Indexing your lowest tier is not what you should be doing. The lowest tier exists to help index everything else, and should come from sources that are already indexed, or have clear paths to indexation (internal linkage). This is why comments of all types are typically the favourite for the lowest tier.
After adding internal links and having them re-crawled and indexed by Google, how long does it typically take to see an improvement in rankings?
competitors backlinks analysis worked Surprisingly well for me....
One approach that perfformed surprisingly well was taking care of improving user experience in addition to seo optimization. Such small tweaks as making text more readable, improving page speed nd providing more precise answers to user queries resulted in higher engaggement. In my opinion SEO works most efficiently when the visitor comes first.
I have a similar setup to you and have been doing it for some time and one of the easier strategies to automate. The only downside is we have some time to create accounts on those self-hosting sites and create solid tier 1 and the rest is automating with GSA SER. Do you automate tier 1 too? I am looking to automate tier 1 and still I couldn't find anything permanent. I know Money Robot has decent referring domains from their PBN however their price is insane and it can be used only once or twice per project so not worth it. I am now trying to automate tier 1 also with GSA SER.
What surprised me is that there were many cases when you had to make efforts in improving those pages which have been receiving impressions, but no clicks. sometimes just some small improvements such as more approprieate titles, sections, and internal links could bring muchh better results.
for me, however, the most surprisinng thing was cutting down on content rather than increasing it. deleting the poor quality, redundant pages and making better content from them has really improved the site, as well making the rest of the pages perform better.
the one approach that actually surpased my expectations was concentrating on internal linking that made sense. rather than blindlly stuffing in as many links as i could possibly find room for i created links between pages that were related to each other. this approach worked well in helping search engines understand how my site is structtured.
Bro, this is actually the basic principle of ranking)
