Should I replace underscores in page file names with hyphens?
-
Many of the 1000s of pages at our Web store that were established several years ago but still relevant today have underscores separating words in page file names. For example: http://www.audiobooksonline.com/whats_new_compact_disc_audiobooks_audio_books.html
Should I replace the underscores with hyphens like this:
http://www.audiobooksonline.com/whats-new-compact-disc-audiobooks-audio-books.html
or should I duplicate pages with underscores using hyphens and have the older pages with underscores 304 re-directed to the new pages with hyphens?

No worries. And, I agree with you on the drawbacks. I know I've made changes like this before and caused more problems than I think I had in the first place

Shoot, I just realized I linked to the same video. Thumbs up for that.

Hi Larry,
Truth be told - I would leave them alone.
It's true that Google treats underscores differently than dashes - or at least they did as recently as 2011. In this Webmaster Video, Matt Cutts explains that underscores act as a "joiner" - joining the two words together.
http://www.youtube.com/watch?feature=player_embedded&v=AQcSFsQyct8
But he also states that it's a minor effect, that's it's not worth changing if you don't have to.
I happen to agree with Matt on this. Changing your urls and/or redirecting them usually doesn't cause much problems, but in certain cases it can have a negative effect on your SEO, resulting in a loss of traffic and rankings. We generally advise folks not to change your URLs unless you have to - and in this case you don't have to.
CAVEAT: The only situation I would actually advise you to make this change is if you were overhauling your website/CMS and had to change your URL structure anyway. In this situation it would make sense, and you would want to redirect the old URLs via 301 to the new structure.
Hope this helps! Best of luck with your SEO.

Check out the attached video.
If it were me, I would look at the link profile of the pages that could potentially change and, assuming I didn't find something that told me to just keep it as is, I'd make the change and then 301 all of the underscored URLs to the rewritten URLs.

How to rank a product page
Hello, I have a product page and just did a little introduction ( 5 lines of text) but I have the feeling this is not enough for google. What is the solution ? Is it to increase the amount of content even though it is not going to be user friendly ? Or will google look at the product page I link too and take into account the content on those subpages to boost my "pillar / product page". Thank you,

May integrating my main category page in the index page improve my ranking of main category keyword?
90% of our sales are made with products in one of our product categories.
Intermediate & Advanced SEO | | lcourse
A search for main category keyword returns our root domain index page in google, not the category page.
I was wondering whether integrating the complete main category directly in the index page of the root domain and this way including much more relevant content for this main category keyword may have a positive impact on our google ranking for the main category keyword. Any thoughts?1 -
Redirecting 404 pages
Hello,We have a wordpress site that has some "hidden" pages with weird URL's. Due to the way the site was built (not by us) if we setup our standard practice for 404 pages some site functionality will be lost.Standard Practice for 404's www.domain.com/fafsaf shows 404 error pageProposed solution:- www.domain.com/safaf >forwards to> www.domain.com/404 - shows 404 error page. Will this stop the search engines indexing the pages? - we have also amended the robots.txt to try and stop some pages being indexed but we still keep finding the odd little "hidden" page.The aim is to try and get all the search engines just to index the few simple pages on the sitemap instead of finding all these extra pages.

What do you do with the page of a product that has been deleted?
As anyone know with an ecommerce website, products are constantly being added and removed. Once products are removed, the corresponding product pages are not reachable. Currently, I am redirecting to the Search page, if a product page is reached, whose corresponding product has been deleted. I am not sure if that is the correct, recommended technique from a SEO perspective. Should I try to show related products on the redirected page? Does anyone here know what is the best thing to do with this product page?

Can a home page penalty cause a drop in rankings for all pages?
All my main keywords have dropped out of the SERPS. Could it be that the home page (the strongest) page has been devalued and therefore 'link juice' that used to spread throughout the site is no longer doing so. Would this cause all other pages to drop? I just can't understand how all my pages have lost rankings. The site is still indexed so there's no problem there.

Pages with Little Content
I have a website that lists events in Dublin, Ireland. I want to provide a comprehensive number of listings but there are not enough hours in the day to provide a detailed (or even short) unique description for every event. At the moment I have some pages with little detail other than the event title and venue. Should I try and prevent Google from crawling/indexing these pages for fear of reducing the overall ranking of the site? At the moment I only link to these pages via the RSS feed. I could remove the pages entirely from my feed, but then that mean I remove information that might be useful to people following the events feed. Here is an example page with very little content

All page files in root? Or to use directories?
We have thousands of pages on our website; news articles, forum topics, download pages... etc - and at present they all reside in the root of the domain /. For example: /aosta-valley-i6816.html
Intermediate & Advanced SEO | | Peter264
/flight-sim-concorde-d1101.html
/what-is-best-addon-t3360.html We are considering moving over to a new URL system where we use directories. For example, the above URLs would be the following: /images/aosta-valley-i6816.html
/downloads/flight-sim-concorde-d1101.html
/forums/what-is-best-addon-t3360.html Would we have any benefit in using directories for SEO purposes? Would our current system perhaps mean too many files in the root / flagging as spammy? Would it be even better to use the following system which removes file endings completely and suggests each page is a directory: /images/aosta-valley/6816/
/downloads/flight-sim-concorde/1101/
/forums/what-is-best-addon/3360/ If so, what would be better: /images/aosta-valley/6816/ or /images/6816/aosta-valley/ Just looking for some clarity to our problem! Thank you for your help guys!0 -
Static index page or not?
Are there any advantages of dis-advantages to running a static homepage as opposed to a blog style homepage. I have be running a static page on my site with the latest posts displayed as links after the homepage content. I would like to remove the static page and move to a more visually appealing homepage that includes graphics for each post and the posts droppping down the page like normal blogs do. How will this effect my site if I move from a static page to a more dynamic blog style page layout? Could I still hold the spot I currently rank for with the optimized index content if I turn to a more traditional blog format? cheers,
