Welcome to the Q&A Forum

I'm working on a site that has a jquery image rotation. Wondering if how the developer set it up is consider blackhat or spammy at all. The jquery has 3 images that rotate. Each image has text in it - which is then placed in a H1 or H2 tag behind the images. When viewing the site with images and javascript turned off it looks like the text is the same color as the background and not lined up nicely so that it is visible to anyone who has images and javascript turned off. Let me know if this is a bad practice. If so, what is the best practice to handle this? If the text were another color and aligned neatly visible behind the image would it be safe? Should we just be using an image alt tag instead? What about losing the H1, H2 power then? Any other suggestions for improving the SEO for jquery image rotations where important text appears? I can PM the site URL if you want to take a look. Thanks in advance!

We have a client whose site is fairly new. There isn't much in the way of SEO results so far. In their content management system they have implemented friendly URLs and changed the extensions from aspx to htm. Now the htm pages are all indexed in Google but when I run a campaign report in SEOmoz it shows that all pages are duplicated with there being both htm and aspx pages for each page. Should we do 301 redirects from the aspx pages to the htm pages? Or would we be safe by removing the htm pages and letting Google reindex the site with the aspx page extensions? Does Google have any kind of preference as to what the page extensions are as long as the  URLs include keywords?
