Hello, I am fairly new to SEO and have noticed issue with "WordPress SEO" in relation to the sitemap, specifically with images.
I've noticed in Webmaster tools, that of the 39 images found by the plugin, only 1 is listed as being indexed.
Previously, I used a image xml sitemap generator, in conjunction with this plugin's xml feature, to get the images indexed. I noticed that this second image sitemap destroyed the neat hierarchical search results as when using the xml feature from this plugin alone.
So my options would be to either add the previous image xml sitemap and destroy the hierarchical search results, and live with that. Or, does anyone suggest that I open up the Yoast sitemap file, and edit in the correct images I want to displayed for indexing?
I think part of the problem is that I use the "Multiple Post Thumbnails" plugin for my website. The featured image does not actually display on the pages with images. I have the featured image set to show as thumbnails in an archive, and a second "Featured Image", named differently, to output images to that page.
So what do the gurus recommend? Is it difficult, worth it to edit the sitemap xml by hand? I suppose I would disable the feature, edit it, reupload. Then when I create new pages, I would need to save the xml sitemap somewhere, turn on the xml sitemap feature to get an updated sitemap. Then copy-past, and modify it once more. Is it worth it? I have never edited an xml sitemap by hand, and it seems tedious to do for each time a new page is made...
Any other thoughts?
