h6) are important and should be used to illustrate important key words and terms, does inserting a <span> tag inside that header tag affect its effectiveness?
for example
Code:
<h1> <span class="boardit">Portfolio</span> </h1>
Is the span tag within header tag bad for my SEO work ?
