Site Rollback for Careless Website Design That Caused Rank Drop

[jclmns]

New PPC Client (out of necessity) had their site redesigned for mobile without much care given to it by a "SEO Expert". None of the meta data was copied over to the new images and pages, much of the old content was simply deleted, intra site links completely changed.

Huge hits in organic rank, resulting in traffic declines occurred as their lead volume hit zero the following month (April 21 until Present).

Any concerns I should have in doing a simple rollback beyond redirects and GWT (Search Console) ops?

Current plan is

1. Setup redirects back to old site

2. Launch PPC campaign to recover call volume and leads.

3. Optimize old site for mobile simultaneously with simple responsive framework for menu, text.

4. Start disavowing poor-quality links that were added (got 10 with spam rating >4).

5. Eventually move them back to Wordpress and the theme they paid for with site content, meta data, etc all in tact.

No, I cant see any concerns. If re-directing should be no issue with duplication. Sounds like a good plan. Shame about the content deletion hopefully there is a back up.

Did you look up the site in https://archive.org/ ? you should be able to recover lots of the content that was deleted!

Its even possible that some was curated across the web as well, if you need some help looking let me know.
