Why is there such a big discrepancy between OSE and GWT regarding # backlinks?
-
Hello,
We have been doing some analysis around our backlink profiles for our sites and have been experiencing a massive discrepancy between what is reported as number of C class linking domains in OSE and the information returned in Google Webmaster tools.
For a variety of sites OSE is reporting numbers < 10 for C class linking doamins while GWT shows >100 unique domains linking (we confirmed that the majority of these links are in different C classes)
Is this simply a matter of the limited index size of OSE or could there be another explanation? It is interesting that the links that do show up in OSE a nearly exclusively sites that we own.

The OSE index is smaller than what Google reports in GWT, but then again, the links reported in GTW are famously inaccurate and often not up to date. Google often includes "junk" links that have very little chance of effecting their ranking algorithm.
Linkscape crawls approximately the top 25% of web, which is where the majority of links are found that actually influence rankings. It's not a perfect system, and sometimes links are missed, but it works well as a predictive tool and also for competitive research.
"It is interesting that the links that do show up in OSE a nearly exclusively sites that we own."
Yes, it is interesting. The links Linkscape miss tend to be either beneath layers of navigation, or on pages with few inbound links. Sometimes improving your link structure will help your links both appear in Linkscape, and improve crawling and rankings from Google as well (although I'd be careful in your case, because you own the sites in question, not to create the appearance of a link scheme)
Best of Luck!

Neither OSE and WMT is providing the real and full link profile. I have the same issue with several accounts.
But both can be a really good indicator if used together. Personally I use a 3 combo: WMT, OSE and the Majestic tool.
With those 3 powers combined (like in Captain Planet) you will have a really good feedback.
I use WMT as a primary tool when I have access and OSE and Majestic as second tier. I use OSE as the main tool for competition analysis and majestic as a backup - filling some gaps.
You can also try Raven for some additional feedback - but a agin, no tool will provide full100% accurate information.
Hope it helps.

Backlink inconsistency
Hello! We were ranked on page 1 in Google for the past 10 years for a specific key phase until this February when we were pushed to page 2. When analyzing backlinks via majestic.com we found that our backlinks haven't been consistent, we typically have around 1,000 or less, but in February they dropped, then began spiking inconsistently (from 3000+ to a few hundred, then back up). Not sure how accurate Majestic's reporting is but we've also noticed some sites which are spamming our site with links on their low-quality and porn content websites. Is this type of backlink inconsistency normal, or is this something that could be negatively impacting our rankings? UttesqA

GWT giving me 404 errors based on old and deleted site map
I'm getting a bunch of 404 crawl errors in my Google Webmaster Tools because we just moved our site to a new platform with new URL structure. We 301 redirected all the relevant pages. We submitted a new site map and then deleted all the site maps to the old website url structure. However, google keeps crawling the OLD urls and reporting back the 404 errors. It says that the website is linking to these 404 pages via an old outdated sitemap (which if you goto shows a 404 as well, so it's not as if Google is reading these old site maps now). Instead it's as if Google has cached the old sitemap but continues to use it to crawl these non-existent pages. Any thoughts?

Backlinks from unindexed pages - disavow ?
Hi I was analyzing my sites's backlinks and see a lot of the domains are not indexed by google.
Technical SEO | | VaiSam
I assume google has unindexed them - may be these domains are penalized. Should I request removal of my site's link from these pages ? What is the recommended approach in such a case? Thank you for your inputs.0 -
GWT Duplicate Content and Canonical Tag - Annoying
Hello everyone! I run an e-commerce site and I had some problems with duplicate meta descriptions for product pages. I implemented the rel=canonical in order to address this problem, but after more than a week the number of errors showing in google webmaster tools hasn't changed and the site has been crawled already three times since I put the rel canonical. I didn't change any description as each error regards a set of pages that are identical, same products, same descriptions just different length/colour. I am pretty sure the rel=canonical has been implemented correctly so I can't understand why I still have these errors coming up. Any suggestions? Cheers

Portfolio website: reciprocal backlinks and redirects
My company specializes in website design and development, and as such, the portfolio section on our website has lots of links to websites we've built. Generally, the way that we do this is that our portfolio sections links to URLs with a naming scheme as follows: http://ourcompany.com/client1 which is either a redirect to http://client1.com if the site is still up, or a version hosted on our website (http://ourcompany.com/client1) if the client is no longer hosting their site. In addition, most of our client sites contain a reciprocal link back to ourcompany.com, usually with the text "Website design and development by OurCompany". I have two questions about this arrangement: Might the reciprocal backlinks from the client sites be affecting the SEO results for ourcompany.com? I know that reciprocal backlinks can be occasionally problematic. If I do a search for "site:ourcompany.com", I'll get results for all of the client sites that we're hosting at http://ourcompany.com/client1, because I haven't excluded them in robots.txt. Of course, the content of these sites has little to do with that of our company, because we have a diverse array of clients and none of them do web design and development (which is the content focus of our site). Might this seemingly unrelated content be affecting our results? Should the client sites be excluded in robots.txt or via nofollow? Thanks very much!

Quick Seo question regarding 301 redirect
Hi everyone and thank you for showing interested in my problem and for helping me out with this easy thing i have going on
Technical SEO | | caw_roHere is how it puts out : I have 2 websites, same niche, mostly same keywords. Site #1 holding strong on google #2 ranking for months now. Site #2 was holding strong in google top 10 rankings until 2 weeks ago when it got sandboxed for some reason I want to use a 301 permanent redirect from Site #2 to Site #1 to pass all the link juice onto Site #1 and hopefully beat the #1 spot
The question: Will this affect Site #1 is anyway, considering Site #2 is in somehow sandbox ( i assume that, since he dropped more then 70 positions over night ) Is thins a good think to do or i risk damaging Site #1 by doing this ? Thanks allot in advance. Best regards,
Trinca Alexandru0
