Why a Web-Page Continuously goes down in SERP?

Backlinks is not the basis to rank your site page but the engagement still matters most because it can produce earned quality links rather than building links.

you wait for one week and see what happen and check google webmaster and analytic for more info or check it seo moz and alexa also

Check your competitive. May your competitor build more backlinks compared with you or it may be all your backlinks are still trying to get to be indexed. If all your links are indexed then you can get the SERP improvement. Also, Keep building more backlinks which are relevant to your niche with good quality.

Hi,

If there is sudden drops in ranking then it may due to occurrence of any technical issue. Check if your webmasters shows any error or warnings. Check things like sitemap, meta tags, responsiveness etc. If everything is fine then go through your content once. Check for duplicate contents.

Have you recently boosted your website with social signals and stopped everything suddenly ?
One more thing how often do you update your pages weekly or monthly how many times?>

Your website jumped from 5th page to 11th page for how long? Is it fast or slow?

Solutions for you to dont fall deeper into google.:
Solution #1: Internal linking
Solution #2: Speed up your site
Solution #3: Build links, but not to the page that dropped in rankings
Solution #4: Update your web page
Solution #5: Increase your click-through rate
Solution #6: Optimize your design
Solution #7: Increase your social shares

You’re going to see the best results if you combine all of the tactics, but even then your rankings won’t bounce right back. It typically takes a few months after implementing the strategies above before you start seeing results.

Hello

I am having the same problem, but my keywords in 7th page, but it not getting improved. i am doing backlink in every day, but still, there is no improvement.

Duplicate content generally refers to substantive blocks of content within or across domains that either completely match other content or are appreciably similar. Mostly, this is not deceptive in origin. Examples of non-malicious duplicate content could include:

Discussion forums that can generate both regular and stripped-down pages targeted at mobile devices
Store items shown or linked via multiple distinct URLs
Printer-only versions of web pages

Check your webmaster tools in any case of a "bad link".

Check your competitors if they are building better links than yours or in the worst case scenario make sure none of your competitors is using shady bad techniques to bring you down.

If that's the case build better backlinks and provide better content to show who's the real boss. Don't fall into the "revenge" trap. Just focus on you being better

There can be lots of different reasons, but I don't think that competitors are so strong that website started losing its ranking ... I'd consider two scenarios: (1) google dance - just wait and keep doing good job with promotions; (2) review your internal algorithms, there can be some internal glitches. I had recently a situation when a module stopped functioning and all pages lost meta-information, and I couldn't find it right away. That's way it's important to make a complete audit of the website, identify issues and resolve them. Pay attention to the following key points:
Technical Audit
1. Robots.txt
2. Sitemap XML
3. Broken links
4. Infinite scroll
5. 404 page and referall accuracy
6. Main mirror site
7. Duplicate pages
8. Web- analysis systems
9. Location assignment (if site arrived for promotion)
10. Internal links
11. Human readable address
12. Loading speed
13. Garbage in code
14. Тег noindex
15. Non clickable item in menu in its category. Logo clickability
16. Bread crumbs
17. Encoding in code
18. Absolute and relative internal links
19. HTML and CSS validator
20. Other errors impacting loading speed and page preview
21. Page indexation
21.1. accuracy of indexation. How many in main google index and in general in index
21.2. internet filters
21.3. affiliated sites
22. Re-linking
22.1. spam
22.2. accuracy of page weights
23.1. Content
23.2. update frequency
23.3. top 10 queries leading to Competitors’ content
23.4. text size, unicity
23.5. overspam and overoptimization
23.6. readability, accuracy
24. Optimization
24.1. site structure, addresses, CPU, nesting
24.2. meta data
24.3. pictures
24.4. headers
24.5. contact info
25. Other important points of promotion
25.1. social networks buttons and gadgets
25.2. page snippets
25.3. schema and structured data
25.4. Favicon
25.5. Google maps, Gis, URLs
26. Links, return links, uplinks, competitors links

I have the same problem before one week my site is ranking in 3rd page and now it is not in 100. please suggest me ..

First, most pharma niches are highly competitive. You are not going to rank without a pretty big budget and some serious work.

Outside of the guest posts (which may or may not suck), it sounds like your link building is mostly low quality stuff. Articles, if you are talking about article directories like Ezine, is basically spam. Blogs, if you mean blog commenting, definitely is spam. Guest posting can be okay, but if it is on sites that advertise that they accept guest posts, or through 99% of services that offer guest posts, then it is also probably just more junk.

It can be your competitor are growing backlinks more than you.

40+ competing pages are getting better SEO'd.

Or, you have not create new good links recently and are losing links (some websites go out of business, some get revamped, some get de-indexed), some start adding rel="nofollow" to all outgoing links.

You need more links... good more links.

Have you stopped building links now? if yes, then it was always going to happen.

Hi,

Check for your titles, meta description, URL response etc. Remove redirection of URLs if any.
Use content that is relevant and updated. Try to change your titles and metas according to target keywords.Boost your off-page activities with original fresh content.
