SEO Experts Required. Rank 5 to Rank 2?

May somebody help me in my project with some advice please? I aquired to rank my client's website as Rank 5 for high competition KW, now I have to get it higher but somehow It's just not going higher.
My DA, PA, TF, CF is higher than the competitors, but I'm still staying the same position.
I would be very graceful.

How is the on page SEO?

Make sure that's as good as it can be.

there are multiple requirements to rank other than DA PA TF & CF. Probably you're lacking against the social strengths of your competitor , or it can be the quality content , or the missing on-site seo part. check the competitors strategy first and the sources of traffic your competitor have. probably it will help you lot in the long run.

"Social strengths" and "quality content" have shit-all to do with ranking at this point. Okay, maybe social signals could do a little little bit, but I honesty doubt that. Regarding the quality content, that's only good for a bounce rate. Does bounce rate have any super significant impact on SEO? Not really. CTR is much more important. But back to the question.

Any unique content will do, if it's properly optimized and is long enough. There are a few guides regarding ONsite SEO which you should probably read, they can do quite a lot of difference. Phpbuilt made one or two such threads and even though he is a little bit strict with keyword densities, those threads are really helpful.

Regarding the metrics. I can have 1 backlink and TF of 30 straight away. Will I outrank you? Nah, I don't think so.

Also, if I will ever again see, and hell, I saw it even in some marketplace PBN sale threads, that high CF is good, then I will unleash a shitstorm of fury on the toilet. High CF means that the website is more likely to be spammed. High CF is something you do not want. The higher the CF, the worse is the ratio of quality:quantity of the backlinks, simple as that.

Yes and PA/DA are most of the time just toy metrics. I can spam a domain to hell and back and get a decent DA, they are not always that relevant, even though I use these metrics.

try building some exipred web2.0

As per my knowledge once you reach to first page you have to change the targeting method building links is not even then you have to concentrate on improving Average CTR then competition and Avaerage bounce rate goog considers those while deciding whom to keep on top for first page...
added you on skype

I get so sick of seeing posts like "what will it take to rank top 5?" "what do I do to rank #1?" and so on. This forum is LITERALLY littered with thousands of these types of posts clogging up BHW. There is no short answer for such a vague question.

Doing SEO without knowing what you are doing is like giving a monkey a gun. Dangerous stuff. I'd recommend learning before acting.

Before I seem too cranky let me clarify that, the OP needs to do one of two things actually now:

1) Provide much more information about the exact situation, what he's done, the competition, his strategy... everything outside actually listing his site and keywords. This way people can give meaningful input.

or

2) If he doesn't really know what he's doing he needs to ask for help finding an SEO guide, or some learning tools so that he can start doing SEO with a plan.

Monitor those on top 5 very closely and see what it is that they are doing different.
