@shayanaman All links on here are nofollow so have no SEO value. You are wasting your time, go and spam another forum!

Outbound links are very important, just be careful to use them in context, if you are you are only using logo/image make sure to use alt text on the image.

@citimarinemoz Properly the bigger question is what do you mean by re purposing the blog.
If you are keeping the context of the blog the same, providing it is the same domain, the content is the same or better and you do your 301s properly it should be fine.
On the other hand if you are changing what your blog focuses on and you are rewriting the content of the pages you could well run into a problem.
My advice would be

1. Keep the same domain
2. Keep the old blog posts if possible, maybe update them if necessary
3. Create new blog posts with your new content on the same domain
4. Utilise internal linking for any relevant topics and pages

It shouldn't have any effect on SEO but it may cause a usability issue, if people can't find what they want some search engines can detect that could have an indirect effect on SEO

Providing you've got a separator (like a hyphen) it shouldn't make any difference. I will be more concerned about the grammar and how it looks to the searcher.
If it was me and I was using it to separate two different phrases I would make sure it had spaces either side. However, if it's a hyphenated word it wouldn't make sense to use spaces.

There is a slight misconception here, DA is not a Google metric. It is a MOZ metric (and a very useful one) Google no longer publishes their authority score.

As things are currently secure webpages are not a make or break. Google says that if you are collecting people's information, payment information or other sensitive data you should use a secure page.  However, if you are just telling somebody how to reinstall Windows 10 it's probably not a big deal.

It will probably become more of an issue as time goes on, but currently there are still a number of online shops which are not secure and they rank reasonably well.

That said, where ever possible always use SSL (or to give it its official name TLS).

The easiest way is to do it is from WordPress itself, as in the CMS settings, changing the code itself can get tricky and problematic especially when you come to update.

You can change the default meta title from the Yoast SEO plug-in > search appearance > Taxonomies tab see here https://www.print4hospitality.co.uk/edit-category-titles/

or you can of course edit individual pages, which of course is not very practical for a site-wide change.

Be very careful with dynamic content.  It is okay up to a point but it does have a number of SEO implications, although I think it's unlikely you would get a penalty.

One complication is, when a search engine crawls asset parameter and it delivers the specified page that will then be cashed by the search engine and delivered through the search results.  The complication comes if a user comes to the side but has a different parameter set, they won't be able to see the content they came to get!  That is a big problem, your bounce rate will be high which eventually could knock you out the rankings entirely.

I would take the professional approach...

Create static pages for all of your important content, if you want you could still include a little bit of dynamic content providing it doesn't change the page too much.

I would completely avoid the no index option, you have nothing to gain as far as I can see and it could cause a lot of damage.

Just interested to know when putting links at the foot of the site some people use no-follow tags.  I'm thinking about internal pages and social networks.

Is this still necessary or is it an old-fashioned idea?

Interested to know if anybody still uses the strategy of pinging links to make sure they get indexed, there are a number of sites out there which offer it.  Is it considered dangerous/spamy?

If I've understood you correctly, all you need to do is to add a tag with the relevant content same as the old one.

I'm interested to know how DA and PA is calculated.

Is it calculated exponentially?  i.e. increases out of proportion compare to the power and quantity.

So assuming all things are equal...   One link of DA40 would be much more powerful than two DA20's?
