Welcome to the Q&A Forum

I've been working on creating content and optimizing my website for the past 18 months, and have seen decent gains in organic traffic. Recently my keyword ranking increases have slowed dramatically, despite adding additional content. I'm hoping a fresh set of eyes can spot something that may be holding me back. I appreciate any feedback the MOZ community is able to provide. One area of concern/confusion is the number of pages indexed according to GSC. The number tends to go up and down, and I can't figure out why. Of the roughly 8,000 pages that are submitted through the sitemap, it says only around 1,100 are indexed (sitemap page). The index status page says I've got 7,500 pages indexed. Kind of confused on that one. Anyway, my website is MetroAtlantaHome dot com. Thanks everyone!

Lately I've noticed more and more 503/504 errors being flagged in my MOZ reports. One week I had over 1300 errors show up. I checked Google Webmaster Tools and Bing Webmaster tools and noticed they were showing up in there too, although not near as many (50 or less per day). I contacted my hosting company about it and they said these were normal and that it was due to one nameserver reaching capacity, but that there was a backup nameserver that kicks in. I've seen one or two of these errors show up before, but never more than one or two a week. Is this something I should be concerned about?

Do those of you using Bing Webmaster tools find your sitemap last crawl date gets updated? I noticed mine never updates, just shows the date of the last time I submitted it. It seems like it would update daily as it looks like bing crawls my site daily. See attached image. bing-screen-shot.png

I have some pages on my site that don't really have any content other than some iframes that are embedded from another site. I thought it would be best to tag the page with a no-index so that search engines would leave the page alone since it has no content as far as the search engine can tell (but does provide value to my site visitors). Is this the proper approach or does it do more harm than good?
