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?

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?

Is it advisable to use only one H2 tag? The template designs for some reason is ended up with multiple H2 tags, I realise if any think it's that each one is that are important and it is all relative. Just trying to assess if it's worth the time and effort to rehash the template. Has anyone done any testing or got any experience? Thanks

Does CDN impact on SEO or not? There seems conflicting ideas as to whether they impact positively or negatively, I realise that if the page loads quicker this is a good thing for SEO and usability of course. Does Google see CDN as just cheating and a get-around for not doing the work from the ground up and using good hosting etc? Do you have any direct experience? All constructive input much appreciated!
