Is it necessary to redirect every Error page (404 or 500) found?
-
If I have Hundreds of pages with 404 and 500 erros should set up 301 redirects for all of them? Some of the pages have external links, some don't.
-
There are a few reasons this can happen. Each tool crawls the web at different times and see different things. I would recommend at least investigating any issues you find regardless of which tool you used to discover it.
Personally, I would pay good money for a tool from Google which used their algorithms and data, but that isn't an option so we do the best we can with the available tools. Google WMT and SEOmoz crawl reports are two parts of that solution for me.

Josh- I'm of the opinion that there is no tool in the wild that is consistently accurate, in any regard, including detection of 404 errors. There are a number of things that can cause one tool to detect an error, while another won't. Personally, I compare the results of all the different tools I use, and hopefully find a consensus. Failing that, I double check with them all, and look for consistent results. If nothing changes, you may just have to "consider the source" and decide in which tool you have greater confidence.
Not much help, I realize, but sometimes that's just the way it is.

Thanks-
Some of the errors came from Opensiteexporer, but are not in Google webmaster tools. What do you think about this?
-
500 errors should not happen. I would recommend determining the root issue and resolving it.
404s are a natural part of the internet. There is nothing inherently wrong with your site having some pages that offer 404 errors.
With that said, I recommend taking any pages with value that 404 and 301 them to the most appropriate page on your site. It will allow your link juice to be retained, and offer your users a better experience.
I would also recommend offering a soft 404 error page that offers a site map or other navigation help.

Moving pages to new domain
Hello, Our product pages are ranked #1 on google for our target keywords using our domain e.g. www.olddomain.com/cases/productxyz and sell about 20 products all ranked #1. We have a new company called www.newco.com/case/product1, 2, 3 etc. We use woocommerce e-commerce for both old and new sites. What is the best way to list our old co-products on our new site and move over the #1 rankings? Do we create new products (using our new nice design) in the newco.com woo commerce and then redirect old co links? do we copy and paste all that old content into the newco.com? Totally confused. Thank you!

How to fix non-crawlable pages affected by CSS modals?
I stumbled across something new when doing a site audit in SEMRUSH today ---> Modals. The case: Several pages could not be crawled because of (modal:) in the URL. What I know: "A modal is a dialog box/popup window that is displayed on top of the current page" based on CSS and JS. What I don't know: How to prevent crawlers from finding them.

Is having a site map page necessary?
Hello all! So I know having a sitemap XML file is important to include in your robots.txt file. I also know it is important to submit your XML sitemap to Google and Bing. However, I am wondering if it is beneficial for your site's SEO value to have a sitemap page displayed on your website? Or is this just a redundant action if you have already done the above two actions with your XML sitemap? Thanks in advance!

Body of text on category pages
Hello everyone, wonder if I can pick your brains about our company's website. We are a tea company - Canton Tea Co. We have been advised that it is really important to get more text onto the category pages on our website, as otherwise the page just consists of a list of products, and therefore provides Google with a ton of headers, tiny descriptions, and not enough text to allow the page to being easily indexed, therefore hurting our Google ranking for key search terms like 'Green Tea' which should lead to the Green Tea category page. So we decided to add some text to the category page. The only place for this text to go was laid over the category header image. However, it looks pretty awful and unsophisticated having this text on top of the image - please see an example, our Green Tea category page, via this link: http://www.cantonteaco.com/loose-leaf-tea-1/type/green-tea.html So I have three questions: How significant is the text on a category page such as this to that page's Google ranking? If we moved the text to an area that was hidden until clicked on, for example the 'Filter by' section that opens up when you click on it (see via URL above), would that negate the SEO benefit? Do you have any other ideas or opinions on how to resolve this? Thank you! Louise, Canton Tea Co.

How long should an old site redirecting to a new site remain activated on a server?
Once I switch a site to a new domain (with links to corresponding/relative pages), will I have to keep the old site live forever for those links to work, or how long should I wait before I inactivate the old site on our server?

One Page Guide vs. Multiple Individual Pages
Howdy, Mozzers! I am having a battle with my inner-self regarding how to structure a resources section for our website. We're building out several pieces of content that are meant to be educational for our clients and I'm having trouble deciding how to layout the content structure. We could either layout all eight short sections on a single page, or create individual pages for each section. The goal is obviously to attract new potential clients by targeting these terms that they may be searching for in an information gathering stage. Here's my dilemma...
Web Design | | jpretz
With the single page guide, it would be nice because it will have a lot of content (and of course, keywords) to be picked up by the SERPS but I worry that it is going to be a bit crammed (because of eight sections) for the user. The individual pages would be much better organized and you can target more specific keywords, but I worry that it may get flagged for light content as some pages may have as little as a 150 word description. I have always been mindful of writing copy for searchers over spiders, but now I'm at a more technical crossroads as far as potentially getting dinged for not having robust content on each page. Here's where you come in...
What do you think is the better of the two options? I like the idea of having the multiple pages because of the ability to hone-in on a keyword and the clean, organized feel, but I worry about the lack of content (and possibly losing out on long-tail opportunities). I'd love to hear your thoughts. Please and thank you. Ready annnnnnnnnnnnd GO!0 -

Decreasing Page Load Time with Placeholder Images - Good Idea or Bad Idea?
In an effort to decease our page load time, we are looking at making a change so that all product images on any page past page 1 load with a place holder image. When the user clicks to the next page, it then loads all of the images for that page. Right now, all of the product divs are loaded into a Javascript array and loaded in chunks to the page display div. Product-heavy pages significantly increase load time as the browser loads all of the images from the product HTML before the Javascript can rewrite the display div with page-specific product HTML. In order to get around this, we are looking at loading the product HTML with a small placeholder image and then substituting the appropriate product image URLs when each page is output to the display div. From a user experience, this change will be seamless and they won't be able to tell the difference, plus they will benefit from a potentially a short wait on loading the images for the page in question. However, the source of the page will have all of the product images in a given category page all having the same image. How much of a negative impact will this have on SEO?
