The SEOmoz crawl diagnostic tool is complaining that I'm missing a meta description tag from a file that is an RSS xml file. In my <channel>section I do have a <description>tag. Is this a bug in the SEOmoz tool or do I need to add another tag to satisify the warning?</description></channel>

Working on reducing page load time, since that is one of the ranking factors that Google uses. I've been using Page Speed FireFox plugin (requires FireBug), which is free. Pretty happy with it but wondering if others have pointers to good tools for this task. Thanks...

What is the best SEO page/link structure for a blog with, say 100 posts that grows at a rate of 4 per month? Each post is 500+ words with charts/graphics; they're not simple one paragraph postings. Rather than use a CMS I have a hand crafted HTML/CSS blog (for tighter integration with the parent site, some dynamic data effects, and in general to have total control). I have a sidebar with headlines from all prior posts, and my blog home page is a 1 line summary of each article. I feel that after 100 articles the sidebar and home page have too many links on them. What is the optimal way to split them up? They are all covering the same niche topic that my site is about. I thought of making the side bar and home page only have the most recent 25 postings, and then create an archive directory for older posts. But categorizing by time doesn't really help someone looking for a specific topic. I could tag each entry with 2-3 keywords and then make the sidebar a sorted list of tags. Clicking on a tag would then show an intermediate index of all articles that have that tag, and then you could click on an article title to read the whole article. Or is there some other strategy that is optimal for SEO and the indexing robots? Is it bad to have a blog that is too heirarchical (where articles are 3 levels down from the root domain) or too flat (if there are 100s of entries)? Thanks for any thoughts or pointers.

Two places capitalization comes into play: (1) on-page use (title, h1, body text, img alt text, etc) (2) external anchor text I didn't think it mattered from Google's point of view for on-page usage (is this correct?) but I notice that OpenSiteExplorer' s 'anchor text distribution' tab shows different counts for the same keyword if it's capitalized in different ways (eg seomoz.org is listed separate from SEOmoz.org). Is that just OSE or does Google treat the keyword/phrase different based on its capitalization, too? And if so, then should I be creating external links to my site with the 'regular' and 'Capitalized' versions of my key phrases?

After completing several months of on-page SEO for my site (one keyphrase per URL) and getting an "A" from SEOmoz on each page, now I'm venturing into PPC AdWords for the first time. From what I've read you pretty much want one landing page per keyword/ad. So if I want to target 100 PPC keywords I need 100 landing pages. And each landing page needs to be SEO'd as if you were doing it for organic search purposes so that your ad has a chance at a high Quality Score (8 to 10). I realize that an ad's QS is 2/3rds driven by its CTR but in the beginning when the ad is new the initial QS assigned seems to be driven more by landing page relevancy and some historical attributes of the AdWords account in which the ad or Campaign is located. My question is: What, if anything, do you do different on a page designed to be a PPC landing page as compared to a regular page you would SEO for organic search benefits? Also, should you do any of the off-page things (external links with relevant anchor text) for PPC landing pages? I'm envisioning landing pages that only exist to receive PPC ad clicks and that will not be linked to from my site directly. Each landing page talks a bit about the keyword the user was searching on and then directs them to the most relevant page(s) within my site. Maybe that's flawed? Thanks for any tips...
