Google always changes its algorithms. Besides than adding longer meta descriptions, I don't think there's anything else we should do. In 2018, I'll just keep doing the usual stuff.
The basics will be same as usual for every year. However Content marketing and video marketing will be a big player in 2018.
As not much update till now as the 2017. But you must update your meta. As meta description length has been increased by google. My suggestion is to work with the important link building terms like: guest blogging, blog commenting, forum posting, (don't go for backdated techniques)
Seriously these are your suggestions. Guest blogging is okay but blog commenting and forum posting, I mean really? These things provide mostly (99% time) no-follow links and the least amount they do provide do-follow links passes no link juice. And coming to meta description. If you update your meta description then you will end up as spamming. The best option is that you leave the meta description blank. Let google decide what's best for your page.
blog commenting & forum posting still works for me. Then why not? and yes your thinking is OK. from next posts follow the google's guideline on meta. That's it
Those guidelines are for who want to add meta. If you don't add meta than also its alright Google will pick it up for you. And coming to blog commenting and forum posting. Do they really get you ranked? Or, its just your site's on-page optimization that do that for you?
they won't give you rank true. But a well informative comment can bring you lots of traffic my friend. And well PA/DA backlink will of course give you the authority which is very much important. Isn't it?
If you put it that way than yes they can get you very targeted referral traffic but that's it. I wouldn't care less about DA/PA. Its third party metrics which has nothing to with SEO or whatsoever.
The SEO strategies that will work in 2018 are Content Marketing. Link building is always important and if someone says it's not, don't believe on them because Google never said link building is not necessary. But, the link building techniques or ways you are using it, those are changed. Those are little tricky now. So, write the best quality content that values for your users and builds natural links for your website. Don't go with this suggestion for the link building purpose. These were the effective methods but not now.
Yes, links from blog commenting sites are considered spammy and nowadays most of the blogs provide you the nofollow links so, blog commenting is just a waste of time. But if you like someone's work and want to appreciate the work than you will comment other it is just a waste of time. The forum provides you the nofollow links in the signature and those provide the dofollow are not treated by the SE as quality links.
yea your point is fair enough. It looks like bit spammy if you put your link in the description. But blog comment is still good effective way if you go for PA/DA. Still it's good for authority
But, DA and PA don't matter anymore and these are the MOZ's metrics. For Increasing the authority of the website, build links on the niche and authoritative websites that have a good amount of traffic and rank higher on the SERP for more keywords. Write quality content on your website or publish a blog post with the quality content. Write on the trending topics and earn the natural links.
Yes, DA PA is not necessary. Focus on the quality, optimize the website on page and content matters more than anything.
