Confused about rel="canonical"
-
I'm receiving a duplicate content error in my reports for www.example.com and www.example.com/index.htm. Should I put the rel="canonical" on the index page and point it to www.example.com? And if I have other important pages where rel="canonical" is being suggested do I place the rel="canonical" on that page? For example if www.example/product is an important page would I place on that page?

I haven't considered this option, thanks for the tip.

I've read that a 301 redirect hurts your page rank. Is that true? Thanks for pointing me to that page. I've seen and read that page a long time ago and at the time it was like a foreign language. Now it makes more sense.

I dunno that Google gives you a good example of why you would use it, just where. Canonical, for all intents ard purposes, lets you pick which of your duplicates gets indexed.
Here's a real world example. Newegg.com has, literally, tens of thousands of products. Their site is in site.com/?id=STRING but they do a lot of URL based tracking. As such, you have a lot of site.com/?id=STRING&ref=1234 Now, Google will see all of those extra query string pages as unique pages with duplicate content. Newegg uses canonical to ensure that Google ignores all but the core product page.
So, why use a 301 and why use canonical? A 301 removes the page from the index. Canonical leaves the page indexed but transfers PR to the "real" page and helps avoid duplicate content.

To expand on what Petra said, have you considered using your .htaccess file to permanently redirect all version of your home page to www.example.com (and other pages as well)? This can be done in conjunction with rel="canonical".
SEOmoz offers a Redirection Best Practices doc that can help you out.

To your first question:
www.example.com/index.html --> use a 301 redirect to www.example.comRegarding rel canonical --> there the usage is explained pretty well:

Pages being flagged in Search Console as having a "no-index" tag, do not have a meta robots tag??
Hi, I am running a technical audit on a site which is causing me a few issues. The site is small and awkwardly built using lots of JS, animations and dynamic URL extensions (bit of a nightmare). I can see that it has only 5 pages being indexed in Google despite having over 25 pages submitted to Google via the sitemap in Search Console. The beta Search Console is telling me that there are 23 Urls marked with a 'noindex' tag, however when i go to view the page source and check the code of these pages, there are no meta robots tags at all - I have also checked the robots.txt file. Also, both Screaming Frog and Deep Crawl tools are failing to pick up these urls so i am a bit of a loss about how to find out whats going on. Inevitably i believe the creative agency who built the site had no idea about general website best practice, and that the dynamic url extensions may have something to do with the no-indexing. Any advice on this would be really appreciated. Are there any other ways of no-indexing pages which the dev / creative team might have implemented by accident? - What am i missing here? Thanks,

We have 302 redirect links on our forum that point to individual posts. Should we add a rel="nofollow" to these links?
Moz is showing us that we have a HUGE amount of 302 redirects. These are coming from our community forum. Forum URL: https://www.foodbloggerpro.com/community/ Example thread URL: https://www.foodbloggerpro.com/community/viewthread/322/ Example URL that points to a specific reply: https://www.foodbloggerpro.com/community/viewreply/1582/ The above link 302 redirects to this URL: https://www.foodbloggerpro.com/community/viewthread/322/#1582 My two questions would be: Do you think we should we add rel=nofollow to the specific reply URLs? If possible, should we make those redirects 301 vs. 302? Screencast attached. nofollow_302.mp4

"Search Box Optimization"
A client of ours recently received en email from a random SEO "company" claiming they could increase website traffic using a technique known as "search box optimization". Essentially, they are claiming they can insert a company name into the autocomplete results on Google. Clearly, this isn't a legitimate service - however, is it a well known technique? Despite our recommendation to not move forward with it, the client is still very intrigued. Here is a video of a similar service:

Help with pages Google is labeling "Not Followed"
I am seeing a number of pages that I am doing 301 redirects on coming up under the "Not Followed" category of the advanced index status in google webmasters. Google says this might be because the page is still showing active content or the redirect is not correct. I don't know how to tell if the page is still showing active content, and if someone can please tell me how to determine this it would be greatly appreciated. Also if you can provide a solution for how to adjust my page to make sure that the content is not appearing to be active, that would be amazing. Thanks in advance, here is a few links to pages that are experiencing this: www.luxuryhomehunt.com/homes-for-sale/sunnyisles.html www.luxuryhomehunt.com/homes-for-sale/summerield.html

Would this be considered "thin content?"
I share a lot of images via twitter and over the last year I've used several different tools to do this; mainly twitpic, and now instagram. Last year I wanted to try to find a way to host those images on my site so I could get the viewers of the picture back to my site instead a 3rd party (twitpic, etc.) I found a few plugins that worked "sort of" well, and so I used that for a while. (I have since stopped doing that in favor of using instagram.) But my question is do all of these image posts hurt my site you think? I had all of these images under a category called "twitter" but have since moved them to an uncategorized category until I figure out what I want to do with them. I wanted to see if anyone could chime in and give me some advice. Since the posts are just images with no content (other than the image) and the title isn't really "optimized" for anything do these posts do me more harm than good. Do I delete them all? Leave them as is? Or do something else? Also in hindsight I'm assuming this was a bad idea since the bounce rate for people clicking on a link just to see an image was probably very high, and may have caused the opposite result of what I was looking for. If I knew than what I know now I would have tracked the bounce rate of those links, how many people who viewed one of those images actually went to another page on the site, etc. But hindsight's 20/20. 🙂
