If it doesn´t negatively affect the search-engine, then I don´t care. I just believed, that in the keywords there had to be only commas. After filling the tags, the extra commas that I mentioned before, wanished, but there are still unwanted spaces after the keyword (for example toys ,). Is this ok?
And one more issue. I added the header tags seo code also to the conditios.php, shipping.php etc. pages. As I am located in Europe, I use no english version of the shop. So in conditions.php the title should be "Obchodne podmienky" (in slovak). But no matter what I do in the page control, there is allways just "Conditions" showing in the title (cleared the browser cache, ...). Do You have any ideas on this issue?
